Product Contents

A new RetroTINK-4K package will come with the following items:

  • 1x RetroTINK-4K unit
  • 1x 8GB SD Card, pre-loaded with software and profiles.
  • 1x USB-A / USB-C SD Card Reader
  • 1x Remote Control
  • 1x USB-A to USB-C Power Cord

The contents do not include an AC adaptor. We recommend using a 5V 2A USB-A adaptor, similar to ones like Apple iPad or Samsung phone chargers. We do not recommend plugging the RT4K into the USB ports of your TV, as they often do not provide enough power and may result in operation errors.

Getting Started

Insert SD card with RT4K firmware, HDMI® output, USB-C power and whatever inputs you wish to use.

The RetroTINK-4K is designed to be powerful, yet easy to use and quick to set up. Here are some steps to get started using the RetroTINK-4K:

  1. SD Card - A card is included with every RetroTINK-4K that includes the launch firmware and profiles. Please make sure this card is inserted in the device, as it is required for proper operation. If you lose the card, any FAT32 SD card 32 GB or less may be substituted.
  2. USB-C Power - Connect a USB-C cable supplying at least 5V/2A to the USB-C power input on the 4K.
  3. Video Output - Connect an HDMI® cable (2.0 or higher / 18Gbps+) from the RetroTINK-4K output to your display.
  4. Video Input - Connect your device's signal to any of the RetroTINK-4K's inputs. More information on supported connections can be found in the Inputs section.
  5. Confirm Video Output - By default, the RetroTINK-4K outputs 4K60. If you don't see any picture, confirm that your display supports 4K60, or press the button on the remote that matches the resolution of your display (1080p, 1440p, or 480p). See the Remote and Output sections for more information.
  6. Select Your Input Source - Press the "Input" button at the top of the remote, then choose the port and signal your game system is using.
  7. Enjoy - Once your video source is visible, you're ready to go! Enjoy the high quality, low latency scaling of the RetroTINK-4K. Time to play the game!

Basic Analog Calibration

With your game up and running, you may want to consider two more steps if you're using an analog video source (note that HDMI® video sources do not require calibration):

Tink4k - Auto-Gain Side by Side Example.png
Auto Calibrate the Gain - The RetroTINK-4K has a function to automatically calibrate the gain, which works well so long as there's a patch of pure white somewhere on the screen. Gain should be applied on a per-console basis.
  • To quickly use Auto Gain, press the "Gain" button on the remote.


Advanced users may want to use the manual gain controls under Advanced Settings > RGB/Component ADC, in tandem with the 240p Test Suite.

Tink4k - Auto Crop Example (no crop).png

Tink4k - Auto Crop Example.png
Crop the Picture - Cropping the picture is how the RetroTINK-4K scales images to the edges of a screen and centers them. For best results, use a screen that has no black or dark edges. Crops should be applied on a per-game basis.
  • There are three ways to automatically crop the picture, which can be accessed via the AUX buttons at the bottom of the remote:
    • AUX1 - "Vertical Only", cropping only the top and bottom edges.
    • AUX2 - "Full Crop to 4:3", cropping all four edges.
    • AUX3 - "Full Crop to 16:9", cropping all four edges and setting the Aspect Correction to 16:9.


You can also manually crop and resize the picture if you wish by going to Advanced Controls > Scaling/Cropping. Head to that section to learn more.

Tweaks, Filters and Beyond

Of course, there is a lot more you can do with the RetroTINK-4K. Here are some more advanced options to explore:

Firmware Updates

The RetroTINK-4K can be updated to any firmware, with new firmware releases adding more new features as they are made.

  1. Power off your RetroTINK-4K and remove the SD card.
  2. Insert the SD card used for your RT4K into the SD card slot on your computer. If your computer doesn't have an SD card slot, you can connect it using the provided USB adaptor.
  3. Download the latest firmware .zip file from the RetroTINK website.
  4. Extract the contents of the .zip file to the SD card's root directory.
  5. Remove the SD card and insert it into the SD card slot on the RetroTINK-4K.
  6. There are two methods for initiating the installation of a new firmware. If you have multiple firmware files on the SD card, the RT4K will always pick the most recent one.
    • Option 1: Power on the RetroTINK-4K, then go to Advanced Settings > OSD/Firmware. In the Firmware update section, select "Check SD Card" to scan for the firmware file, then confirm that you want to install it.
    • Option 2: Hold down the blue Reset button on the back of the RetroTINK-4K, then power it on. The firmware installation will begin automatically.
    • If the LED blinks red, an install error has occurred. Check the files on the SD card and try again.
  7. The RT4K will reboot for about 40 seconds, with the front LED flashing pink and then blue. Once done, it will power on again as normal with a green LED. You're done!

All custom profiles, CSC files, banner images, input modes, mask overlays and modelines will be kept, as those are stored on the SD card instead of on the RT4K itself.

Pause Button

The Remote features one function that cannot be accessed anywhere else: the Pause function. Pressing this will pause the on the current frame and mute the audio. This frame will even be remembered if you switch to a different input source and back.

  • Perhaps the most useful application of the Pause Button is the Deinterlacer/Film menu. Here you'll be able to adjust the deinterlacing settings and see their effects more easily in a scene in motion, letting you tweak them to your liking more easily.

There are a few situations where using the Pause function will have undesirable results, such as loading a different profile, using the cropping tools, or engaging 3:2 Inverse Telecine. Other functions, such as Black Frame Insertion, won't be visible at all because they require new video frames in order to work. In these cases, simply unpause to resume normal operation.

Safe Mode

Safe Mode is an option accessible by pressing the blue Reset button on the back of the unit, or by holding down the "SAFE" button on the remote for two seconds. This causes the following:

  • Loads the Default profile.
  • Sets the input to HDMI® In.
  • Sets the output to 480p at 59.94 Hz.

Safe Mode is intended for use in troubleshooting, as any display that supports HDMI® should be required to support 480p60. It's also handy as a fall-back in case you need to return the RetroTINK-4K to a default state for any reason.

LED Light

The RetroTINK-4K has a front LED light that changes color and behavior to convey information about its operation to the user. Below is a chart for LED light behavior and what they mean.

Color Description
No light The RT4K has no power. No electrons, no business.
Slow Red pulse The RT4K is sleeping, and must be turned on for use.
White The RT4K is booting up, but is not yet ready for use.
Green The RT4K is on and ready for operation.
Yellow flash System files not found on SD card during boot. Check to see if the SD card is correctly inserted, that it has the .rbf system file, and that the rt4k.bin file matches it.
Purple-Purple flash The RT4K is updating the firmware.
Blue-Blue flash Firmware update is successful.
Red flash Firmware update error. Check the files on the SD card and try again (the unit is NOT bricked).

Inputs

The RetroTINK-4K features inputs for a wide variety of signals and connector types, which can be selected in the Input Selection menu. These options can be accessed by pressing the Input button at the top of the remote, or by pressing the Menu button and choosing "Input Selection".

HDMI®

HDMI® Input
HDMI In.png
The RetroTINK-4K supports many resolutions digitally, up to 1920x1080p60 or 1920x1200p60 CVT-rb. It does NOT support higher resolution input, including 1440p and 4K input.

Unlike standard consumer equipment, the RetroTINK-4K can tolerate and adapt to arbitrary and off-spec resolutions.

Front

The RetroTINK-4K offers S-Video (over Mini-DIN) and Composite (over RCA) inputs in the front (which can be concealed / revealed by moving the sliding panel). The red and white RCA jacks are stereo audio inputs. Red/White front audio inputs are active when either the Front Composite or S-Video input is selected (assuming audio input override is not used).

Front Inputs
Front connectors.png Composite To use Composite video, use the yellow RCA jack for video (CVBS/Composite) and the Red/White RCA jacks for right and left audio input, respectively.
S-Video To use S-Video, use the Mini-Din for video (Y/C S-Video) and the Red/White RCA jacks for right and left audio input, respectively.

Rear RCA

The rear RCA jacks support YPbPr (Component), RGsB, and CVBS (aka Composite) inputs.

Rear RCA Input
Rear RCA.png
YPbPr The Rear RCA input supports YPbPr (Component video). The maximum resolution supported is 1920x1080p at 60fps, or 148.5Mhz.
  • To use YPbPr, connect the Red, Green and Blue YPbPr video cables to their corresponding colored RCA connectors, noting that the Red/White pair to the left is for stereo audio input.
RGsB The Rear RCA input also supports RGsB (aka RGB Sync on Green), a flavor of RGB that sends the sync alongside the Green signal. The maximum resolution supported is 1920x1080p 60fps, or 148.5Mhz
  • To use RGsB, connect the Red, Green and Blue RGsB signals to their corresponding colored RCA connectors, noting that the Red/White pair to the left is for stereo audio input.
CVBS on Green Composite video (CVBS) can be used with the Rear RCA inputs. The maximum supported resolution is 480i.
  • To use CVBS on Green, connect the yellow Composite signal connector to the Green RCA jack, then setting the input to "CVBS on Green" option in the Input Selection menu. The Red / White pair of jacks furthest left is for stereo audio input.

SCART

The SCART port is the large rectangular input on the right-hand side of the device. SCART has many different options for video input using the same connector design, as it was designed to carry a wide array of them using a single cable.

  • Two M4x0.7 thread screw-holes sit on either side of the SCART port, 70.4mm apart from each other relative to their centers. These allow for a user-made solution to give a more secure fit for the SCART cable (similar to the HD-15 port's screw-holes).
SCART Input
Scart Input.png
RGBS (75 ohm) RGBS is a form of RGB where sync is sent through a discrete line. The RetroTINK-4K accepts the following RGBS signal formats via SCART: Composite Sync (attenuated), Sync-on-Luma, and Sync-on-composite. They all work by sending information down the Red, Green, Blue, and "Sync" lines. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
RGsB RGsB sends sync down the green input, using only 3 cables. This RGB format is notably used by the PS2 when in 480p mode via SCART. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
YPbPr YPbPr is sent through the Green, Blue, and Red pins, respectively. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
CVBS on Pin 20 Composite video sent through Pin 20, usually through a composite to SCART adapter or if your cable uses sync-on-composite video and you wish to use composite instead of RGB. As with all composite signals, only 240p/480i/288p/576p signals are supported.
CBVS on Green Composite video can be sent through the Green pin. This would be useful if you use a component (YPbPr) to SCART adapter, just plug composite (yellow) into the Y RCA jack (Green). As with all composite signals, only 240p/480i/288p/576p signals are supported.
Y/C on Pin 20/Red S-Video (Y/C) can be sent down Pin 20 (sync) and the Red pins. You will need a S-Video to SCART adapter. As with all S-video signals, only 240p/480i/288p/576p signals are supported.

HD-15

The HD-15 connector (or VGA connector) is commonly associated with PCs, however it's also famously available for the SEGA Dreamcast.

  • Unlike SCART, the HD-15 port does not accept audio. When using HD-15, audio should be input using the RT4K's 3.5mm TRS input (associated with the HD-15 port by default) or the TOSLINK "optical" input.
HD-15 Input
HD-15 (VGA) Input.png
RGBHV RGBHV is a form of RGB where information is sent through 5 lines: Red, Green, Blue, Horizontal Sync, and Vertical Sync. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz. This is most common for PC sources.
RGBS RGsB sends sync down the green input, using only 3 cables. This RGB format is notably used by the PS2 when in 480p mode via SCART. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
RGsB RGsB sends sync down the green input, using only 3 cables. This RGB format is notably used by the PS2 when in 480p mode via SCART. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
YPbPr YPbPr is sent through the Green, Blue, and Red pins, respectively. The maximum resolution supported is 1920x1080p 60fps, or 148.5 MHz
CBVS on Hsync Composite video sent through the horizontal sync line. As with all composite signals, only 240p/480i/288p/576p signals are supported.
CBVS on Green Composite video can be sent through the Green line. As with all composite signals, only 240p/480i/288p/576p signals are supported.
Y/C on Green/Red S-Video (Y/C) can be send down Green (Y) and the Red (C) pins. As with all S-video signals, only 240p/480i/288p/576p signals are supported.

3.5mm TRS Audio

3.5mm TRS Audio
Audio in Analog.png
The RetroTINK-4K allows for audio through a 3.5mm TRS input. This accepts stereo analog audio. By default, this is associated with the HD-15 port, as that port does not accept audio signals.

Optical Audio

Optical Audio
TOSLINK Optical Port on the Tink 4K.png
The RetroTINK-4K offers a discrete optical audio TOSLINK input. This input can accept 2-channel LPCM and compressed surround sound.

Alternate Audio Inputs

The RetroTINK-4K allows you to reassign audio inputs from their default video source. Go to Advanced Settings, and select "Audio Input" under the "Acquisition" section. The "Input Override" option under "Source" allows the audio for the current input video input to be taken from a different audio source. The only exception is that it is not possible to assign HDMI® audio to a non-HDMI® video source. The reverse, however, is possible.

  • This menu also has the Input Swap option, letting you swap the audio input channels (handy for some third-party Saturn cables), or derive mono audio using the left or right channels (useful for single-channel systems like the NES).

HDMI® Output

The RetroTINK-4K only outputs via the HDMI® Out port. Note that the RetroTINK-4K can not output video or audio through any other port.

The HDMI® Output menu allows you to set your output resolution, enable black frame insertion, change your colorspace output (colorimetry), and more. Here is a breakdown of some key functions:

Output Resolutions

The following outputs are readily supported by the RetroTINK-4K, and are provided as the first eleven Output Resolution options at the bottom of the HDMI® Output menu. Which resolutions available by pushing their respective button on the remote are also noted. If you are unsure which resolution to use, use the buttons on the remote to quickly try them.

RetroTINK-4K Output Resolutions
Resolution Description Remote Button?
4K60 Default resolution and framerate for 4k displays, aka 3840x2160p.

Default Resolution for the RT4K

Pressing the Reset button on the back of the unit activates this resolution.

Yes

HDR

HDR is a way for the RetroTINK-4K to output a much more luminous picture for TVs that support it. HDR is intended for use with either Black Frame Insertion or Scanlines and Masks, as it helps compensate for the darkened image.

  • Currently, the only option available is "HDR10 [8-bit]".

The table below shows two photos of an LG-CX displaying the RT4K using the "PVM 600 TVL" profile, under the HDR CRT Simulation folder. It's impossible to communicate the luminance of HDR in SDR, so here the camera had its exposure set for the HDR photo first, demonstrating the luminance gain compared to the SDR photo.

HDR Comparisons - Off-screen Photos
PVM 600 TVL scanlines - SDR.
PVM 600 TVL scanlines - HDR.

Colorimetry

HDMI® Output Colorimetry specifies the colorspace of the HDMI® output. By default, the Auto setting will select Rec. 709, and toggle to Rec. 2100 when HDR is enabled. You may wish to manually set output to Rec. 2020 (without HDR enabled), Adobe RGB or DCI-P3 if your display supports a wider color gamut. This may improve the image quality/accuracy when using the settings in the Color Correction menu.

Sync Lock

Sync Lock controls how the RetroTINK-4K synchronizes the output frame rate with the input frame rate, and handles these input changes.

Older video game consoles didn't always have perfect video timings, and while CRTs typically had no problems working with them, these "imprecise" consoles can sometimes have trouble working with modern TVs and capture devices that conform to a more rigid standard. Some games, such as Silent Hill or Chrono Cross on the PlayStation 1, will alternate between 240p or 480i video modes if you are in-game or in the items / pause menu, respectively. On many displays, upscalers and capture devices, this will create a long delay and a "no input detected" screen for several seconds while the device reorients to the new video mode. The issue of a device taking a gameplay-harming amount of time to change between video modes has been colloquially called the "Chrono Cross" problem. How the RT4K handles all of this can be chosen in the Sync Lock section.

  • Triple Buffer - Operates the output independently from the input, which results in a stable output signal even if the input signal glitches or changes. However, this comes at the cost of a variable lag, usually between a fraction of a frame to a fraction of a frame plus one whole frame. On occasion, you will see judder when frames need to be dropped or repeated in order to maintain sync.
  • Gen Lock - This is the recommended mode as long as your display is compatible with the source's refresh rate. Gen Lock loosely couples the output frame rate with the input frame rate. After a few seconds, the output frame rate will lock with the input frame rate and achieve minimum lag without screen judder. If Gen Lock is giving your equipment trouble, try enabling VRR if they support it.
  • Frame Lock - Tightly couples the input and output frame rates. Any change in the input frame rate will cause a disruption in the output signal and a hard re-synchronization.

VRR (Variable Refresh Rate)

The RetroTINK-4K can flag its output as VRR. While the RetroTINK-4K itself never outputs variable frame rates, settings this flag may be useful to force the display to accept a broader range of refresh rates, including if you're using Gen Lock. It is also useful on some displays to prevent re-buffering and other frame rate changes, which will interfere with the RetroTINK-4K's BFI generator. Lastly, some TVs activate a low-lag mode if they detect the VRR flag, which will improve the gameplay experience.

Deep Color

This option changes the bit color depth of the RT4K from 8 bits (Off) to 10-bits (On), increasing the number of colors in the picture. This can be useful if you've used any setting that adjusts the color of the picture.

  • Engaging Deep Color may cause issues with some equipment like TVs or capture cards, since enabling it while using 4K60 output will exceed the HDMI 2.0 bandwidth spec. In this case, your options are to either disable Deep Color, or use a lower output resolution. PAL systems may have better luck if the 4K50 option is chosen instead, so long as HDR is disabled.

BFI Control

Gives you quick access to the Strobe and Blur functions of Black Frame Insertion. For more BFI controls, head to the Black Frame Insertion" (BFI) section.

Profiles

The Profiles section handles all of the profiles provided on the SD card, as well as any you've put there yourself. Profiles allow you to save your settings to load later. This is where you'll find CRT presets, since they're just saved profiles.

  • For a list of Profiles provided on the SD card by default, head to the Profile Repository section.
  • For a collection of Profiles made by the community not provided on the SD card by default, head to the Community Profiles section.

Load Profile

  • Load From File - Selecting this will bring up a menu where you can navigate through the "profiles" folder on the SD card to load up a specific profile.
  • Load Default - Loads the Default Profile. The Default Profile can never be deleted or overwritten.

The arrangement of profiles in the Load From File menu matches the internal file structure of the "profiles" folder on the SD card. This means that you can alter the folder structure to your liking if you don't prefer how they're laid out by default.

Save Profile

  • Save Current - Overwrites the currently-loaded profile with the current settings. If selected while using the Default Profile, this will work like "Save As New" instead.
  • Save As New - Saves the current profile as a new file named "New Profile X", where X is an ascending number. This will be located in the root "profiles" folder on the SD card, and can be renamed using a PC.

Assign Profile

This section of the menu allows you to assign one of the twelve number buttons at the top of the remote to a specific profile, using the same SD card navigation menu as the "Load From File" function.

Additionally, this is where you can assign a profile to be loaded up when the RetroTINK-4K is Powered Up. This is not the Default Profile, which can never be changed.

Advanced Settings

saying all kinds of stuff about advanced settings introduction make it look fancy and separate from the first part of the wiki oh yeah

Scaling and Cropping

The Scaling / Crop Setup menu is where you can crop and resize the image. Unlike the RetroTINK-5X, by default the RT4K sizes and positions the image based on the cropping, but this can be overridden with the Scaling Mode setting.

Input Crop

The RetroTINK-4K has robust controls to adjust size, positioning and cropping:

  • "Top Trim" and "Bottom Trim" will effectively scale the image up and down in most Scaling Modes.
    • To more easily see the edges 'Italic text'of the Top and Bottom Trims, set the Scaling Mode to "Auto Fill Integer".
  • "Left Trim" and "Right Trim" will adjust the centering of the image, as the RT4K automatically centers the image based on these settings.
    • To shift the image left and right, increase the Left or Right trim to push the image in the opposite direction.

Vertical Pre-Scale

The RetroTINK-4K features the ability to "Pre-Scale" video content, or discard scanlines, at a fractional increment of the source input. Discarding vertical lines results in a loss of vertical resolution. This loss can be useful under certain circumstances, such as creating more accurate scanline rendering for 240p visual content output from consoles that run at higher resolutions (such as the Dreamcast or Wii).

RoTATE

RoTATE (pronounced "roh-tah-tay") is a special feature within the RetroTINK-4K to rotate the image 90 degrees clockwise (right) or counterclockwise (left). This is especially useful for games that may only display their image horizontally, such as many arcade shooters.

RoTATE Example
Standard Output 90 Degrees Right 90 Degrees Left
Rotate example - uncorrected.png
Rotate example - 90 degrees right.png
Rotate example - 90 degrees left.png

The RoTATE mode will only work if the samples per line of your video source is lower than 1024 samples per line (visible in the RGB/Component ADC menu).

  • Because the video of Composite and S-Video is locked to 858 samples per line, no additional tweaking is required when using these input sources.
  • Further, RoTATE mode will only work with 240p, 288p or 360p resolutions. This is important for titles that mix them with 480i.

If you're using RGB or YPbPr input, visit the RGB/Component ADC section of this page for information on ADC and decimation settings to meet the 1024 samples per line requirement. Similar limits apply when using HDMI® sources: use the Input Decimation settings in the "HDMI® Receiver" menu if the horizontal samples exceed 1024 (for example, MiSTer cores that use pixel repetition).

CP Auto Crop

The RetroTINK-4K can automatically crop and set aspect ratio for an input if it is fed a sufficient game screen (although this only works with RGB and Component sources).

Autocrop looks for the black edges of a game image and crops to them, so use a picture that clearly shows the edges of the video for best results. Screens that have any dark edges, as well as letterboxed, pillar-boxed, and window-boxed screens, are not recommended as they will fool the Auto Crop into thinking those are the edges of the image, resulting in an incorrect crop.

CP Auto Crop Settings
Name Remote Button Effect
Vertical Only AUX 1 Automatically adjusts "Top Trim" and "Bottom Trim" to the top and bottom of the game image. Does not adjust Left Trim or Right Trim, and does not change Aspect Correction.
Full Crop to 4:3 AUX 2 Automatically adjusts Left, Right, Top, and Bottom Trim to the image, and changes Aspect Correction to "4:3 (PAR)"
Full Crop to 16:9 AUX 3 Automatically adjusts Left, Right, Top, and Bottom Trim to the image, and changes Aspect Correction to "16:9 (PAR)"

Scaler

The Scaler section in the RetroTINK-4K is where you'll find the tools that allow you to manipulate the geometry of the image.

Aspect Correction

The Aspect Correction setting chooses the Pixel Aspect Ratio, or "PAR", of the image. This is important because it needs to match the aspect ratio of the display the game is expecting to be seen on, referred to as the Display Aspect Ratio, or "DAR".

  • NOTICE - The Aspect Correction controls are only available when the current Input (analog or HDMI®) is a resolution with a variable PAR factor, such as 240p, 288p, 480i/p, and 576i/p. Most other resolutions will lock the Aspect Correction setting to their expected PAR, no matter the input. For example, 720p over the PS3's Component cables will lock Aspect Correction to "1:1 (Sq. Pixel)", while 480p over PS3's HDMI® cables will let you choose yourself.
    • If the Aspect Correction controls are locked, you can still transform the image using the Scaling Factors tools.

The options that are available are:

Pixel Aspect Ratio Description Display Aspect Ratio Use-Case
4:3 (PAR) Uses the common 4:3 Pixel Aspect Ratio, displaying the pixels slightly wider than squares. Pre-HDMI® video game consoles, which expect to be displayed on the 4:3 DAR of CRT televisions.
16:9 (PAR) Uses the 16:9 Pixel Aspect Ratio, displaying the pixels even wider than 4:3 (PAR). Pre-HDMI® games and systems that offer widescreen modes, such as with the PS2 and the Wii.
1:1 (Sq. Pixel) Uses the 1:1 Pixel Aspect Ratio, displaying the pixels as perfect squares. Games and consoles that expect a 1:1 PAR but still output a sub-HD signal, such as PSP, and Game Boy games via the Super Game Boy or Game Boy Player.

If you're using a device that can use more than one Pixel Aspect Ratio, it's important that you set said device to correctly dovetail with the RT4K, so that the game will be shown correctly once it gets to your display.

Scaling Mode

Scaling Mode allows you to select automatic scaling modes or change aspect ratio constraints on manual scaling:

  • Auto Fill - Fills the screen based on the selected Aspect Correction aspect ratio.
  • Proportional - Allows the Vertical Factor to be adjusted while automatically adjusting the Horizontal Factor to keep the aspect ratio selected in Aspect Correction.
  • Free-Form - Untethers the Vertical Factor and Horizontal Factor to allow values outside of the Aspect Correction setting. This setting lets you use the Vert. Factor and Hori. Factor settings to freely transform the image, like on the RetroTINK-5X.
  • Auto Fill Integer - Scales the Vertical Factor and Horizontal Factor to the highest possible integer value without exceeding the screen boundaries, while also respecting the ratio selected in Aspect Correction. We highly recommend using the cropping tools to ensure the picture can be as large as possible while using this scaling mode.

Scaling Factors (Transform Tools)

The Horizontal Factor and Vertical Factor settings allow you to stretch and transform the image, either horizontally or vertically. Each factor diplays the multiplier value, the input resolution, and output resolution respectively.

Which of these are available depends on what option the Scaling Mode is set to. Proportional unlocks the Vert. Factor, while Free-Form unlocks both Vert. and Hori. Factors.

The function can be expressed as a simple formula: [Input Resolution] X [Multiplier] = [Output Resolution].

Horizontal and Vertical Factor Example
Axis Multiplier Input Res. Output Res.
Vert. Factor 9.000 240 2160
Hori. Factor 2.045 1440 2945

Buffer

The RetroTINK-4K allows users to set how much video to buffer before outputting to your screen. The buffer, in conjunction with the Sync Lock mode, are the main determining factors for overall latency.

  • Min. Lag - Sets the buffer to only store to bare minimum number of video lines. This option provides the lowest latency.
  • 1/2 Frame - Always buffers half a frame.
  • 1 Frame - Always buffers a full frame.

Min. Lag is typically compatible, but if you encounter an edge case with screen tearing, try setting this to "1/2 Frame" or "1 Frame".

Note that certain movie modes, such as Inverse Telecine, will automatically force the RetroTINK-4K to buffer a full frame.

Masking Color

The masking colour settings allow you to adjust the colour of the mask that displays in the Scaling/Crop menu. By default, the values a 0 Red, 0 Green and 31 Blue. You can also change whether the masking colour is displayed in the cropping menu only, or always (even when the RT4K menu isn't displayed).

Processing and Effects

The Processing / Effects Setup menu is where you can adjust the pixel interpolation, as well as add Scanlines and CRT Masks.

Where are the Scanline Presets?

If you're a regular user of the RetroTINK-5X, you may be surprised to enter this menu and find that there's no Presets available to choose from. This is because they are stored as Profiles on the SD card.

  • To load an included CRT Preset, head to the main menu, then go Profiles > Load from File > HDR CRT Simulation, then pick one you want to use.

The "bundling" of CRT Presets as Profiles may seem odd to users of the RetroTINK-5X (where CRT Presets could easily be applied to optimal sampling profiles), however this shouldn't have much impact on the final result. CRT displays are inherently a bit blurry as part of their aesthetic (even PVMs and BVMs), so generic sampling is perfectly acceptable to use for them. If you're using a digital source and decimating it (like Nintendo Switch Online or an HDMI® modded system), you may want to simulate the blur using the Horizontal Interpolation Kernel, and / or the Horizontal Blur function.

The only exception to the above is when you're using the LCD scanlines, as the thin lines dividing each pixel won't appear correctly without scaling the image up by a flat number (such as 4.000x or 5.000x).

Interpolation

Vertical and Horizontal Kernel

Interpolation in relation to video processing is a technique to create more visual information on the output that is given on the input. These processes help make a more visually cohesive image, and reduce effects such as shimmering when the image is scrolling. The RetroTINK-4K offers a handful of interpolation options that can be applied independently across the vertical and horizontal axis.

  • Bilinear Sharp - The image is scaled up the maximum integer factor that is within the output size using Nearest Neighbor followed by a bilinear scale to the final output size. This option provides sharp pixels without shimmer at non-integer scaling factors.
  • Bilinear Medium - The image is scaled up 2x using Nearest Neighbor followed by a bilinear scale to the final output size. This option is somewhat softer than Bilinear Sharp but still sharper than regular Bilinear.
  • Bilinear Std - The image is scaled using conventional bilinear filtering.
  • Bilinear Soft - This performs linear interpolation over 4 pixels instead of the standard 2 pixels resulting in a very soft image. This may be desirable to produce horizontal blur for CRT effects
  • Cubic - Interpolation using the bicubic spline kernel which outputs an image sharper than bilinear but softer than Lanczos.
  • Lanczos2 and Lanczos3 - Interpolation using the Lanczos family of scaling algorithms. Lanczos is a popular algorithm that provides good results for natural imagery (i.e. movies) and most 3D games.
  • None - The image is scaled using Nearest Neighborfor completely sharp pixels, but may shimmer if the Scaling Factors are not set to even multipliers (ie set to non-integer factors).

Anti-Ringing

Anti-Ringing is a toggleable option (On / Off) to reduce the appearance of ringing artefacts when using the Lanczos family of interpolation kernels. By default this setting is set to On, but even then it won't actually be engaged unless you're using Lanczos2 or Lanczos3.

Linear Light

Linear Light is a method of image color and brightness reproduction that may provide more accurate scaling and blending. Linear Light will also alter the appearance of scanline effects, which users may consider an improvement or not based on subjective preferences.

  • Linear Light On - The RetroTINK-4K performs inverse gamma mapping at the start of the scaler pipeline and performs all operations in the linear light domain. The output is gamma encoded for SDR modes and PQ encoded for HDR modes.
  • Linear Light Off - The RT4K performs all scaler operations in the gamma domain and only performs inverse gamma at the output if needed for color gamut transforms.

Assuming default SDR settings, for linear light to function properly, you have to manually set input factor and output factor to 2.4 in the Color Correction-> Gamma/PQ menu.
Enabling HDR in HDMI® Output->Transmitter, Enabling Color Space Conversion in Color Correction->Color Space Conversion, or Adobe RGB/P3 in HDMI® Output->Colorimetry will adjust Gamma/PQ settings by default to properly allow Linear Light processing.

More information on the benefits of linear light can be found here.

Scanlines

The RetroTINK-4K has customizable scanline generation which can recreate the look of various displays, including early LCD displays. Scanlines are an effect that simulates the appearance of blank scanlines on a display, similar to what you might see on older cathode ray tube (CRT) monitor or television screens. The effect creates generates black spaces between each visible scanline of video, simulating how lower resolution progressive signals would be presented on higher resolution (480i) displays.

Since scanlines are part of the image drawn by a CRTs red, green and blue electron gun, they scale with the image's pixels, and it's for this reason that the RetroTINK-4K's scanlines behave the same. This means that scanlines will appear thinner depending on the resolution of the input source; 240p scanlines are much thicker than scanlines placed on a 1080p input.

  • For clarity, on a CRT, every line drawn on the display is a scanline. 240p however only uses half of these, resulting in blank scanlines every second row. This causes the scanlines to be perceptible, hence why these blank lines are called "scanlines" despite not being anything at all.

Note: Proper simulation of CRT and LCD effects involves many more factors than just the scanline settings, such as but not limited to: Scaling, ADC Sampling, Interpolation / Filter and Color Correction. If this is overwhelming, please try one of the pre-made profiles first (included on the RetroTINK-4K SD card).

Blank / Black Scanlines

This scanline function determines what formula is used by the scanline generator to translate the replaced video scanline to a "blank / black" scanline.

  • Off - Disables the scanline generator. Further settings in the Scanlines section will not have an effect if Off is selected.
  • Exponential - A scanline pattern that has the softest profile from bright to dark.
  • Gaussian - A scanline pattern similar to Exponential, but with a sharper transition from bright to dark.
  • Super Gaussian - A scanline pattern with a very sharp transition from bright to dark.
  • Linear - A scanline pattern with a straight ramp from bright to dark.
  • Box - A scanline pattern similar to old style emulator scanlines, with no blending from bright to dark. The scanline pattern is either completely on or completely off.

You can adjust the scanlines with the next two settings:

  • Strength - Adjusts the maximum width of the scanline effect.
  • Modulation - Adjust how much the thickness of the scanline effect will change depending on brightness. Specifically, the higher this value, the thicker the black scanlines will be around dark areas of the picture.

If you're inputting an interlaced signal, you should consider going to the Deinterlacer/Film menu and setting the Algorithm to "CRT Simulation". This will cause the scanlines to move up and down every frame, giving a look authentic to how these interlaced signals appear on a real CRT.

LCD Effects

The LCD functions behave differently than the "blank / black" functions, and are instead designed to simulate the appearance of older LCD displays.

  • LCD Mono - Will place a 1x1 pixel border around every upscaled pixel in the image.
  • LCD RGB - Simulates RGB subpixels per each upscaled pixel (similar to how the CRT masks simulate phosphor artifacts).

LCD effects will not look correct unless the both the Vert. and Hori. Scaling Factors have been set to even multipliers (such as 4.000x or 5.000x). LCD RGB looks best if both the Vert. and Hori. factors are the same multiplier.

With LCD functions selected, the Strength and Modulation options change to "LCD Subpixel Str." and "LCD Vert Str.", respectively, and will retain their values. Despite being available for both LCD functions, they only have any effect on the LCD RGB effect.

  • LCD Subpixel Str. - Sets how strong the LCD subpixel masking is. Lower values will more strongly "tint" the subpixels the colour of the upscaled pixel they represent.
  • LCD Vertical Str. - Controls the size of the horizontal line under each pixel.

Color Bleed

Color bleed simulates some of the imperfections of how colors were presented on a CRT. These won't do anything unless a scanline generator is enabled; these won't work with the LCD effects.

  • Red Bleed: Enabling Red Bleed simulates a common CRT effect where the Red beam is softer and less focused than Blue and Green.
  • Red Convergence: Adjusts a vertical offset of the red data within the scanline effect. Can be adjusted from a -10 to 10 offset.
  • Blue Convergence: Adjusts a vertical offset of the blue data within the scanline effect. Can be adjusted from a -10 to 10 offset.

Masks

Masks apply effects equivalent to the shadow masks on a CRT (as well as the similar aperture grilles and slot masks). Since these masks were metal plates that spanned the entire surface of a CRTs glass screen, they're independent of the image drawn by the red, green and blue electron guns. For this reason, masks on the RetroTINK-4K behave the same, and so will NOT adhere to the subpixels of the input you've selected.

The RetroTINK-4K accomplishes the mask effect by tiling an image across the entire screen at 1:1 sizing. Because of this, reducing the RT4K's output resolution will increase the size of the masks.

  • Enable - Turns masks Off or On.
  • Strength - Adjusts the strength of the masks. "+0" is the neutral value, "+10" is the maximum value, while "-10" is equivalent to turning Masks off.
  • Load from File - Takes you to the "masks" folder of the SD card

If you want to make your own masks, head for the Custom CRT Masks section of this page.

Horizontal Blur

The Horizontal Blur function approximates the horizontal blurring present in some CRTs, looking rather like the right-to-left smearing on "3CHIP" Super Nintendos.

  • Function - Can be set to "Off" or "IIR LPF".
  • Cut-Off Freq - Adjusts the strength of the horizontal blur.

If you're wanting to blur the image in a more "traditional" sense, you'll want to use the Interpolation Kernels in the Processing/Effects menu.

Color Correction

The Color Correction Setup menu is where you can adjust the color values and interpretation of the video signal.

Black Frame Insertion (BFI)

Black Frame Insertion (BFI) is a technique to improve motion clarity with high refresh rate monitors. As an example, a 60fps video source played on a 120hz monitor could have a black frame interstitially placed between every frame. The resulting "image-black-image-black" pattern can increase the perception of motion and fine details. If you have a higher refresh rate monitor, a customizable example can be viewed over at Blur Busters.

BFI cannot be enabled unless the following two requirements are met:

  • Set a supported Output Resolution and frame rate - Due to bandwidth constraints, BFI is limited to 1440p or lower resolution output. This also must be a high frame rate: either 100hz or 120hz.
  • Set a supported Sync Lock Mode - BFI also cannot be enabled unless you are in Gen or Frame Sync Lock mode.

If both of these requirements are met, the BFI options will be unlocked.

LCD Saver: LCD display panels may suffer from image retention when using BFI. The LCD Saver helps prevent against this by inverting the order of (video frame)-(inserted frame) at the timer value set. LCD Saver can be set to 0, 1, 5, and 10 Minutes. When the frame order is inverted, it may create a momentary glitch in the video output. Note that setting the time value to 0 will display a message screen warning the user of possible LCD panel image retention.

BFI Control

Black Frame Insertion (BFI) Settings
BFI Example Diagram.png
Strobe: Strobe controls how the output frame rate is divided into the input frame rate. As depicted in the diagram, with Strobe 1, the 60Hz input frame is flashed one time at 240 Hz. At Strobe 2, the 60Hz input frame is flashed twice at 240Hz, with black frames in between. Alternatively, a 60Hz source within a 120Hz output would display for 1/2 of the time 120Hz output window.

Blur: Blur is a duty cycle modifier that works in relation to Strobe to change how many frames the source video is presented in relation to the black frames. In the example diagram (60Hz Source inside a 240Hz output), a Blur of 1 would display the source video 1/4 of the 120Hz window, a Blur of 2 would display the source video 2/4 of the 120Hz window, and a Blur of 3 would display the source video 3/4 of the 120Hz window. Some relationships of Blur and Stobe are locked, such as a 60Hz video source in a 120Hz output window, which would only allow a Blur of 1 (1/2 of the output 120Hz window).

More information about BFI can be found at Blur Busters.

BFI Color

The BFI Color settings allows the user to change how the inserted frame appears.

The Blending Mode setting selects between the following functions:

  • Solid: Creates a grayscale inserted frame that can be adjusted with any of the Red, Green or Blue BFI Color settings. A lower BFI Color numerical value is darker, higher is brighter.
  • Alpha: In this mode, the inserted frame is a duplicated video frame with a transparent alpha overlay darkening the inserted frame based on the BFI Color setting. A lower BFI Color numerical value is darker/more opaque, a higher value is brighter/less opaque.
  • Solid Color: Sets a solid inserted frame with an RGB-assignable color from the BFI Color selections.
  • Alpha Color: Inserts a duplicated video frame with an alpha color overlay. The color of the alpha-blended frame is set from the R-G-B BFI Color values.

The Red, Green and Blue BFI Color values allow for customizable colors in the Solid Color and Alpha Color modes, and are an interlocked numerical valued for Solid and Alpha blending modes (R-G-B values cannot be adjusted separately).

Deinterlacer and Film

The Deinterlacer / Film Mode Setup menu allows you to adjust settings for use on interlaced sources, such as deinterlacing methods and Inverse Telecine.

While tweaking the options under the Mode and Motion Adaptive Settings sections, we suggest using the Pause Button to pause the video on a frame with motion. This will allow you to see the effects of the deinterlacing more easily.

Mode

There are six deinterlacing algorithms to choose from:

  • Motion Adaptive - Uses an algorithm to determine whether to use Bob deinterlacing for areas of the screen that change, or Weave deinterlacing for areas that stay the same. Can be further tweaked in the Motion Adaptive Settings section.
  • Weave - The current field remains on-screen while the next field is drawn, 'weaving' the two fields together. This is the same as 'disabled' in video players such as VLC, and will result in combing artifacts.
  • Bob - Doubles the vertical height of each line to fill the full frame. This causes the image to appear as if it's moving up and down, since the two fields are not aligned in the interlaced signal, but preserves temporal resolution of interlaced video.
  • Linear - Linear interpolated Bob (i.e., rather than a pure linedouble, line 2 is the average of lines 1 and 3, line 4 is the average of lines 3 and 5, etc.).
  • Blend - The frame is created by averaging lines from the two most recent fields. Produces ghosting.
  • CRT Simulation - Similar to Bob, but additionally changes scanline behavior to match that of interlaced content on a real CRT. If Scanlines have not been enabled, this mode will appear identical to Bob. See below for more details on this algorithm.

CRT Simulation

The CRT Simulation algorithm is unique enough to warrant its own section. It's used to to simulate the way 480i content is displayed on a real CRT: each frame of a 480i image is actually only 240 lines, and each new frame switches to using lines that were unused in the previous frame. Because of this, CRT Simulation will appear identical to Bob deinterlacing unless you use one of the Scanline functions enabled in the Processing / Effects menu (since they simulate the unused lines), and are viewing interlaced content.

CRT Simulation will also cause your crop settings to be displayed incorrectly, so be prepared to redo your crop after enabling this feature.

  • There is one thing to keep in mind when using this feature: the output frame rate of the RT4K must match the input signal's frame rate in order for the effect to be displayed correctly. This is important if you're using a PAL system, which run at 50 frames per second: if the RT4K is outputting at 60fps (as it usually does by default), the CRT Simulation will not appear correctly for PAL content!

Motion Adaptive Settings

Motion Adaptive settings apply only to the Motion Adaptive Deinterlacing mode, allowing you to adjust it to your liking.

  • Sensitivity - Adjusts the sensitivity of Motion Adaptive, between "Min", "Medium", "High" and "Max". The higher this is set, the more weaving will be present for moving parts of the screen, at the benefit of a stabler look for static parts of the screen. Many games will look just fine on the Min. setting, however several games may require Medium or higher. For example, Burnout 3: Takedown on PlayStation 2 has a subtle flickering and noise-like dithering that throws off the Motion Adaptive Deinterlacer for still parts of the screen.
  • Noise Threshold - Adjusts how much low-level changes are ignored, so that the deinterlacer doesn't fall back to Bob deinterlacing unnessecarily. Useful for content that has noise and / or dithering present.

Bob Settings

The only Bob Setting here is the Bob Offset, which adjusts adjusts how far apart each field is from each other. It can be set between "-3" and "+3". This setting is useful for 240p games that were poorly ported to run at 480i, such as Megaman Anniversary Collection on PlayStation 2.

Auto Calibrate

Auto Phase

Any game screen is sufficient for automatic phasing, but it is recommended to use the 240p Test Suite or other sufficiently patterned screen for eyeballing results. whether you've set automatic sample detection using that menu, or you manually selected Decimation Factor in the ADC page, selecting Auto-Calibrate Phase makes the RetroTINK-4K automatically select the best Decimation Phase and Sub-Phase for your current picture and should give you the sharpest results. It is recommended you run this 3-5 times to make sure the same factors and phases are consistently chosen.

Auto Gain

The Auto Gain function will calibrate the gain levels for the current input, however it only works for RGB and YPbPr sources.

  • To use Auto Gain, go to a game screen which has a patch of colour that should be pure white. When you enable the Auto Gain function, the RT4K automatically calibrates the Gain levels based on that white patch.

Auto Gain only works in calibrating the overall brightness Gain, not the individual color gain. You may need to manually adjust the individual colors a few ticks more for in the Gain section to get the true RGB code (255) for a given color. We highly recommend the use of the 240p Test Suite for this task.

Auto Gain must be calibrated on a per-console basis, meaning it will need to be set between different systems. This applies even across different units of the same system, such as two Super Nintendos, as their picture output will have degraded slightly differently.

Sample Rate Detection

The Sample Rate Detection menu is where you control how the RT4K automatically detects the sample rate of a given analog source. This menu is only functional when an RGB or Component input is in use.

Sample Rate Detection Overview

The RetroTINK-4K can take advantage of sampling and scaling algorithms to seamlessly change settings when it detects a horizontal resolution change. This is useful for many analog retro gaming consoles, but requires knowledge of their "Master Sampling Rate." Please consult the table below to see which resolutions are available for consoles where automatic sampling detection is recommended.

Once you know the master sampling rate of your console, set that console's ADC Sample rate in the "Sample Rate Detection" menu under ADC Sample Rate, and turn both "Auto Dec. Factor" and "Auto Dec. Phase" to "On." Once you enable those options, if you know which resolutions you'll use, scroll down to that resolution to enable that horizontal resolution's detection and the RetroTINK-4K should automatically switch to a different set of settings whenever it detects that particular resolution is used. This process will help automatically set Decimation Factor and Decimation Phase in the ADC setup.

Note: You may be tempted to turn on every resolution, but if you know your console won't use it, consider turning that resolution off to help with the detection speed.

System

The System selection of menus relate to the RetroTINK-4K itself, including the On-screen display, firmware updates, and displaying various status screens.

OSD and Firmware

This menu allows you to load in your own Banner. The SD card comes pre-loaded with a default RetroTINK-4K banner, FirebrandX's banner displaying Firebrand from Demon's Crest, and two moon banners (both of which intentionally do not display the moon in a perfect circle).

Here's some information on how banners work on the RT4K:

  • Banners are stored in the "image" folder of the SD card.
  • Banners must be 24-bit BMPs in order to work with the RT4K.
  • 320 x 128 is the recommended pixel dimensions. It can be larger, however only the upper-left 320x128 pixels of the image will be drawn.
  • An RGB value of "255, 0, 255" (a pink colour) will be treated as transparency.
  • If a Profile doesn't have a banner image specified, the file named "default.bmp" will be loaded instead. This lets you determine your own default banner image.

On Screen Display

This section allows you to adjust facets of the On Screen Display, including the menu.

  • Position - This lets you set whether the menu is displayed on the Left side of the screen, the Center, or the Right side of the screen. This is set to "Left" by default.
  • Auto-Off - Lets you determine how long the menu will wait before disappearing (as if you pressed the menu button). This is set of "Off" by default, but you can set it to turn the Menu off after up between 10 - 100 seconds (and anything in-between in 10 second increments).
  • Hide Input Res. - Turning this on will mean the RT4K will not display the current input and resolution in the top-right corner of the screen every time it changes. This is useful if you're capturing or streaming games that switch resolutions.
  • Enable Debug OSD - This option allows you to permenantly display one of the three Status Pages or the Diagnostic Console.

Firmware Update

This option allows you to Check the SD card for the two files needed for installing new firmware to the RetroTINK-4K. For more information on how to install new firmware, head to the Firmware Updates section.

Status

Displays the Status menu, letting you learn more about the current status of the RetroTINK-4K. For more information, visit the Device section of our GUI Map.

Diagnostic Console

Shows the 30 most recent actions in the RetroTINK-4K's operations. Or something?

Displays the About Page, containing the following information:

  • About
    • Device - Displays information about the RT4K's hardware version.
    • FW Version - Displays the current firmware name.
    • Device ID - Displays the ID of the RT4K.
  • Resources
  • Thanks!
    • "This project would not have been possible without the support of everyone who has helped over the years. Thank you all so much for everything and we hope this device brings you countless hours of joy!"

System-Specific Methodology

The System-Specific Methodology section is all about highlighting how you can use the RetroTINK-4K's various features to improve the experience of using your video game systems beyond just plugging them in. This can range from setting 1:1 pixel aspect ratio for Super Game Boy on the SNES, to dovetailing with the Sharpscale Plugin on the PlayStation TV.

NES / Famicom

The Famicom (or Family Computer) is the original Japanese version of Nintendo's landmark console, while the NES (or Nintendo Entertainment System) was released in all other regions. All Famicom / NES systems will be marked as such on the front, so simply read that to tell which one yours is (particularly useful regarding the top-loading redesigns). These systems render games in 256x224.

  • The NES family renders and outputs all audio in mono via the white RCA jack (left speakers). To account for this, go to Advanced Settings > Audio Setup, then set Input Swap to "Mono (Left)".
  • Some NES family games, like Super Mario Bros. 3, have visual errors visible on the left and right sides of the screen. These can be removed from view using the cropping tools.

The NES / Famicom can only output either Composite video or RF (with one rare exception). You will need at least a composite signal to connect directly to the RT4K. Use the list below to tell which one your system outputs:

  • Composite signals are supported by the RetroTINK-4K. This can be used on either the front yellow plug, or the rear green plug.
    • Original "Front-loading" NES (NES-001).
    • Top-loading "AV Famicom" with the rounded power switch and flat cartridge slot.
    • Sharp's "Twin Famicom".
    • Sharp's "Famicom Titler" (also capable of S-Video).
  • RF signals are not normally supported by the RetroTINK-4K. These models support RF output:
    • Original Famicom w. hard-wired controllers.
    • Revised "Top-loading" NES with a rounded cartridge slot and power switch.
    • The RF Modulator output from the original "Front-loading" NES-001, which has softer sound compared to the the sharper Composite output.

Super NES / Super Famicom

The majority of Super NES / Famicom games run in 256x224 resolution, while a select few games run with a mix of the following: 512x224 in the whole screen for menus, 256x224 for most of the image while running 512x224 over certain parts of the screen to create transparency effects, or the same but using 512x224 resolution to allow sharper text on the screen. It is recommended to run the Super NES in 512x224p mode to make sure you get all available detail. (https://consolemods.org/wiki/AV:RetroTINK-5X_Pro#512_%22Hi_Res%22_Games)

We recommend using a Super NES model number SNS-001, or Super Famicom model number SHVC-001, and an RGB SCART cable wired for Sync-on-Luma, as this works with both of the aforementioned models. There are internal revisions of these models, noted as "1-Chip" on the motherboard, and the 1-Chip-03 does not work with Composite Sync. There is a revised model, SNS-101 and SHVC-101, also known as the Super Nintendo Junior. This model only supports composite video.

[Picture Here: 1-Chip without gain adjustments vs 1-Chip with gain adjustments]

As noted, there are revisions of the original model Super NES, noted by the "1-chip" on the motherboard. The 1-chip boards have sharper yet brighter video, while the non-1-chip boards have a "smeared" and slightly darker look. We encourage using the auto-gain functions in the ADC to correct the video on both models.

[Picture Here: Non-1-Chip vs 1-Chip]

Profile included for automatic switching between 512 and 256 in Display Aspect Ratio, for both SCART and HDRV YPbPr cables.

Super Game Boy

The Super Game Boy Cartridge allows you to play original style Game Boy and Game Boy Color cartridges on your TV using the Super Nintendo, and adds borders. Once dialed in, Game Boy games are rendered in a 160x144p window inside a 256x239p canvas. However, Game Boy games were expected to be displayed on the square pixels of their screens, unlike the rectangular CRT pixels that the SNES expects.

  • For correct Super Game Boy pixels, go to Advanced Settings > Scaling/Cropping, then set Aspect Correction to "1:1 (Sq. Pixel)".

[Picture Here: Generic SGB vs Optimized 15x]

Profile included to maximize the Game Boy window to the screen.

Nintendo 64

Unfortunately, no stock Nintendo 64s support RGB without modding. All stock N64s support Composite, all NTSC N64s support S-Video, French N64s support SECAM S-Video, and some PAL N64s do not support S-Video at all.

All N64s have 3 levels of video processing that keep it from being as sharp as the PlayStation and Saturn:

  1. All games scale their image to 640 pixels wide. Many games were rendered at different resolutions but the N64 will scale to 640.
    • Many games render at 320 pixels wide and, as a trick, you can double your ADC Decimation factor to "correctly" render games in their original resolution. This trick only works for games that render at 320 pixels wide, and do not work for games that render at other resolutions that are not 320 or 640 pixels wide.
  2. Software level anti-aliasing. This can be disabled by patching ROMs or using a Gameshark to disable the effect.
  3. Hardware level anti-aliasing. This can't be disabled without a physical mod.

[Picture Here: AA enabled vs AA disabled]

[Picture Here: a 320 game with the trick used vs left at 640 (should be the same)]

[Picture Here: a non-640 or 320 game with the trick used (should look worse)]

Pokemon Stadium Game Boy Tower

Pokemon Stadium's Game Boy Tower allows you to play Pokemon games on your TV, similar to a Super Game Boy, and even uses the Super Game Boy borders. The issue, however, is the scaling noted above. These games render at 160x144p inside a 256x239p canvas, which is then scaled to 640 pixels wide. You will not get a sharp picture out of this setup due to that factor alone. It is recommended to play in a generic or default profile.

[Picture Here: SGB vs Pokemon Stadium]

Nintendo GameCube

For the purposes of use with the RetroTINK-4K, it is highly recommended to use a DOL-001 GameCube, which has the digital out port, and an Insurrection Industries Carby which outputs crisp digital video and can connect to the HDMI® input port of the RT4K. If you insist on buying YPbPr cables, we can only recommend the OEM D-Terminal cable with a D-Terminal to Component adapter, or the OEM component cable.

Most GameCube Games will run at 480p, a progressive mode is activated by holding B when the GameCube boots up a game.

Swiss, the Anti-Flicker Filter, and Horizontal Frame buffer Width

While Most GameCube games run at 480p and progressive mode is relatively easy to access, many GameCube games use an "anti-flicker-filter" by default, which will soften the image. Most of these filters can't be turned off in-game, but the homebrew software Swiss will allow you to boot games, including your own disks, with the anti-flicker filter turned off. As an added bonus, newer versions of Swiss automatically turn the filter off and boot your game in 480p.

[Picture Here: game with anti-flicker filter on vs off]

[Video here: Smash Bros Melee turning the flicker filter on and off]

A few GameCube games scale their image to fit the console's frame buffer before output. Swiss allows you to turn this off and shows the image at its original framebuffer width, and you can use the RT4K to scale it back, for a small sharpness gain.

[picture here: Framebuffer width left alone and the framebuffer width option turned on, with the RT4K used to scale back to the intended resolution] (I don't know what game to use)

240p Games

There are two GameCube games that run at 240p: Megaman X Collection, and the NES games in the Zelda Collector's Edition Promotional Disc. This means you do not have to enable 480p to run those games and can sharply scale these games on the RT4K.

[Picture Here: Megaman X on Super NES vs GameCube]

Game Boy Player + Game Boy Interface

The Game Boy Player is a popular add-on to the GameCube that allows you to play Game Boy, Game Boy Color, and Game Boy Advance games on your TV. The Game Boy Player Disk does not sharply render games onto the screen, but you can use the homebrew software Game Boy Interface to sharply render games into the RT4K. A specific flavor of GBI was created to take advantage of the Insurrection Industries Carby and the TINK 4K's HDMI® Input. Please use files gbihf-rt4k-HDMI.cli, gbihf-rt4k-HDMI.dol+cli or gbihf-rt4k-HDMI.gci included with GBI and follow the instructions noted here.

Profiles included for 13x scaled GBA games and 15x scaled GBC games.

Nintendo Wii

The Nintendo Wii is a very versatile console: it plays GameCube Games, Wii Games, and many classic retro titles through emulators as part of the Virtual Console lineup. The Wii also has easy to find YPbPr component cables and can easily support 480p across all Wii software through its component cables, making it a popular option for playing GameCube games. The Wii only supports 3 resolutions: 720x240p, 720x480i, and 720x480p. Please read on for more information on getting the sharpest possible picture from a Wii.

Profile included for basic generic output. It is recommended you use this for basic Wii use.

Virtual Console

Many Virtual Console games output at 240p when the Wii is in SDTV mode, and they will line double to output at 480p in EDTV mode. All virtual console games scale the image to 640 pixels wide, so it is recommended you use the default or generic profiles for playing virtual console games. Also of note: NES Virtual console games are rendered many shades darker than an original console, as an anti-epilepsy measure.

[Picture Here: Donkey Kong on Super NES vs Donkey Kong on Wii with generic settings]

USBLoader GX, and Counteracting the Anti-Flicker Filter, 480p LPF, and the Framebuffer Video Width

Homebrew called USBLoader GX allows you to activate or deactivate code before running games, even on your disks.

Most Wii games will apply an anti-flicker filter, even at 480p, which results in a softer picture. Use USBLoader GX's options to turn this off for Wii Games. If you wish to run GameCube games, you will need to turn the anti-flicker filter off separately in either Nintendont or Devolution, but USB-Loader GX does have these options in its menu.

[Video here: Super Smash Bros Brawl's settings menu turning the anti-flicker filter on and off]

There is an option in USBLoader GX called the "480p pixel fix" which makes the game look much sharper. It only works with RVL-001 models with the internal CPU-01 motherboard.

[Picture here: Wii game with 480p pixel fix off vs on]

You can get even sharper picture from the Wii by enabling the "Video Width: Framebuffer" option in USBLoader GX. This will make games output in their original rendering resolution, which you can then rescale using the RT4K to get a much sharper picture than originally intended at the "correct" aspect ratio. As an added bonus, NES and Super NES games will render at 512x224p with this option turned on, which you can use a doubled decimation factor to treat a game like its original 256x224 resolution, and get picture on par with their original consoles.

[Picture Here: Megaman X Super NES Optimal vs Wii Optimal]

Nintendo Wii U

It is highly recommended to use the Wii U's HDMI® output instead of its Component output. This is because the analog video is duller, and has less sharpness (even compared to Component from the PS3 and 360).

  • The Wii U's HDMI® only outputs in limited range. To account for this, go to Advanced Settings > HDMI® Receiver, then set Input Range to "RGB Lim.".

Nintendo Switch

Nintendo Switch Online Games

it is highly recommended to use 1080p output for the NSO emulators and turning on "Pixel Perfect" in their settings under "Game Screen" and to also turn off "Show controls in game" under "Control Display," and to turn off "reproduce classic feel" on the Game Boy and Game Boy Advance apps. This way, all games output a perfectly integer scaled, line-multiplied output for their games.

[Picture Here: The Legend of Zelda, Oracle of Ages on GBI 15x vs Switch Optimal 15x vs Switch no adjustments 14x] for GBC games

SEGA Master System

The original model of the Master System supports Composite and RGB output (S-Video is not supported without mods). The second model, the "Master System II", cannot be used with the RetroTINK-4K without modding, as it only supports RF output.

  • Master System games are infamous for having borders of solid colour around the game graphics. These can be removed by going to Advanced Settings > Scaling/Cropping and using the Input Crop trim tools, but be mindful! Master System games can use two horizontal resolutions: 248 pixels and 256 pixels, and some games will use both of them. The safest option is to crop to a 256 pixels wide screen, which will leave a column on the left-hand side of 248 pixels wide screens. You could also have an additional profile just for 248 pixels wide screens.
    • The Auto Crop tools will not work here, as they will consider the coloured border to be part of the image (it technically is, if still unsightly).
  • The Master System also has rather dim video output compared to other systems. You can fix this by going to Advanced Settings > RGB/Component ADC and adjusting the Gain while using the 240p Test Suite. You can also use the Auto Calibrate Gain feature, which works best if there's a patch of solid, pure white somewhere on the screen.

SEGA Genesis / Mega Drive

Recommended output: RGB

For practicality, "Genesis" refers to both the SEGA Genesis and the Mega Drive (it's Japanese and European name), as they are functionally identical as far as the RetroTINK-4K is concerned, outside of NTSC and PAL standards.

  • The SEGA Genesis has three "240p" output resolutions: 320x224, 256x224. A third resolution, 480i, is only known to be used in the 2 Player VS modes of Sonic the Hedgehog 2 and Combat Cars.

Certain Genesis games will display coloured dots along the bottom edge of the screen. Known as CRAM (Colour RAM) dots, these would have been in the overscan area of most CRTs and thus invisible to the player, but are quite prominent on modern displays. You can hide them by going to Advanced Settings > Scaling/Cropping and adjusting the Bottom Trim value. You should not use Auto Crop, as it will consider the CRAM dots to be the bottom edge of the picture.

Sony PlayStation

All Sony Playstation models support RGBS. It is recommended to use a well shielded SCART cable that uses Sync-on-Luma.

Resolution Switching

PlayStation games will switch resolutions often, usually horizontal resolutions like 256, 320, 384 and 512, but occasionally vertical resolutions as well with 480i. The PlayStation is a perfect use for the Automatic Sampling Detection feature of the RT4K. To help with switching vertical resolutions quickly, please enable Triple Buffer in the RT4K's Output menu.

see this part of the 5x wiki https://consolemods.org/wiki/AV:RetroTINK-5X_Pro#Resolution_Switching

Profiles included will automatically switch to all resolutions. You may want to consider researching your game collection and see if you can turn off any resolutions that you won't use, for faster response from the auto sampling detection.

Sony PlayStation 2

The PS2 outputs 240p, 480i, 480p, and 1080i, and supports RGB as well as YPbPr. For simplicity, it is highly recommended to use YPbPr cables because the RT4K will automatically detect and switch to all those resolutions seamlessly. The PS2 will use RGBS for 240p and 480i, but will switch to RGsB for any resolutions above that. While the RT4K supports RGsB, it does not automatically switch from RGBS to RGsB, you will need to change the input manually.

All PS2 games will output either 512 pixels wide or 640 pixels wide. [sic]

PS1 Backwards Compatibility

PS1 games on PS2 use a different set of optimal sampling numbers than the PS1 console.

Sony PlayStation Portable

PSP models PSP-2000, PSP-3000, and PSP-N1000 (aka PSP GO) can output to a display. It is highly recommended you use component cables with the RT4K.

PSP games are rendered at 480x272p. When they are displayed on a television with component cables, they render a 480x272p picture inside of a 720x480p canvas. You can use the RT4K to upscale the image to fit the screen. You will get the sharpest integer scaled picture at the expense of cutting off 2 vertical pixels.

[Picture here: PSP left alone (4.5x scale) vs PSP scaled to 8x]

PSone Classics on PSP

PSone Classics are PS1 games played on the PSP, and use a different set of optimal sampling numbers than the PS1 and PS2 consoles.

  • PSone Classics can be output at their original resolution. On the PSP, go to Settings > Connected Display Settings, then set Component / D-Terminal Output to "Interlace".

[picture here: ps1 console optimized vs ps1 classic]

Sony PlayStation 3

The PS3 supports HDMI® output, which is recommended for the sharpest possible picture with the RT4K.

  • The PS3 supports outputting PS3 games at 720p, 1080i and 1080p, which the RT4K supports. However if you do not have an option enabled (such as 720p), the PS3 will use a different one. To avoid this, on the PS3 go to Settings > Display Settings, then pick "Video Output Settings". In the new menu, choose "HDMI", then "Custom". In the list, ensure that 720p, 1080i and 1080p are all selected, then press Right and then X to save your settings.
  • While the PS3 does support up to 1080p using component cables, it's softer compared to HDMI® output. However many users choose it anyway, as the PS3's HDMI® output always uses HDCP (High-bandwidth Digital Content Protection) with no option to disable it like on PS4 and PS5.

[Picture Here: HDMI® vs YPbPr]

PSone Classics on PS3

PSone Classics on PS3 can render to 480p, but scale the image to fit the 4:3 aspect ratio. For the sharpest picture, use these settings:

  • On the PS3, go to Settings > Game Settings, then set both PS - Upscaler and PS - Smoothing to "Off".
  • On the RT4K, go to Advanced Settings > Scaling/Cropping, then set Vert. Pre-Scale to "1/2".

[Picture Here: PS1 console optimized vs ps1 classic]

Sony PlayStation TV

The PlayStation TV (called the Vita TV in Asia) allows you to play Vita, PSP, and PSone Classics on your TV through HDMI®. By default, all output from the PlayStation TV is soft because of the following factors:

  1. All software has a bilinear filter applied
  2. All software is scaled to the PSTV's selected output resolution
  3. Vita software is internally scaled to 960x544p regardless of its original rendering resolution. This applies to Vita handhelds as well
  4. PS1 Classics are unevenly, horizontally scaled to 4:3.

To counteract this for the sharpest possible picture, we highly recommend installing custom firmware on your PSTV and installing the Sharpscale plugin to counteract all the above effects applied to the PSTV.

Sharpscale Plugin

See an overview of sharpscale here. The following suggestions only work when sharpscale is enabled with the following options:

[picture of sharpscale plugin with the following settings enabled]

PSTV Sharpscale Options
Option Name Option Choice
Scaling Mode Integer
PS1 Aspect Ratio Pixel

Vita Games

When Playing a Vita Game, the PSTV outputs a 960x544p picture inside of a 1280x720p canvas. Use the following settings to get the sharpest integer scaled picture for Vita Games. These settings cut off 4 vertical pixels from Vita games.

RT4K PSTV Vita Settings

Top Trim -90
Bottom Trim -90

[Picture Here: Steamworld Dig 2 with sharpscale disabled vs enabled and optimized]

PSP Games

The PSTV also outputs a 960x544p picture inside of a 1280x720p canvas. Use the following settings to get the sharpest integer scaled picture for PSP games. These settings cut off 2 vertical pixels from PSP games.

HDMI® Receiver Setup
Input Pixels 2
Scaling/Crop Setup
Top Trim -45
Bottom Trim -45
Vert. Pre-Scale 1/2

[Picture Here: Final Fantasy IV with sharpscale disabled vs enabled and optimized]

PSone Classics on PSTV

Sharpscale will allow you to get the sharpest picture for PS1 games, but the behavior is not optimal. With the Integer Scaling Mode setting enabled in Sharpscale, some resolutions will use the full vertical space, and others will only scale to 480 vertical pixels inside 720p. it is recommended you look at the resolutions supported by your game before you use sharpscale with the RT4K and see if it is worth avoiding the headache. If you set PS1 Aspect Ratio to 4:3 in the PSTV's settings, the PSTV will force all games to fit, but they will not evenly scale horizontally, resulting in shimmering pixels.

[Picture Here: PS1 console optimized vs pstv optimized]

Sony PlayStation 4

TurboGrafx-16 / PCEngine

Microsoft Xbox

Preferred output: YPbPr.

Up to 720p available with custom firmware

Microsoft Xbox 360

The cable you should use for your Xbox 360 may vary by model.

  • For Xbox 360 models made in 2007 or later, HDMI® output is available and should be your first choice, since HDMI® cables are readily available.
  • The earliest Xbox 360 models only offer A/V video output. Unlike the PS3 and WiiU however, the 360's component video is quite sharp, so it's a good alternative to HDMI® if that's what you need / prefer. A/V output was standard alongside HDMI® for most of the 360's life, except for the 360 E revision.

PSP Download 2 Sets Decimation Factor to 2 and Prescale to 1/2

The Playstation TV outputs a line-doubled 272p window into a 720p canvas. Upscaled 8x to 2160p. Cuts off 4 pixels vertically.

PS1 Generic The Playstation TV will output the PS1 game to an integer scale of its signal that will fit inside 1280x720p.

Use this profile for PS1 games that switch between many resolutions often. 480i will scale 1x. 512x224p and 640x224p will scale 2x. 384x224, 320x224, and 256x224 will scale 3x.

The following profiles require a slight change in Sharpscale settings. These profiles are best used with games that stick to one resolution for the majority of their gameplay. Do not use these with Chrono Cross or Silent Hill, their menus will cut off vertically

Computer Specific

FM Towns

FM Towns computers once hitting white desktop variants output different video displays with some models performing internal upscaling conversions from 24khz to 31khz as well as some models performing 15khz to 31khz with adjustments in the TBIOS configuration file. EA and Pentium type desktops only output 31khz video modes. The below profiles are meant for all towers, UX, UG, UR, HG and HR models which are all models that do not perform internal conversion.
FM Towns will require a custom profile for any displays at 24khz

Sharp X68000

Sharp X68000 is unique with its outputs primarily being 15khz and 31khz. A few games have hidden selectable 24khz display modes.

PC-8801

PC-8801 computers will output either 15khz or 24khz depending on the dipswitch settings in the back. If dipswitch settings are incorrect, games will refuse to boot and crash the computer. The 15khz VGA detection in the RT4K works very well for PC8801 and most video modes won't require a profile.
A 24khz signal will require a profile to display properly.

Notes

Deinterlacer -> -> Motion Adaptive Settings -> Sensitivity


(medium and high options might be might be reversed) Controls combing effect at costs of sharpness. Low = less combing.


Deinterlacer -> -> Motion Adaptive Settings -> Interpolator:


Basically controls how the "bob" portion of the MA is calculated. The bob is either taken from the line above, line below or the average of the upper and lower lines BFI. It's a matter of preference. I think either Top or Bottom interpolator looks a little sharper. Average is softer In the end it doesn't matter too much because Bob is only used during motion when it is hard to see detail anwyays


Deinterlacer -> Motion Adaptive Settings -> Detector:


This is a little complicated to explain... but let me try basically symmetric adds one frame of lag but the motion detection may be better. Because it is looking "one field into the future" idk if its really better tho in real life


HDMI® -> BFI Control


-Strobe: How much the frame is divided down (i.e. 1 = divide by 2, 2 = divide by 3, 3 = divide by 4) from input to output -Blur: How many frames are ON vs OFF. So let's say we are converting 60 Hz -> 240 Hz. Blur = 1, ON, OFF, OFF, OFF. Blur = 2 is ON, ON, OFF, OFF -LCD Saver - inverts the pattern of the BFI to avoid renetion. But every few minutes u will see a flicker

User Guides

The User Guides section contains guides on how to accomplish a desired task that may require the use of multiple RetroTINK-4K functions, or are applicable to multiple systems.

Defeating Dithering

Dithering is a technique many games used in tandem with the blurring effect of a video cable (like Composite) and a CRT. The idea is that the video cable and display blend the dither patterns together, to accomplish tricks like transparency or higher color depth. When using high-quality cables like RGB-SCART and Component, dithering can become very apparent, and many users may find them unsightly. The RetroTINK-4K has an option that can help:

  • Go to Advanced Settings > Processing / Effects, then set Hori. Kernel and Vert. Kernel to "Bilinear Soft" as needed. This blurs the edges of the pixels to disguise the dithering.

The cost of applying this effect is that the image will of course be rather blurry. Adding some scanlines (also in the Processing / Effects menu) can help alleviate this somewhat; don't forget that HDR will help brighten the image back up. If the dithering is only vertical stripes (like the waterfalls in Sonic the Hedgehog or the water in Kirby's Dream Land 3), you could alternately use Bilinear Sharp on the Hori. Kernel, for a slightly sharper appearance.

Sonic the Hedgehog - Bilinear Soft Vert. and Hori.

Custom CRT Masks

The RT4K allows for the use of custom CRT mask overlays via the Masks menu. This is primarily intended to give an effect similar to CRT shadow, slot and aperture masks that stretch across the screen (as opposed to scanlines, which affect the picture underneath). The RT4K uses mask images and tiles them across the screen to replicate the effect.

If you want to make your own CRT Mask, here's what you need to know:

  • Custom CRT Masks must be saved as 32-bit .BMP files.
  • The maximum dimensions of a CRT Mask image is 16 x 16 pixels. They can be smaller, which will result in denser tiling of the mask across the screen.
  • A color value of 128 will be neutral,while 0 will completely black out the corresponding pixel. 255 will double the input value (although this will be clamped).
  • Custom CRT Mask images should be stored in the "mask" folder on the SD card.

CRT masks will NOT adhere to the pixel grid like the RT4K's scanlines will. If you want them to adhere to the pixel grid, you'll need to have your shadow mask image match the dimensions of a single upscaled pixel, but this will vary depending on many factors, and so should be paired with a specific Profile you have in mind. Since Mask images have a maximum size of 16x16 pixels, this inherently means that the upscaled pixels of the input image cannot exceed 16x16 pixels in RT4K's output resolution.

Downscaling (pre-scale) Basics

Downscaling is the act of taking a picture that's one size and reducing it to a lower resolution. This process is essential for applying thicker scanlines to a high resolution image.

  • IMPORTANT: Downscaling is different from the process of having the RetroTINK-4K output a resolution lower than the source. That can be accomplished with a custom Output Resolution modeline.

For HDMI® sources, this will be handled in Advanced Settings > HDMI® Receiver Setup. Input Pixels determines how much the signal is "divided" by (with the number in brackets marking the effective vertical resolution). Output pixels also does something, I've heard. Initial Phase adjusts which pixels "survive" the division.
