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).
Auto Crop
The RetroTINK-4K can automatically crop and set aspect ratio for an input if it is fed a sufficient game screen. This feature works with RGB,Component and HDMI™ sources. Auto Crop 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. |
