Wii:Video Output Notes

To get the highest quality video from an unmodified Wii, you can use component video cables as they'll support 240p, 480i and 480p (provided your display supports all three resolutions). There also exists a VGA output mod and two intensive mods to add an HDMI port and improve the stock component video quality. You may see Wii2HDMI dongles out there, they negatively affect the video signal in their conversion of component to HDMI and it's recommended to avoid them.
