The Nintendo Wii does not support high definition resolutions (1080p, 1080i, 720p). It comes standard with composite cables (yellow for video, red and white for audio) that only support 480i standard definition resolution. However, with the use of component cables (red, green, and blue for video; red and white for audio) the Wii can output 480p enhanced definition resolution (EDTV). This typically results in a smoother, cleaner, brighter, more vivid picture. For people with a Wii hooked up to an HDTV, component cables should provide a noticeable improvement in image quality.
