Significance of a Component Cable
A component cable allows a video signal to be broken into green, red, and blue signals (YPbPr). This reproduces an image that is closer to what was intended by the image's creator.
The Wii and Component Video
The Wii's component cables allow gamers to experience a deeper, richer and cleaner display on any television monitor that supports component video input.
Progressive Scan Capability
Wii component cables allow games that are capable of progressive scan to look sharper and more detailed on a progressive scan television. Both the game and the television must support progressive scan.
Using Component Cables on the Wii
In order to display the deeper and richer colors available through a component cable, you must set your Wii's television resolution settings to "ED or HDTV."
Misconceptions of Wii Component Cables
While component cables support high-definition signals up to 1080p, the Wii does not support high-definition output. Therefore, even if you have the fanciest HDTV, the Wii will only output 480p video resolution, which is not HD.
