Whats a component cable?
A Component cable splits the signal into three parts to send picture information: luminance, and a two-part chrominance pair. This connection is also referred to as YPbPr, or YCbCr. These cables are usually colored red, green and blue to facilitate hookup. But here we reach an important distinction in the input/output discussion: standard component inputs versus HD component inputs. These use the same component cables, but the results are very different.
Red/blue/green/white/red, as opposed to red/white/yellow. Component cables allow the Wii to display in 480p, which is vital if you have an HDTV. Without component cables, the Wii will look terrible on an HDTV. If you dont have an HDTV though, you dont need to worry about component cables. However, if your TV has component input (look for Red/blue/green colored holes), component cables will give you a slightly better picture.
