I know that the Wii doesn't formally support HD, but it does have at least 480p resolution. Yesterday I got a new HDTV (first one) and decided to hook my Wii up to it. While I managed to get the 16:9 resolution to work, everything looks really blocky and pixelated. When I go into the Wii settings and try to change my TV type to HD instead of standard, it won't let me select it. Is there a particular cable type that needs to be used for this? Or is it a problem with my TV? I'm hooking the Wii up with the standard composite cables that come with it.
