I have a Sony HDTV (a 1080i one, not the newer 1080p ones). When I play DVDs or HD cable, the tv automatically picks up on the 1080i and 16:9 signal and changes the screen that way.
When I select 480p (i have component cables to the wii), and 16:9 format on the wii screen settings, the tv does not pick up on it. The screen changes from 480i to 480p, depending on what resolution I choose on the wii but it doesn't change from 4:3 to 16:9 when I choose the widescreen (16:9) format.
Any ideas? I saw the sentence that said some tv's dont distinguish, however I'd like to know if anyone else has experienced this issue and would like also to rule out a defective wii system.
