I have connected my Wii to a video matrix which sends all signals from my DVD, Cable Box, and Wii to an overhead projector depending upon which selection is made. When I select the Wii the picture is there, but it is in black and white with plenty of lines, etc on the screen. Looks kind of like an old analog TV signal back in the day. Any ideas? I am using composite cables, but have component if necessary. Just didn't think the nature of this problem would be solved by a cable change. Thanks for your help!!!!!!!!!!!
