I have a Vizio M3D420SR. It's a 3D TV that uses passive 3D. I went into the xbox console settings, Enabled 3D, and then turned on the 3D settings in the games that support it (Gears 3 and Black Ops), but then my TV will not recognize the xbox as a 3D enabled device. The TV has a Side by Side 3D option, which these games use, but the TV will not let me into the 3D settings when I am on the xbox. Are my TV and xbox not compatible, or are there some other settings I have to change on the xbox (The TV's 3D works fine with a certain other console I own, so the TV's not broken).
