Recently got a new HDTV, which can display 1080i on my Xbox 360. What I'm wondering about is why it can't display 1080p? When I try to set it to 1080p, the screen just goes all funny, with a shade of green. I thought that if a TV could display interlaced 1080, it could also do the progressive version too? Could somebody try to explain things to me, I'm new to all this hdtv stuff
