Quick hdtv question

[KNiVES]

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

No, 1080i compatibility doesn't guarentee 1080p compatibility. You may even have a screen with 1920x1080 pixels that can't display 1080p, such as the Toshiba 37WLT67. Bit of a jip really.

Most screens are currently 1366x768, and tbh you can't cram much more information into that resolution when going from a 1080i->1080p source (should it be compatible, or scaled externally).
