I have a 42" Panasonic ED plasma. My Dish 811 HDTV receiver puts out 480P, 720P, and 1080i - 720P isn't viewable, but the 480p and 1080i are. Since the plasma isn't technically capable of displaying 1080i, I'm wondering how I can view 1080i and why, it seems, looks better than 480p - perhaps thats my imagination though. Anybody have any insight into this? Do I risk damage by pushing 1080i into it? Thanks.
