I just got my HD811 rcvr from Dish and clicked on the 1080i function on the dish menu and all 3 colors are separated. 720p is fine. Also in HDTV mode, the regular component input display for 4x3 480p leaves a ragged small black border on the left and right of the screen. SVS is fine on an alternate input. Does this mean I need a calibration, and if I do should I try to eliminate the small black border in 480p mode?
