I have a Sanyo XP21N which has a 1040x768 LCD panel. When I plug my Dish 6000 tuner into it with a VGA cable it never fills the screen vertically and only wide broadcasts fill it horizontally. It looks correct for the wide broadcast but 4x3 images have large borders on ALL sides. On HD signal, the proj shows 1080i detected. Is something wrong with either of the units?
