When I select Input 1 on the TV set, it flashes a brief message that it is running at 480P resolution. Is this normal for my setup? I have no idea what sort of resolutions TV sets use, but 480 seems low compared to my LCD computer monitor which is running 1680 x 1050. Or is this an apples and oranges comparison?
480p sounds right for a component source (Tivo) that is non HD. (720x)480p is also the resolution of DVDs. NTSC resolutions were lower, but tend to get bumped up to at least 480i
HD resolutions are 1280x720p, 1920x1080i and 1920x1080p, though your TV will only show one of these if it is being fed an HD or upscaled signal.
