At this point, I could just expand on that last point and specify that all fixed-pixel display TVs--all microdisplay rear-projection and all flat-panels--always display everything at their native resolution, which is all they can display. On a 720p TV, that means that all incoming video is displayed at 720p (or 768p, as the case may be); on a 1080p TV, all incoming video is displayed at 1080p. The process of converting resolution is called scaling--sometimes called upconverting or downconverting. A related factor is de-interlacing (see point number 8, below). How well a TV does or does not handle both of these processes is a big factor in how desirable it is--and something that casual shoppers often overlook, since, compared to the screen size or resolution, it's not as easy to show as a spec sheet bullet point.
