In my experience, manufacturers have been labelling as "HDTV" anything whose native resolution is higher than 480p. I would expect, however, that a proper HDTV set should scale everything it receives up to 1920x1080. It's a pain, though, that there's no easy scaling to convert 1280x720 to 1920x1080... why couldn't they have set the standards as integer multiples of each other? It seems as though they chose 1.5 multiples which makes things harier for scalers.

Another thing that confuses me. We've had computer monitors for years that can display resolutions higher than 1920x1080, and prices on those have fallen through the floor lately; especially CRTs. Why, then, is it so hard and so expensive to produce TVs with higher than 640x480 resolution? Why not just slap a TV tuner on a 19" monitor and call it a TV?
