The most common broadcasted HDTV resolutions are 720p (mostly for sports) and 1080i. 1080p would be nicer, but requires too much bandwidth currently. Most HDTV consumer products are less than 1080i/p, for instance projectors are most often 720p.

LCD/Plasma TVs are quite often 1366x768 which is a widescreen resolution of the PC resolution 1024x768 and kinda maps to 720p.
