I am happy to announce...

HDTVs are most definitely sharper. However, since TVs are much larger than monitors, the pixels are larger (they have to be), and therefore are slightly less well-defined. The fuzziness is slight no matter what type of HDTV you have, but projections are the fuzziest, followed by CRTs and then LCD/Plasma TVs (no fuzzy at ALL).

Some (not all) HDTVs support high resolution. 480p is standard, but there are also 720p and 1080i. It's a toss which is actually better. I'd pick 720p... though in all honesty there is very little that truly supports high-res on a TV.
