It's a function of the screen size and viewing distance. I sit 15' away from 65" DLP RP, and I can't reliably distinguish 720p and 1080p. On a 42" display you'll need to sit real close to distinguish 720p and 1080p. I would guess no more than 5ft away.
New Plasma: 1080p or 750?
I'm breaking down and getting a new flat screen. A friend of mine suggested the Panasonic 42" Plasma with 1080P. But then he also says, most HDTV signals only broadcast in 750 and only some games and Blue Ray signal in 1080P, and that TV won't get to 1080p for years. Is that right? if so, no sense paying an extra $100 or more for a 1080P. Also, is LG as good as Panasonic? thanks
