New Plasma: 1080p or 750?

I agree a quality 1080i/720p at a viewing distance up to 10' will look just as good as good 1080p. I bought a Pioneer Elite at a good discount when the 1080p's were just hitting and am hard pressed to see the difference when I see a 1080p. But when I get BluRay that may change.
I would say always invest a future proof as you can and get the 1080p anyway. I'd hate to deal with any regrets down the road.

Right, I meant 720 not 750. Hmmmn, I've heard others say the same thing that, you can't really see the differnce between 1080p and 720 on a 42". but I really am not that in to tv and don't see a need for anything bigger. but just for arguments sake, how big of a tv do you need to see the difference between 1080 and 720?

But are you into films? Blu-ray into a 1080p display enables you to have a picture quality at home that exceeds the movie theater, and is sharp along the line of a full-resolution IMAX presentation.

In other words, if you see a 1080p Blu-ray feeding a 50" or larger 1080p display, you may change your mind about how important it is.

To answer your question, I think 42" is right on the cusp. With a Blu-ray 50GB source you'll notice the difference with a 47" display and definitely notice the difference with a 50" or larger.

All my life I've wanted to be able to afford the theater experience at home. Blu-ray into 1080p exceeds it.

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.

If your going to watch Blue Ray movies and play games get 1080p LCD and get the fastest refresh rate you can afford. Be very AWARE of the GLARE issues with Plasma if it is going to be in a room with multiple windows.
