rear projection tvs come in two flavors now crt or lcd, anyone know the advantage of lcd over crt?

when i am at a store comparing the two the lcd looks more pixellated than the crt, that is if i am standing really close

CRT is my choice.

If any, there's no permanent burn-in with LCD. LCD doesn't need to be converged, the geometry should stay good. Several negatives, though. Black levels for one.

Black levels is my biggest negativo.

X, you have an Elite 510HD right? I've been looking at the 630HD, and downloaded the manual a few days ago. From what I see, the convergence settings are pretty basic and easy, as well as a lot of other pro setup features. Have you looked at the 530HD or 630HD and seen any features you like?

I haven't physically looked at other models since I got mine. Two reasons:

1) They're hard to find in a showroom, I'd have to go out of my way to find one on display. They're usually not well calibrated in a showroom anyway. The original 510 I looked at was atrocious and it was a highend store. They even had SVM up all the way for DVD input. But playing around with the controls, I saw what the set could do.

2) I don't need to create that want in myself. I'm perfectly happy with mine and have no desire to upgrade. Actually, I'm not sure that the x20 series was actually an upgrade. The x30 does seem to be.

However, I read up on them. The x30 series seems to be very, very nice. 2 DVI inputs (would be nice for me as I run mine off an HTPC which has DVI out, I'm "forced" to use VGA->VGA ), 2 VGA inputs (eliminates the need for a switchbox for HTPC and HDTV inputs), an anti-reflective protective screen (I had to remove mine due to glare), and additional picture adjustments such as gamma. It also appears they fixed the s-video input problem of the x20s.

I really like the 72 point convergence, although it takes a while to do the first time. And you have to converge each input as it saves the settings by input. However, over 2+ years I've barely ever had to tweak the convergence, it stays essentially perfect.

no burn in for lcd? so you can play console games on it without the fear of burning in an image

what kind of maintenance is needed on a rear projection lcd tv?

Actually there is no burn in with either LCD and DLP. They both use lamps and they have a life span of about 5000-10000 hours. The bulbs for the DLP, if you can find one now, is about $250, do not know what a LCD bulb goes for. I really like the looks of the DLP better than any of the LCDs I have seen.

dlp is generally considered better than lcd...but it is really subjective as some people can see rainbows on dlp sets. there are a few models out now by samsung and panasonic but expect to see a lot more in the coming months.
