The new LCD's are the way to go, though they only go up to about 32" right now. Run coooler, quieter (no fans!), more reliable and have a better picture. A little more expensive but in the same ballpark. I'm hoping the 42 inchers will be out by Christmas.
I know the High Definition plasma screens I saw about a year ago couldn't reproduce black 'to save their lives.'
It was funny because the demo video was emphasizing all the things it couldn't do very well like track motion and it suffered in dynamic range ... especially in shadows being brighter than what you'd see on a CRT.
Just bring a dynamic test DVD and pay attention to how it renders shadow detail and take note of the color of the shadows.
Check the viewing angle to be sure you're happy with that. I think they're up to at least at 130 or 160 degrees now.
That's a nice TV
But a bit too thick for us since we have to put it up above the mixing/composing workstation (on the wall).
Since the Plasma sound like they're still a little dodgy wrt accurate resolution, how do the LCD TV's compare to Plasma?
