A lot of people have their TVs professionally color calibrated after it is installed to ensure you are seeing what you are supposed to see in magnificent detail.

http://www.thelittleguys.com/ they KNOW their stuff, all professionals work there. They have TVs that cost more than a Porsche 911, but also reasonable ones. They are local for you too, Steve Dahl is always recommending them as they have installed all of his audio/video in his home.
HDTV with 1080p is a MUST since everything is converting to that pixel resolution. Will be great for blu-ray DVD and such when it gets rolling in the market.
Plasma is the absolute best picture/color quality. Burn-in is minimal with newer models, I still wouldn't play video games on a plasma. The cost of plasma TVs are well above LCD and DLP.
DLP is nice, the colors are true from black to RGB to white. It's sharp but not as sharp as an LCD or Plasma. There is an issue on DLP that will drive you nuts once you notice it. Trails. Before you purchase a DLP set, watch some FAST ACTION movie scenes on it. If you have good eyes, you will see a trail effect as if it's studdering on the screen. It happens VERY fast but I notice it and it drives me crazy. Major con of DLP in my opinion, but beautiful still or slow action display.
LCD is my favorite between cost savings (without having to go Plasma) and picture quality. The picture is extremely sharp (better than DLP) but the downside to LCD is true color display. It cannot display true black. You will notice when there are scenes where it "fades to black" to fade into another scene, etc, it fades to almost a dark grey. You can see the color spill-over when it fades to black. This is a minor issue in my opinion since fast action is more important than fading to black. Who is really paying attention when it fades out anyway? But it is a tad annoying.
Plasma is the ultimate, no issues unless you leave something on the screen still for hours upon hours, then it can burn in the screen and leave a ghost image of it, but the little guys told me the newer models wash out the ghost over time. Plus all plasma is true flat panel!!!!!!!!!!
