Spend an extra $100 and get a better TV.... Sony Wega, Panasonic Tau, Toshiba Flat.
I bought the Samsung 27" and I was very disappointed with it's performance. I ran my Video test DVD on it and found it had poor screen geometry, the screen was tilted and cut off the lower corner. The color was so-so, I noticed the colors to over saturated, more so with the reds. Adjusting the settings helped a little bit, but the problem was still noticeable. As for the picture quality... it was OK, Components helped out the color, but I stilled noticed a cleaner picture with the other brand TVs. And for the record I tested RCA Composite, S-Video, and Component... the problems occurred regardless of the cable connection.
I took the TV back to the store and just to make sure it wasn't a fluke I had the sales guy hookup a DVD player to their display model so I can run the test DVD. I returned it, paid a little more and picked up a Panasonic Tau. I was originally going to go with the Wega to match my existing 40" XBR Wega, but the salesmen hooked me up with a nice deal on the Tau.
You pay for what you get....
