Summary: Purchased this a month ago from a big box store for 2100. I agree with some of the others that the picture out of the box is not Samsung quality. However, I purchased a Disney Blu Ray calibration disk and it solved my issue. It takes a bit to go through the calibration but the results are far better than the factory settings. Today, 03/07/2012, my daughter turned the TV on and then the HD DVR and no picture. After some coffee I attempted to investigate the issue.
Summary: Great tv, just remember to turn off the motion enhancement setting, this setting make everything look weird. For the price you can't find a better tv. Only problem is that the remote use the same frequency that my cable box remote, it get annoying, don't know how to fix that problem.
Summary: Hocked up to a pc, with a beast of an ATI video card, this tv is a disappointment. Nowhere near the picture quality of my 60" Samsung, and it only works full window at its HD native resolution. Buyer beware!
