Welcome to the world of uncertainties.
Stated specifics regarding picture quality, viewing angles, contrast ratio, etc are far from being cast in stone with many TV brands. One reason you can not even believe reviews, stated performance by the herds of TV gurus, and even current owners is many TV brands change or use different LCD panels during
a model year. So no matter what anyone
tells you or you read in a review from review websites and magazines, the TV you see and buy in a store may have different picture characteristics some of which may be detrimental. In other words. . . Your Mileage May Vary.
So you can possibly get some general impressions form websites, gurus, and even some AVS owner/members of a particular TV, but you need to see a TV in a store display, get the remote and tone down the settings, and judge for yourself. Note: There are even those who will tell you checking a TV out in a store is next to worthless. Believe your eyes in the store, get the TV home and road test it with proper Media Assisted Settings using a Calibration disc like AVS HD709 (Free here on AVS), and see how it performs. Always buy a new TV, not open box, and make sure the retailer has a good return policy.
My educated experience and 2 cents.
