I just bought this TV today and it looks great! One thing I have to note though is that you must play games and do work at a distance! the light from the screen can be a bit tasking on the eyes, but that comes with the territory. The image quality is superb, even at 1080p, watching 4k videos on YouTube is really quite amazing! If anything it makes the 1080p videos pale in comparison, that may be some downscaling tech from the TV itself or from the GPU [AMD Radeon 7790 OC to 1200mhz].
Another thing my wife literally just noticed is that it does seem a bit dark at about a 35-30 degree angle, but again, this is not a home theatre screen so you can't expect great viewing angles. At the price it is marked, mine today was 219.99 at best buy, it is a good deal, and I have looked online to find similar deals and they are either the same price for a similar quality unit or higher price for higher quality. Just FYI this display replaced my 6 year old Dynex 27" @ 720p Monitor (which cost a hilarious $400+ when I bought it). Skyrim looks amazing, BF: Bad Company 2, GTA 4, and several others looks great too, definitely a smart buy!
