Summary: Overall excellent. I'm not a video professional so can't attest to the technical quality, but it looks better than most I've seen, and although there's some backlight bleed I don't consciously notice as I do with other displays. Biggest complaint and only reason I'm giving 4 stars instead of 5 are the touch-sensitive buttons on the front (I have these dumb things on three different Samsung devices now).
Summary: Love the screen, and that's mostly what you buy this for of course...but I've bought similar ones from Samsung in the past and the newer ones have far less quality stands. They just seem cheap.
Summary: Great, sharp picture. Colors are vivid. Low power consumption. The backlight is powerful compare to other LED monitor, but it can be adjusted for your usage type. The power button is hard to find, but I let the monitor on because it does not use more power on standby or turned off.
