I picked up a couple of these when they first rolled around on Woot. I liked them. I picked up two more today, because I gave one to my wife, and I don't like mismatching.
(I did have one die within two weeks, but AOC replaced it, no fuss)
I don't know if I'd recommend them for professional photo/video, though, as I see a halo around the edge of the display.
As for the lack of HDMI inputs...it has DVI. A decent HDMI/DVI costs less than five bucks, and works perfectly.
