I use 2 Benq BL3201PT for a few months now (side by side), I like them. Pixel pitch is still usable without HiDPI mode, and there is a lot of real estate.<p>The screen itself has very nice reviews, and I understand why; it's well made, has a nice external control panel with presets etc..<p>I do have a couple of 'nags' tho; it /requires/ a very good quality DP cable to work. The miniDP won't cut it, it's quite hard to get a 'lock' with the miniDP. Of course with DVI and HDMI you don't get 60p so it's not really a choice.<p>Also, there are occasional tiny glitches where a half of one screen will 'blink' for a fraction of a second (like, a frame) -- it's very very rare, like once every 3 or 4 days for both my screens, but it's noticeable. I suspect borderline clocking.<p>But overall, zero bad pixels, very nice colors, external control panel, excellent connectivity and it was the cheapest of the 'big' 4K's I could find, so I'm not complaining :-)
