They were unable to correct problem.

no dead pixels, no problems whatsoever and the color is clean and crisp - we watch all our movies on this now... connected it to my Mac Mini (1920 X 1200) with the Display Port - and to my surveillance cameras (2560 X 1440) with the HDMI 1.4 port (Apple Display only had Display Port)

I wouldn't recommend this monitor unless Samsung corrects the problem with the sleep mode issue.

No dead pixels, no problems, the backlit is equal when black.

The problem is that when using display port connections which is the only way you can get 2K res, the monitor will randomly lose video (or sync).

My existing DVI cable did not work well, but the cable supplied by Samsung worked great.-------------------------------------------------------------------------------------------------Update: I am lowering this review to 4 stars because I am having problems with the integrated USB Hub being unstable

This problem was also present in other games like Skyrim, Dying light and Far Cry 4.

Monitor returned but still does not work (same problem).

The "worst" of the reviews claimed delta e of 2.0, which is indistinguishable to the eye (though the IPS they compared it to was 0.4).
