Maybe it is "old" (from last year...) but it has HDMI 2.0, DCI P3 and even HDR 10 if you need it. I Don't know any Samsung PC monitor that is aimed at pro video editing.
The 3200 model does not support DCI P3 which is a shame for this price and the HDMI is only 1.4 verson = 30Hz.

What do you think, will it bring a real change in grading for us? Nikon confirmed that it will be 12 bit output through HDMI:
