They seem to be getting better and better for PC usage. I recall early 4k units lacking HDMI 2.0 therefore being stuck on 30hz and/or difficulty getting 4:4:4 chroma sub-sampling.
Picked up a 40" Samsung KU7000 a few days ago based on this thread for KU6400 (same panel) with many apparently happy owners and was surprised at how solid it is for PC usage. My dream PC monitor would probably be the LG 38UC99 (38") ultra-wide with 3840x1600 res... but.... $1400.
Found that some people getting good results with ultra-wide custom 21:9 res and thats what I did (3840x1620). Frankly was having a bit of a hard time with regular 4k res due to the height of the 40" TV. Had to move my head to look up at upper parts of the screen which seemed quite distant from the eye level parts. Solved this by removing the stand and wall mounting it to be suspended about 2cm above desktop which also moved it a few inches further back. And the 21:9 res further lowered the viewing area. Pretty darn impressed with the results. Calibrated it with colorimeter to get 6500k, 148 cd/m2 brightness, 2.2 gamma, 4000:1 contrast ratio.
Tried FO4, Crysis 1, ROTR (all basically maxed out on GTX 1070 with little to no AA) no so far and pretty satisfied with the performance, as its less taxing than full 4k (about 25% less pixels). IQ is fantastic with 1:1 scaling. First VA panel I own and impressed, viewing angles not very good (surprised VA used on a TV), but no issues from viewing straight on from chair.
