The LG 31MU97 is now $200 off at B&H Photo, making it $1175.
The late-2014 LG 31MU97-B 31-inch 4K display offers an attractive price, size, and form factor for a true 4K display (4096 X 2160). To use the 31MU97, a computer capable of driving a 4K display is needed. For Macs as of late 2014, that means the 2013 Mac Pro, 2014 iMac 5K or 2013/2014 MacBook Pro.
With a 4096 X 2160 resolution, I liked this display a lot. Image quality is gorgeous, particularly at a 2:1 eye-friendly display scaling of 2048 X 1080. The panel coating reminds of the NEC EA244UHD and has a very smooth but not shiny finish which makes the high resolution seem even more crisp. I prefer it to the iMac 5K display, because the iMac 5K has a mirror-like sheen.
