After buying 2 28"-4k Korean monitors on the cheap. I decided to instead spend my money on a good brand with good features that has contrast and color calibration and the whole 9 yards. This time I went with an LG 27UD88
. There is also a similar model the 27UD68 that is $200 cheaper without color calibration. I feel color calibration was a good investment for an IPS monitor when I do some digital artwork. This one will run me about the same price as the 2 Korean Monitors did. I can't wait to hook it up.
The reason I am not going to keep my Korean 4k monitors is they are a bit finicky. The contrast ratio and viewing angle is a bit annoying. They run a bit dark. They don't have freesync. Getting the color to appear correctly takes some work. They have problems running at 60hz with my GPU.
