I'm a bit confused by this whole 4K, QHD, Retina thing. Basically, I've got an ASUS PB287Q 4K display that I bought earlier in the month. It's sharp and clear but not without it's problems. I'm a designer and this is my main screen and I've noticed that colours are affected by what angle I view the screen at. So, I'm thinking of returning it. Enter the LG 34UM95. I was thinking of picking this up as a replacement, but I can't tell if it's 4K or not. I basically need a monitor that is as close to Apple's retina display on the iPad as possible. 2x normal resolution, basically. Is this a good fit? Also, will I have the same viewing angle problems as the Asus? Any help is appreciated. Thanks in advance!
