Still liking this monitor alot, still messing with fonts but I would have to do that with any 4K monitor this size.
Looks wonderful, very bright rich colors, black IS black.
NO dead pixels.
I'm very nearsighted and do not need glasses while using a computer but that makes me very sensitive to pixel size, I hate to see the individual pixels and with this monitor I have to get close and strain to see them.
Downloaded the latest version of Kerbal Space Program for Linux and run it in a window at 2560 x 1600, it runs very smoothly.
I am using the default AMDGPU video driver that was installed when I installed Ubuntu 18.04.1 and have excellent performance, the video card is a RX 580 8 GB.
I have downloaded the AMDGPU-PRO driver but have not installed it yet because the AMDGPU is working great so far.
So far VERY pleased with this spur of the moment purchase.
Also I just realized I have not touched a single setting on the monitor at all.
For me its perfect, cheap 4k, no dead pixels, vibrant colors.
