I bought this 6K monitor, but I did not like
1) The scaling on macOS. Everything was way too big. There were not enough options for fractional scaling.
2) The matte finish. I came from another matte Dell monitor, but the whole screen looked slightly fuzzy, like a permanent oil stain all over the monitor.
3) The contrast sucks. They call it 'IPS Black' but I was not impressed. The colors look different depending on the angle. This is probably an issue with the size of the monitor as well, as when you look at the left size, the angle to the right size is pretty big.
Lastly I did not like the size either, but I will have that with every 31.5 inch monitor.
