"You realize you can adjust that, right?"
Yes. I have seen the comparison btw 4K and 2K monitors in a computer shop. In my opinion for reading documents and web browsing 2K monitor looks better.
Also I have made some search on IPS and TN panels. It doesn't look much difference. Any suggestion or comment?
