I use a 28" 4K monitor, personally, and I set it to 200% and it was actually pretty gorgeous. My only main gripe is that, while I was able to increase the size of my mouse cursor, it moves much slower in pointer mode and changing the camera speed doesn't affect that. I'm not going to switch back anytime soon, just wish I could adjust my mouse cursor speed (no, changing the DPI settings is not an option as that would mess up other things I do on the PC.)
