I got a 4k 32" IPS monitor years ago and was never really happy with it for similar reasons. Scaling never felt right, 2x is like basically using 1080p and fractional never looked good or had issues (in linux). Now I have a giant curved samsung display which is like two 1440p monitors side by side. There is a new version that is like two 27" 4k monitors side by side and I am just worried I would have the same issue I had before... I kind like being able to see my pixels :)
