Do you find any problem with text being too small? I am typing this right now on a on a 30" 2560x1600 display which is right at 100dpi which I find is very readable. In the past I had tried 27" displays at 2560x1440 which has a dpi of 108 which made things just small enough to be hard to read. Obviously I could scale stuff in the OS, but that typically left me with some UI elements looking fuzzy/distorted. My ideal I think would be a 29" 5k monitor, so that probably is never going to happen.
