Well... to each it's own.
The 28" 4k monitors don't have enough real screen surface for me, the items are displayed way too small for my eyes.
And 1080 is "tall enough", more than that will make my head tilt up/down to cover the whole screen.
I learn a while back that straining my eyes is never a good thing, eyesight once gone, doesn't come back. But that's just my personal lesson learned.
