it was assumed that a human eye can barely discern pixels of 900PPI at 1feet away, which means the theoretical limit at 3feet is 300PPI.
Seating distance is different for everyone. I typically sit around 3ft, but at times it can be from 2ft to around 5. It just depends. I feel that having a PPI that will allow you to comfortably read and view things at various distances is what's really important. You also have to factor in how good your eyevision is. If you're nearsighted, then you'll have to sit closer than someone who is 20/20, who will be able to sit farther while seeing the same amount of detail.
A 27" 1080p can be a "retina" screen, you just have to adjust your seating distance while compensating for your eyevision.
For me, 55" 4K is sublime. It's definitely the most comfortable and immersive monitor I've ever used. You all can play with you're little 24" toys
