That's a great practical distance with great range, a foot of tolerance for the sweet spot.Īs it turns out, none of the 4k monitors really work out very well in terms of being in the sweet spot of having PPI low enough to avoid squinting and also a small enough monitor to avoid head turning. Notice that you can put a 30" monitor 20 inches away from your eyes with still hardly any head turning and it can be as far away as 30-32 inches without any squinting. That's probably my first choice at this time. The 32" 2k is not bad either, and what is currently offered. So first notice something, the 30inch cinema display, at 2k is just about as perfect as it can get in terms of balancing the two issues of minimum PPI needed to avoid squinting and maximum size to avoid head turning. Some people may tolerate more head turning and some people may have better bionic vision then me. The idea is, how close does the monitor need to be to avoid squinting and how far to avoid head turning, what is the sweet spot distance, and what is the range of that sweet spot viewing distance to avoid those problems. I got in a nerdy mood last night and put together a spreadsheet which I make no claims about scientific accuracy, but you still might appreciate it. That implies it was always a 4k monitor to begin with.


I'm really surprised to hear the 30" cinema display can do the 3840x2160.
