Thanks for posting this. It wasn't meant to be a snarky comment, but I did leave out some basic assumptions which I thought were obvious. "Usually" the larger the screen the further away most people will sit from there screen. Right now, I'm on a 21" monitor sitting about 3'2" (already out of the 2'6" for added benefit of a 4K screen if you take this chart as gospel) from the screen. If I went up to a 28" monitor, I would most likely move it back at least 6" so that I don't have to move my head and eyes around too much. That would put the screen about 3'8" from me which is within the range of full benefit of 1080p but outside the range of 4K for this size and viewing distance.
