I Almost Bought a 4K Monitor – Alex Rowe – Medium
Graphics display resolution and List of common resolutions have a big list of computer-display sizes, ranging from the teeny tiny to these sizes and larger.

I will now calculate how worthwhile this high resolution is. Normal 20/20 or 6/6 visual acuity is about 60 pixels per degree of arc ( Visual acuity), or 1 pixel per minute of arc. 4000 pixels translates into about 60 degrees across in one's field of view. That corresponds to a view distance that is close to the width of the display. So 4K width is not much improvement over 2K width, and 8K width will likely have no improvement.
Will this mean that monitors will stop at 4K?
It has a little bit of improvement, but not much. The 4K is the horizontal number of pixels, while the 1080p is the vertical number. A common resolution for 4K is 3840*2160 pixels, and a common one for 1080p is 1920*1080 pixels. Both have 16:9 aspect ratio, 16 horizontal pixels for each 9 vertical pixels. By comparison, the old VGA standard is 640*480 pixels, with an aspect ratio of 4:3.4K is the literal point of diminishing returns as far as resolution goes. That’s both my personal opinion, and my opinion as a one time official film/video person.
At one time, folks believed that 4K resolutions had enough pixels to adequately scan all the detail out of a film print, but now we’ve got 8K and 10K masters. Still, in home environments and at typical display viewing distances, it’s really hard to see a dramatic difference between 4K and 1080p. 4K is even enough pixels to project on a large screen.
