People who claim they cannot see any difference between 1080p and 4K screens — I just don’t believe them. It’s so insanely obvious I think they are just saying that so they don’t have to spend more money on a better monitor.

Unless you have, like, 20/100 vision the difference is like looking at a pebble and boulder and claiming they are exactly the same.

Surely people cannot be that vision-impaired and still read without glasses?
