Is there any visible difference between 2k 24 and 4k 27?

Question

Monitors

I'm talking about the apparent clarity

Answer 1

Rather invisible. At 4K 27'', you will fidget around the screen with a magnifying glass like an Asian from memes.
I have 33'' 2K, highly recommended.

Answer 2

It's hard not to notice the 3 inch difference

Answer 3

Go to the store and test your eyesight, everyone's eyesight is different.
Everything will depend not only on the resolution and diagonal, but also on the matrix, size and pixel density.
If you answer from my own experience ...
Optimally I took
for\from 1080p everything up to 24 '
for\ from 2k everything from 24' to 30'
for\from 4k I think I would take at least 35 .. well, kamon, why TV?
