Iv been gaming on my PC at 4k/60hz on my 55inch TV.. i was thinking of buying a monitor but not sure if going from 4k to 1440p is going to be a noticable difference in a downgrade.
I heard 1440p is a very good resolution from 1080p to 1440p.. but what if you are use to 4k going down to 1440p?
The jump is like going from 720P to 1080P... Which is because 2560x1440 (1440P) is 4x the resolution of 720P and 3840x2160 (4k) is 4x the resolution of 1080P, so it's the exact same relative jump.
But whether you will notice a step down from 4k? Well. That depends on panel size, viewing distance, eye quality and so on.
On a 27" display, the difference between 1440P and 4k is probably not going to be as pronounced as a 55" TV that's for sure, all about the perceived pixels per inch though.
