On my desktop I have a 27" 4k monitor (3840×2160) and I'm a bit intrigued on how this resolution is not enough for a 15.6" monitor, what do I miss here?
Number queens. Same people that have such advanced vision they can see the difference between 100 and 120 fps. After a certain point, even more if you're at a safe distance from the screen, more pixels don't make different to the naked eye. But you'll never convince number queens.
Why so bitter? There is no need to call people names because they have better eyesight than yourself.
I'm thinking the same thing. I have 28" 4k monitors and my 2560x1440 14" laptop doesn't bother me I can't image complaining about 4k on a 15.6 inch.
