can anyone show me the difference between 1440p vs 4k pics?

Go into a PC shop and look.

On bigger screens the higher resolution is more noticeably better.

But you need really good graphics cards to run 4K.

For desktop, any screen over 27in, for me, would get a bit hard to use (2 ft away). So 4K seems, again to me, a bit useless for a desktop PC.

Hell - I'm even happy with my 55in 1080p TV. I sit 8ft away and the resolution seems fine.
 


well the monitor im getting is an Asus ROG SWIFT its a 17inch monitor
