Depends on how you use it. If you pull Apple's trick with retina displays (or an equivalent mode in other OSes) then no, to the user it'll appear the same as a 1920x1080 display, but with crisper text. The point is that pixels are supposed to be invisible, so in the theoretical ideal future, everything would be resolution independent so that decreasing pixel size doesn't make the display unreadable.
