2560x1440 doesn't even require HiDPI support really. Just increasing the font sizes is enough. The Ubuntu Unity desktop has abstracted away that in a single slider for a long time. Apparently the next GNOME version is going to go all the way and do non-integer scaling of controls as well but in my experience that's just a small benefit, just tweaking up the font sizes is more than enough.
