I've got a colleague who had the P50 4k display, who said the only annoying part at the time was that moving Chrome or IntelliJ from a lowdpi to highdpi display meant you had to relaunch those processes (and this was some time ago). While I agree this is annoying, Fedora 25 launches this month with Wayland, which is supposed to fix these issues.
