> I would suggest to try using different DisplayPort cable. It has nothing to do with the cable. I've had this issue on every single 4K monitor I've used with these laptops - which is at least three different monitors, with different cables - and it even manifests with HDMI 4K output (at 30Hz). All of these setups work perfectly fine with my XPS 13 running at 4K on Linux. I don't understand why you think that the OS's inability to scale the system UI or applications in a reasonable way would have anything to do with the cable. Try it with a Linux laptop running Unity, and you'll see the difference.

Because that's not the experience everyone else is having. That leaves possibility, that something is broken on your end. > Try it with a Linux laptop running Unity, and you'll see the difference. I know how Linux handles HiDPI. See my comment about Fedora elsewhere in the thread.
