I have used Fedora 21 with 4k display for almost a year, but few weeks ago some update broke support for 4k display resolution. I'm guessing that intel driver is at fault. Have any of have also noticed this issue with 4k displays on Intel hardware or also on some other hardware? Obligatory link to bugzilla - https://bugzilla.redhat.com/show_bug.cgi?id=1238101 ps, I have Lenovo T440s with Haswell graphics.
