Fedora 21 updates broke support for 4K displays :(

[valent.turkovic at gmail.com]

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 -

ps, I have Lenovo T440s with Haswell graphics.

Cheers.
