Summary: [SKL] monitor is not detected unless it was active
during boot
Product: DRI

I have 2 identical monitors, which have an ultrahd resolution.
On DP both work fine, on HDMI both have issues, this applies to both a native
HDMI 1.4 connection on the mainbord, as well as a built-in DP->HDMI 2.0
converter. The problem occurs both on hotplug, as well on resume from S3.
The monitor is a Samsung U24E850R.
The mainbord is a Asrock Fatal1ty Z170 Gaming-ITX/ac
The distribution is arch linux
uname -a: Linux main 4.7.4-1-ARCH #1 SMP PREEMPT Thu Sep 15 15:24:29 CEST 2016
x86_64 GNU/Linux
I will add various bits and pieces of dmesg output as comments.
