   Hi, I am unable to display 4K 60HZ from hdmi jack 2 on my Fatal1ty z170 mini itx.I've updated the firmware to support HDMI 2.0.Installed drivers in order when building system.
Tested three cables, monoprice(6ft), Amazon basic high speed(6ft), twisted pairz 2.0 cable (10ft)
I have no other equipment to test 60HZ on. 4K 30HZ works fine. When I change refresh to 60HZ my screen goes blank then reads no single- times out to previous setting. 

Hardware:
Vizio M60-C3
I5 6600 3.3Ghz
Samsung m.2 
GSKILL TRIDENT 3200 16GB
Fatal1ty z170 mini itx/ac

	Same here Also did the update firmware for the hdmi, which by the way asrock needs to update the readme/pdf You can't just run the exe after extracting, i had a gtx970 installed and would get an error to shutdown the system. After some searches on google i found a post on tom's that said you had to do it without external gpu and the update finally worked BUT the actual output from the board's hdmi 2.0 port will not do 4k60 reliably, hell it won't even connect at 30hz a lot of the time after the supposed firmware update; the secondary hdmi 1.4 output on the board is ok for 4k30 I know it is not my cables or display because i have no problems when connected to the gtx970

	I am able to get connect for 4K@60hz to my Z170 itx/ac@HDMI2. It is not stable though comparing to DP1.2.
