I have an ASRock z370 Gaming-ITX/ac Motherboard.
Running Ubuntu 16.04
Unfortunately I am not 100% sure which Intel Graphics Chips it has.
I do not have a secondary Graphic card I want to use Intel HD.
It is meant to be 4K capable.
Motherboard has DP, HDMI, USB-C
It currently works on 4K from the Display Port.
But HDMI does not work, nor can I get Multiple monitor to work
I installed the Intel Graphics Update Tool for Linux*, and ran it, this is what enabled the 4K monitor to work at the correct resolution through the Display Port only.
However HDMI and Multiple Monitor do not work.
Can someone advise what steps need to be taken to setup multiple monitor ?
