I just built my own PC from scratch. I also bought a brand new monitor and windows 10. However I can't install the monitor driver without windows 10 and I can't install windows 10 without the monitor. I am connecting the monitor via HDMI to my motherboard. Is it just that the motherboard(ASRock Z170 Pro4S) is only outputting the DVI-D, if so I will need to get a new cord but I'd like to hear if anyone knows for sure.
