Hi,

I purchased this board ASrock H170M PRO with Intel HD530 Support (I'm using i7 6700K) for the reason it has a Display Port 1.2 connector.

HDMI works just fine 4k @ 24Hz (limitation is stated in ASrock documentation)
Display Port isn't recognized by the monitor (The DisplayPort of the monitor works with other computers).

I have only one new amazon basics DP cable, I can't test if it is a faulty cable, because on the other computer (MacBook Pro) I'm using a miniDP to DP Cable, so no other Device with a full DP available at the moment.

In bios I set primary display adapter to integrated (not PCIe).
But HDMI works even with primary adapter set to PCIe although no Card is installed.

The only reason I bought this board is 4k@60Hz support via DisplayPort without using a PCIe.

Thank you for any suggestions.

Best
Gregor
