Hi, so recently I bought 2 Radeon VIIs to put them into my PC with the plan in mind to connect one to my monitors and use it to game while the other one mines 24/7 on nicehash. When I‘m not using my PC I want to use both.

So, the problem I‘ve stumbled over is that the VIIs don‘t put out any signal to my monitors over HDMI. However, if I replace one VII with my old 480 it works. Is there any chance that my motherboard doesn‘t support these cards? I have an Asrock H87M Pro 4 with 2 pcie lanes. Did any of you encounter similar problems?
