I plugged my htc vive vr device to the graphic card hdmi and shows nothing, so seems the hdmi port doesnt work. I just have a dvi monitor, no hdmi so i cant test it with a monitor or tv, just with the vive device. I read that there should be an hdmi port in the display adaptar in windows devices but i just see the graphic card. I have the latest drivers installed, i reinstalled them twice. I see there is a hdmi audio device detected in windows but dont know if hdmi display works.
