Trying to set up Oculus Rift headset to a new Alienware machine that is compatible with OR headset. When installing headset, I am able to get audio through the headphones, but do not get video. The OR software just says "adjust your focus", but that's it..there's no video coming through headset. When I plug in the HDMI end of the headset into the computer using a DVI adaptor, the computer reads the headset, and you can see the headset in the devices manager page. BUT..the screen starts blinking and there I'm still not able to get the headset to show images. Again, the computer has all the requirements necessary for the OR headset. Just not getting any video, but I do get audio. And when the headset is connected using a DVI adaptor, the headset monitor shows up in the devices list, but I don't get video, and the computer screen blinks. Any help would be greatly appreciated.
