Hi - I'm getting sound but no display when connecting my new Rift to the HDMI port at the rear of my MSI GT83VR notebook. It's running dual GTX980 graphics cards in SLI - the Oculus app stated that it meets or exceeds the minimum requirements to use the Rift. The light in the headset is amber.
It's a USB issue. Try plugging in your sensor to another USB port. Disconnect anything that is not required and test again. You could be having a video card issue, I don't have any experience with notebook setups. When my screen was going black and the light was amber, it was either a USB issue, or my extension cable for the rift needed an HDMI repeater.

I can confirm this works, we had the same model laptop at work and the Oculus would not turn on no matter what we tried. Then we got the mini DP to HDMI 4K adapter and it works great now. Also you need to turn off sli in the nvidia control panel.
Hey, checking this thread...I have the MSI GT73vr and am having the same sort of issues? Are you saying we need an extension for the HDMI port? My screen goes to black as well? Any help would be greatly appreciated.
