During setup, when I reach the step that says, "Continue in your VR headset", I am unable to continue because my headset does not work. When I put on the headset, I cannot see anything displaying; all I can hear is the sound of a fireplace (audio works). I noticed a yellow light inside the headset. Also, the setup gave me check marks for each USB 3.0 and HDMI cable. I have tried using an HDMI to DVI adapter, but it did not work. I have an Nvidia GTX780 and I have made sure my HDMI cable is plugged into my graphics card. Why is my headset not displaying anything? Please help me! Thank you so much!
