When I Choose extend to desktop to the hmd everything works fine, the oculus screen turns on, the resolution is set. But on the configuration utility it says that there is "NO HMD DETECTED, Tracker Connected" and the games also do not recognize that there is a HMD, so I am not being able to utilize the rift. I am using the DK2, i have already updated all of my softwares and I have already reinstalled the oculus utility and drivers and still nothing. I have also switched usb drives from 2.0 to 3.0, turned the headset on and off and still nothing. I am considering formating my pc which is currently 8.1 to maybe windows 7. If anyone can help at all I will be very thankful.
