I just updated my windows 7 I5-6500 w 1070 card to windows 10 actually Microsoft tech did it as my digital license wouldn't work. Anyhow it ended up being a custom install of 1803. Now the Windows VR portal works fine and plays the MS store VR games ok. However It does not detect the HP headset in Steam VR. I have uninstalled and reinstalled Steam VR to no avail. I have no clue what is wrong here. There is something mentioned about turning off screen mirror. I don't quite know what that is but it stops headsets from being detected? Anyone out there have this problem? Any help is appreciated..
