VR Troubleshooting

Issue - HMD tracking works, as apparent by correct motion in the mirrored screens on your desktop, but the HMD screens are not on.
Quick Fix - Connect your HMD to a different video output. It seems Windows flags the screen as asleep and there is no way to wake it.
Long Fix - Make Windows forget your display states by clearing entries from your registry. Right click and delete the following and then reboot:

• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Connectivity
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\ScaleFactors
