A new headset from HP has just been released. A lot of new headsets are coming and have studied the different ones according to specs etc. My choice this time went for the HP Reverb Pro. You can see my review here
Remember to add the timer key in the registration database:
The Mixed Reality Portal has an idle timer that is used to prevent Screen burn-in on Mixed Reality Headsets. By default, this timer is set to 15 minutes (900,000 milliseconds). Physically moving the Mixed Reality Headset should result in this timer being reset. If you keep the Headset still for the duration of this timer, then Mixed Reality Portal will go idle, causing the Headset to go into a lower power mode where the display is turned off.
The registry key that overrides the timer value is at:
Data The Mixed Reality Portal idle timer specified in milliseconds
Mine is now 36 000 000
