Using Asus MR HMD in combination with the HPZ VR backpack

When removing the external screen from the PC to use the backpack, the Asus MR HMD fails to work. When I plug back the external screen the Asus HMD pops straight back in and I can enjoy VR.

When the HMD is simply plugged in whilst the PC is in the dockingstation everything works perfectly fine.

Is there a solution to this problem because this hinders the exact reason I am developing for this device.

With kind regards,

Natan Prins

Tried connecting different ways

  • External screen via docking station (HMD MR works)
  • External screen via minidisplay port whilst being out of the docking station (HMD MR works)
  • Only HMD connected to Backpack PC (with multiple powersupply) (Not working)

Conclusion: Windows MR headset permanently needs an external screen for mirroring?

    Hi @Natan_PMG You cannot pull the plug for the main desktop monitor, because the monitor graphics card HDMI need a monitor, the monitor is part of the circuitry.

    The way round this is to connect an HDMI to VGA adapter

    The VGA output is static, that means its unaffected by removal of the VGA monitor no sensors.

    So the Audio output is a 3mm plug

    Which every way you must turn the Active HDMI into Passive output to a VGA cable to monitor.

    So you pull the VGA cable the mirror software cannot detect removal of the desktop monitor and carries on the headset still works, because the desktop and graphics HDMI ports are not hunting for a HDMI monitor!

    This appears to work on an HP WMR works and when you pull out the all the VGA monitor cable the HP WMR headset carries on working.

    You don't need to worry about screen size as on desktop will always be 1920 x 1080 or less

  • You may want to try a Display Port or Mini Display Port Display Emulator dongle.

  • @Natan_PMG, did you tried the distance you can walk with the backpack? Can you freely walk 100m2 (~1070 ft2)?
