WMR check display cable FIX

    Hi,
    I'm posting this to help others avoid the frustration with this nonsense error seen sometimes on WMR headsets.

    TLDR:
    The Fix:
    Go the registry editor, press start and type regedit, press enter to open.
    Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY
    In there find the default display folder.
    Inside that folder, there may be a parameter sub folder.
    In the subfolder, see if there is a line that starts with BAD_EDID
    If there is, delete the whole parameter folder and reboot.
    Now your HMD should be detected as a monitor by windows.

    Story:
    My Odyssey+ was working perfectly for last few months when on booting my PC up next day, suddenly the mixed reality portal displayed the error 1-4, check your display cable.

    I did everything but reinstalling windows. I uninstalled all the usb drivers, the WMR portal itself, nvidia drivers etc.

    And still it would not recognise the HMD as a display in device manager.

    A windows update was downloaded and applied, upon reboot, my HMD was working again. But after a subsequent reboot by me to check it was still working, it wasn't detected again, same error.

    So I knew my connections were ok so it was some configuration problem preventing windows detecting the HMD as a monitor.

    The Fix:
    Go the registry editor, press start and type regedit, press enter to open.
    Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY
    In there find the default display folder.
    Inside that folder, there may be a parameter sub folder.
    In the subfolder, see if there is a line that starts with BAD_EDID
    If there is, delete the whole parameter folder and reboot.
    Now your HMD should be detected as a monitor by windows.

    My PC has survived multiple reboots with this method. If the error shows up again, I will check my registry first before tackling any other troubleshooting methods.
