my pimax shows a blue led and a backlit screen but screen is black and does not show anything. I have tried re-installing piplay to older version and current version but does not work.
Going by Memory you need tot go to settings then where it shows device there should be a box for display in 1080p…you must check the box. Good luck
Can you post your system config?
Piplay version & first 3 serial numbers ie 100 or 102
Also just in case the headset will stay off until the sensor between top of the lenses is blocked.
This link may help.
Also please try another USB port on your machine… Don’t use a USB hub
