Asus taichi 21 back screen not working on Window 10

Mine is ASUS TAICHI 21.

When I'm using laptop mode, I can touch or scroll it by touching back screen, but I can't see anything.

When I switch mode to tablet mode and close my laptop, there's nothing to see on back screen.

You must update BIOS settings from the setup (F2).

It is a normal fault in this model which is solved in this way.

This issue is not solvable with windows 10. ASUS tichi21 has huge compatibility issues with a lot of windows 10 drivers and even updating BIOS from the ASUS website will not solve this issue. your only fix is to downgrade to windows 8 this will restore functionality to your back screen. however you will have to manually disable all windows updates as any new update (even to windows 8.1) will reintroduce your issue.

there is a BIOS update for windows 8.1 but its glitchy .. you get get this from ASUS website
