Built-in Screen Not Detected

Aspre E17 (E5-772G-52Q7) is not detecting the built-in screen. Connected external monitor via VGA and that works fine. Fn+F5 opens the Win10 "Project" menu, but only selection that does anything is "PC screen only". Same with Intel HD Graphics Control Panel, only detects external monitor. Any ideas? Just started happening mid-day today.

 

Thanks in advance!

    Try FN + F6. This switches the display output between the display screen, external monitor (if connected) or both. You may need to do this 3 times to cycle through the three choices. If that or FN + F5 which turns on/off the LCD back light does not resolve the issue, and you've already tested with an external monitor which worked, chances are the issue is with the mainboard or LCD and will require repair.
