HP laptop multiple display not detected

[Melab4]

Why is my HP laptop not detecting multiple displays? It was working fine earlier today but now will not detect anything. I checked the settings function for displays and tried another computer station and the same problem.

Hi @Melab4,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand you have trouble connecting the HP Pavilion 16-inch Laptop PC 16-ag0000 (955U3AV). It was working fine earlier today, but now it will not detect anything. Sorry to hear about the issue.

Before we try any advanced troubleshooting, please remove any external devices connected to the Pc and try the BIOS restore and let me know if this helps.

BIOS Restore :
1) Shut down the computer, keep the  charger plugged in
2) Hold down the Windows and B buttons together while the computer is still turned off.  
3) Turn on the computer and continue to hold the Windows and B buttons until a BIOS Recovery screen appears.  
4) Follow the on-screen instructions and click on OK

I hope this helps.

Take care and have a good day.
