HP ENVY All-in-One - 27-b214
Microsoft Windows 11

I am trying to connect an external monitor to my HP ENVY All-in-one

 

At boot, I see the HP logo on both the displays (internal and external) but after that, the external gets black (but it appears as still connected to the desktop.

 

I tried several monitors and several cables. I've updated all drivers, uninstalled and reinstalled drivers. I reset my PC back to factory settings. The problem still exists.
