Windows 10: Laptop Display cannot be detected

I am using Windows 11 and have a dual display setup - an external monitor and my laptop monitor. I have both enabled but decided to use PC only display .I used PC only display for almost a year, but now the laptop display cannot be detected anymore, and it won't let me extend my display.I even tried to "detect" from the display settings, and the laptop cannot detect its own display. How can I make the "extend display"?

Laptop display does not detect itself

Hi,

In regards to your concern, since the second screen can't detect the display settings of your other laptop, we suggest that you perform the steps below and see if it helps:

• Go to Settings.
• Click on System.
• Under System, choose Display.
• Under Multiple displays, click on Duplicate these displays and apply.

Let us know the details so we could further help.

 

Laptop display does not detect itself

Hi,

I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

So when I follow your steps, this is what happens:

• Go to Settings. (Done)
• Click on System. (Done)
• Under System, choose Display. (Done)
• Under Multiple displays, click on Duplicate these displays and apply. (Done)
• But then I undock my laptop and redock. Re-login, etc.
• Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.
