Windows 10: Windows 11 won’t extend on second monitor.

I tried to setup a second monitor for my pc so that I could do multiple things at once. But I can’t get it to extend and do different things on each monitor.I can’t go to the settings and click extend but when I click off of them it doesn’t save.

Extend Display to second and third monitors

Hi Ian,



Thank you for writing to Microsoft Community Forums.



I appreciate the efforts taken by you in resolving the issue. I understand that you are unable to extend the display to second or third monitor. I’ll certainly assist you with the issue.



However, it would be great if you can help us with the details requested below:

• What happens when you try to extend the display?
  
• Do you receive any error message/code?
  
• Are you aware of any changes made to the computer recently?
  
• Which build version of Windows 10 is installed on the computer? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  
• What is the make and model of the laptop?
  

Ideally, to extend the display we can use the shortcut Windows logo key + P, and select
Extend from the menu.



I would suggest you to refer the troubleshooting steps mentioned in the article

Troubleshoot external monitor connections in Windows 10 and see if that helps.



For additional information, see
Set up dual monitors on Windows 10.



Let us know the results.

Windows 11 - How do I extend to a second monitor and then share the second screen on a projector?

I have a laptop with windows 11. I am trying to extend my screen onto a second monitor and duplicate that monitor to a projection screen (3 screens essentially). I have an HDMI converter to Serial port and a serial splitter to go between the second monitor and the projector. When I first turn the computer on, the screen is extended between the laptop and the projector (even with the monitor plugged in). If I unplug the projector screen and unplug/replug the HDMI in the computer, it extends to the monitor. I can then plug the projector back in and the 2nd monitor is displayed on the projector screen (THIS IS WHAT I WANT). The problem is, as soon as I shut down my computer or let it go to sleep, it reverts to pairing with the projector screen and the second monitor stays asleep. Does anyone have a fix for this? Can I make my second screen priority so that when the computer wakes up it extends to it and not the projector?
