One Monitor running on a 2 monitor display, cant disable the second monitor. Help?

Hi,

If you can't access the Display settings, it means that it appears on the second monitor which you don't have. This happens if Windows is not back to the primary desktop.

We found an article similar with your concern. We suggest following the troubleshooting steps provided by SpiritX MS MVP on this

thread. It will guide you on how to disable the second display.

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.

Dual monitors

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to use Dual monitors on the computer after updating Radeon software. I’ll certainly assist you with the issue.



However, please let us know:

• Do you see the second monitor detected when you go to Display Settings?
  
• Which build version of Windows 10 is installed on the computer? Refer
  Which version of Windows operating system am I running?
  
• What is the Make and model of the computer?
  

If you do not see the second monitor in Display Settings, I would suggest you to click on Detect and see if the second monitor gets detected.



Since you are facing this issue after updating the Radeon software, you may want to try rolling back the driver and see if that helps.



To do this, refer the steps mentioned below:

1. Press Windows key + X, and select Device Manager.
2. Expand Display adapters.
3. Right click on the Radeon Driver and select Properties.
4. Navigate to the Driver tab and click on Roll Back Driver.
5. Restart the computer if prompted.

Let us know the results. If the issue persists, we will certainly assist you further.
