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.

Let us know the results.

extending monitors

Hello,

I hope I can help you today

solote allow two monitors but here I leave this possible solution

Step 1

Connect a monitor to the normal video card, using the necessary cable (DVI, VGA or HDMI). This will be the main screen, so place it directly in front of your computer's cabinet.

Step 2

Connect the second monitor to the alternative port of the video card, and then restart the computer. The PC will automatically detect the second monitor.

Step 3

Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the second monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop on this screen" checkbox.

Step 4

Connect the third monitor to your original video card (if it has three outputs) or to another video card, and then restart the computer one more time.

Step 5

Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the third monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop to this screen" checkbox

regards...
