Windows 10: Mirror One Display Laptop on One Monitor and Extend the Other Monitor.

I have a work laptop and 2 monitors. I want one monitor to mirror my laptop since the screen is bigger and the other monitor to extend the screen. How can this be done and what cords are necessary?

Windows 10 will not detect second monitor and just mirrors the display

Hi

My son has a gaming pc with a new NVidia video card and running Windows 10 I believe and we have just purchased an ultra wide gaming monitor for his birthday.

He wishes to keep his AOC existing monitor and have 2 monitors up and running and to extend the display and not mirror.

We have connected both via HDMI using I think the term is a HDMI splitter purchased from Amazon.

We have updated the Nvidia drivers as suggested and ensured all the cables are connected but when we go to Settings and additional display it does not detect the second monitor and the display is mirrored with no option to extend.

Searched on the web for half a day with no real suggestions. I use 2 monitors at work without issue so cannot explain to him why it will not detect the 2nd display.

Any help would be greatly appreciated. Thanks.

 

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.
