Windows 10: The Extended Monitor Does Not Work

Hello.This problem began with a CCLeaner run. After I performed the scan/fix, the monitorssuddenly did not display.I did a factory reset and changed both the docking station and HDMI cables. Also purchased a 1-in, 2-out StarTech HDMI splitter. These efforts enable two displays in extended mode, but only the laptopresolution is visible Integrated UHD 400not the optimal resolution for both the monitors.

Unable to extend monitor display

Hi Jay Jap,

thanks again for your reply.

I checked the screen resolution settings through windows and then through the Nvidia graphics cards.

Windows detected both monitors but Nvidia settings didn't.

I downloaded and installed the Nvidia drivers again and it's working fine. Simple solution, not sure why I had to install the drivers again? But thanks for your help, your suggestion to check if the monitors were being detected prompted me that it had to
be a graphics card issue.

 

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.
