Extending display suddenly broke after changing resolution

Hi

Welcome to Microsoft community.

I understand the issue you're experiencing with extending your display after changing the resolution. It seems that changing the resolution to 2160p on one of the monitors that doesn't support it has caused the problem.

Here are a few steps you can try to troubleshoot and resolve the issue:

1. Disconnect both monitors from your computer and restart it.
   
   • This will help reset the display settings and clear any temporary configurations that may be causing the problem.
     
2. After the computer restarts, connect only the monitor that was set to 1080p and check if it extends properly.
   
   • This will help identify if the issue is specific to the monitor that was set to 1440p.
     
3. If the 1080p monitor extends fine, disconnect it and connect only the 1440p monitor.
   
   • Check if it extends properly on its own.
     
4. If both monitors extend fine individually, try connecting them both again and set the resolution to their respective native resolutions (1080p and 1440p).
   
   • Go to "Settings" > "System" > "Display" and make sure the resolutions are set correctly.
     
5. If the issue persists, you can try updating your graphics driver to the latest version.
   
   • Visit the website of your graphics card manufacturer and download the latest driver for your specific graphics card model. Install the driver and restart your computer.
     
6. If none of the above steps resolve the issue, you can also try performing a system restore to a point before you changed the resolution.
   
   • This will revert your system settings back to a previous state when the issue was not present. Keep in mind that this will undo any system changes made after the restore point.
