Windows 10: Fixing a sudden change in monitor display resolution.

Have two identical monitors. Both had resolution set at 1280x768. Suddenly the display resolution on one of them has changed to 1024x768 and only offers one other resolution, 800x600. Why does that happen and how can I change that resolution back to 1280x768?

Display Resolution for two monitor have different settings

Hi,

Thank you for writing to Microsoft Community Forums.

The display resolution depends on the monitors that you have plugged into your computer. The display resolution modes will vary with each display based on the video card device, monitor size, video driver, and monitor driver.
By default, Windows chooses the best display settings for your PC based on your monitor, so it is recommended to set the screen resolution of the display to the (Recommended) native resolution to get the best display on your monitor.

To have better clarity on the issue, let us know the model numbers of your monitors, so that we can provide you the exact display resolution which is recommended to your monitors.

Meanwhile, try the below methods and see if this helps.

Changing the Display Resolution from Settings.

Step 1: Right Click on an empty space on the desktop and click on
Display Settings.

Step 2: In the
Display Settings window, scroll down and click on 'Advanced display settings' option under
Multiple displays.

Step 3: Then, click on
Display adapter properties for Display 1, Display 2, or
Display 3; whichever monitor you want to change the resolution for.

Step 4: Once the Display properties pops-up, click on 'List All Modes' option.

Step 5: Select a display mode that you want for the selected display and click on
OK.

Step 6: Then, click on
Apply and OK for the changes to take effect.

If these steps don't work, try reinstalling the driver by opening
Device Manager, right-click on the monitor drivers, and select
Uninstall. Restart your PC and Windows will attempt to reinstall the drivers.

Hope it helps.

 

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.
