How to Fix a Monitor that keeps changing Resolution (STEPS)

Why does my monitor keep changing resolution?

The main reason why a computer monitor keeps changing resolution is due to outdated device drivers, incorrect MSConfig settings or incorrect Windows Display settings.


  • Outdated Device Drivers
  • Msconfig Settings
  • Outdated Windows Settings
  • Hardware Issues


Outdated Device Drivers

Generally, operating systems use device drivers to send and receive instructions to and from the hardware. If the device drivers, particularly your system’s display drivers, are outdated, it can lead to this issue.


Msconfig Settings

System Configuration Utility or Msconfig is a tool you can use to configure how your device will start and what services and programs will load when Windows starts. If the Msconfig tool is set to switch back to the low resolution of the display after sleep, it can cause the resolution changing issue.


Outdated Windows Settings

Regular updates will keep your device error-free if you are using Windows 10 or 11. An outdated Windows version can lead to multiple errors, including a change in the screen resolution.


Hardware Issues

If none of the above causes are present, hardware issues might lead to this problem. You can either run a troubleshooter to solve it or call the customer support team of your device and let them assist you.


How do I stop my monitor resolution from changing?
