Display Screen Resolution changes after reboot automatically on its own in Windows 11

Do your Display settings keep reverting in Windows 11/10? This is a common issue many Windows users report – ‘Every time I start up or log out of my Windows computer, it automatically switches the screen resolution to a different from the default one‘. The problem may occur if you have enabled Advanced Performance in the Device Manager, and now even after disabling it, the problem may persist. If this problem is by any installed software, the software should be removed to see if it helps resolve the issue.

In Windows 11/10, you typically set the screen resolution via the Control Panel, as shown in this image below.

In Windows 7, you were forced to reboot to apply all the changes to the display screen resolution. In Windows 11/10/8.1/8, you are not forced to reboot your Windows PC. But if you don’t, the display changes may not be applied to all items on the screen, like, for instance, the Start Screen. So if you are facing issues after changing the screen resolution, reboot your Windows computer and see if it makes the problem go away.

Display settings keep reverting in Windows 11/10

If you find that your screen resolution keeps changing automatically on its own, after sleep or after reboot, here are a few suggestions you can try:

1. Check Graphics Drivers
2. Disable screensaver
3. Uncheck Base Video setting
4. Check Power Settings
5. Run Display Quality Troubleshooter

Screen Resolution changes after reboot automatically on its own

1] Check Graphics Drivers

Ensure that your Drivers are up-to-date. Specifically, update your Graphics Card drivers. If need be, uninstall them and fresh-install their latest downloaded version. Just because you’ve upgraded your operating system to Windows 11/10 doesn’t necessarily mean you have the most up-to-date drivers on your computer. To ensure you have the most up-to-date driver, check the driver version number and compare that with information on the developer’s Web site.

2] Disable screensaver

Disable the screensaver and see if it helps.

3] Uncheck Base Video setting

Run msconfig. Then, on the Boot Tab, ensure that the BaseVideo option is unchecked. Restart.

4] Check Power Settings

Try changing the Power Settings, to allow for Sleep Mode, when sharing media. Then, from an administrative command prompt, execute the following command:

powercfg -h on

5] Run Display Quality Troubleshooter

Try the Windows Display Quality Troubleshooter.

Using Sysinternals ProcessMonitor I found that Windows was accessing the following Registry path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration

My system had three entries:

• DELF003YY7707BR0MUL_30_07D7_6A^9A3774EB79DEE3E3E38496CC7DF4D936

• QHD32000001_31_07D6_D5^63E1ABDD175E7871DCAEB710418A0F75

• SIMULATED_8086_2A42_00000000_00020000_1010100^CDE365D1B3F0942F0CF38BFB8E127AB4

Under each is a tree called “00” two of the keys are:

• PrimSurfSize.cx
• PrimSurfSize.cy

Under “00” was another branch also called “00” two of the keys are:

• ActiveSize.cx
• ActiveSize.cy

The first two of the configs (ie DELF003YY7707BR0MUL & QHD32000001) the above keys were 1440×900 – so they were not involved.

The third (SIMULATED) was set to 1024×768.

I changed these to 1600×900 and the problem was solved.

Further, I changed the resolution (via Control Panel) to 1920×1080. The moving/resize issue returned, but the lower right corner was set to 1600×900, ie the SIMULATED… settings.

Why does my monitor settings keep resetting?

Monitor settings often reset due to outdated firmware, which can be fixed by downloading the latest updates from the manufacturer’s website. Additionally, check your monitor’s on-screen display (OSD) settings for power or display options that might revert to defaults. Adjust these settings to ensure they’re saved correctly.

How do I stop Windows from changing display settings?

Ensure your graphics drivers are current to prevent Windows from automatically changing display settings. Navigate to ‘Device Manager’, expand ‘Display adapters’, right-click your graphics card, and select ‘Update driver’. Additionally, check for malware with trusted antivirus software, as it can sometimes cause unexpected changes in system settings.
