What to do if Windows 10 changes resolution by itself
- Deselect the Base Video Option
- Clean Boot Windows
- Roll Back Graphics Card Driver Update
- Reinstall the Graphics Card Driver
- Restore Windows to an Earlier Date
The Windows 10 resolution setting doesn’t usually reconfigure itself. Yet, some users have said that their VDUs’ resolutions change from the default setting whenever they start Windows. After adjusting the display resolution to a higher setting, it then drop downs to a lower resolution after the users restart Windows. It is a somewhat baffling issue that arises for some users.
Why did my Screen Resolution Suddenly Change?
The resolution changing can often be due to incompatible or corrupted graphics card drivers and the Base video option. In addition, conflicting third-party software might adjust the resolution. This is how you can fix the resolution in Windows 10 when it automatically changes.
1. Deselect the Base Video Option
The Base video option starts Windows in a minimal VGA graphics mode. That is certainly an option that can have an impact on your laptop’s or desktop’s resolution. Thus, deselecting the Base video setting is a potential fix for the display resolution. You can deselect the Base video setting as follows.
- Press the Windows key + X to open the Win + X menu in Windows 10.
- Click Run on the menu to open that accessory.
- Enter ‘msconfig’ in Run, and click the OK button.
- Then click the Boot tab on the System Configuration window.
- Deselect the Base video check box.
- Press the Apply button to confirm the new settings.
- Click OK to close the window.
- Restart windows after closing System Configuration.
2. Clean Boot Windows
Conflicting third-party software can also be another factor behind the frequently changing resolution. So a clean boot, which starts Windows without superfluous startup programs and third-party services, might also fix the display resolution. Follow the guidelines below to clean boot Windows 10.
- Open Run with the Windows key + R hotkey.
- Input ‘msconfig’ in Run and click OK to open System Configuration.
- Click the Selective startup radio button on the General tab.
- Deselect the Load startup items check box.
- Select the Load system services and Use original boot configuration options as shown directly below.
- Select the Services tab shown in the snapshot directly below.
- Click the Hide all Microsoft services option.
- Press the Disable all button.
- Select the Apply option, and press the OK button.
- Then select the Restart option on the System Configuration window that opens.
3. Roll Back Graphics Card Driver Update
Some users have fixed variable resolutions in Windows by rolling back graphics card driver updates. So reversing a recent graphics card update might also fix the issue on your desktop or laptop. This is how you can roll back a video card driver update in Win 10.
- Press the Windows key + R to launch Run.
- Then input ‘devmgmt.msc’ in Run and click OK to open Device Manager.
- Double-click Display adapters to expand that category.
- Right-click your video card and select Properties to open the window in the image directly below.
- Then press the Roll Back Driver button on the Driver tab .

4. Reinstall the Graphics Card Driver
If the Roll Back Driver button is grayed out, you can still reinstall the video card driver. The graphics card driver might be corrupted, so reinstalling it is another potential fix. This is how you can reinstall a video card driver in Windows.
- Open the Device Manager window.
- Expand the Display adapters category.
- Right-click your video card and select the Uninstall device option.
- Select the Delete the driver software for this device option on the Uninstall Device dialog box.
- Press the Uninstall button.
- Windows will automatically reinstall a video card driver when you restart the desktop or laptop. However, if you prefer, you can still manually download the latest video card driver from the manufacturer’s website and install it as covered in this article.
5. Restore Windows to an Earlier Date
Restoring Windows to a previous date with System Restore will remove third-party software installed after a selected date that might conflict with the display resolution. Rolling Windows 10 back to a restore point might also roll back a video card driver update, which can also fix the changing display resolution. You can roll back Win 10 with System Restore as follows.
- Open Run with the Windows key + R hotkey.
- Input ‘rstrui’ in Run’s text box and press Enter to open System Restore.
- Click the Choose a different restore point radio option, and press the Next button.
- Select the Show more restore points check box so that the window includes all restore points.
- Select a listed restore point, and press the Next button.
- Press the Finish button to confirm your selected restore point and roll back the OS.
Those are some of the fixes users have fixed the display resolution with. In addition to those fixes, turning off the screen saver and fast startup mode might also resolve the issue.
