From time to time, some users complain that they cannot change the screen resolution in Windows 10. Users report that the screen resolution drop-down menu does not show all available resolutions, or only shows the current screen resolution. If you can't change the screen resolution in Windows 10 either, try the solutions below.
Check if the display driver is installed on your PC
In most cases, you cannot change the screen resolution without installing the correct display driver . To check if you have installed the display driver, follow these steps:
- Access the Device Manager from the Start menu browser.
- Expand the Display adapters section.
Your graphics card entry indicates that the driver is installed. If the display driver is not installed, you will see the entry for Microsoft's basic display driver
Restart the display controller
Sometimes restarting the display driver can fix the problem. Therefore, it is a good idea to restart the display controller by simultaneously pressing the Windows + Ctrl + Shift + B keys. Your PC will beep once when restarting the display controller and the display may flicker once.
Check if you can already change the screen resolution.
Update the display driver
Windows 10 automatically downloads and installs the latest version of the display driver whenever it is available. If you have disabled automatic driver updates, you can manually check if an update is available for the display driver. Here's how to do it.
- Open Device Manager.
- Expand Display Adapters.
- Right-click the entry for your graphics card, and then click the Update Driver option.
Reinstall the display driver
If you are unable to change the screen resolution, it is most likely due to a corrupt or missing display driver . Reinstalling the display driver should fix the problem.
After reinstalling the display driver, restart your computer once and then see if you can now change the screen resolution.
