Solved: Can’t Adjust Screen Resolution in Window

If you can’t adjust screen resolution in Windows after a Windows update or a driver update, or it happened suddenly when you played a game, this post will help you solve the issue. It appears to be a common issue where the screen stops at the lowest resolution or the setting is greyed out, making it impossible to modify in Windows 11/10.

Why Can You Not Change the Screen Resolution in Windows?

The most common reason for this issue is faulty driver settings. When drivers are incompatible, they may select a lower resolution for safety. So, you can upgrade the graphics driver or return to an earlier version.

Also, the GPU scaling option on NIVIDA or AMD graphics cards may cause this issue. As a result, you may need to enable it. Using this capability, the image can be scaled horizontally and vertically to fit the screen. However, you should know that your drivers are the most prevalent perpetrators, and your attention should be directed to addressing this computer issue.

Are You Facing a Resolution Issue or Its Scaling?

You need to check whether your screen resolution issue might be a scaling issue. Windows 11 and 10 include a feature allowing you to resize your display. This may or may not help you resolve screen resolution problems. Test the feature to see whether it has any effect on your device.

Navigate to your desktop and right-click any blank space. Next, select Display settings from the context menu. Under Scale and layout, click on the drop-down box under Scale. Check whether the 100% (Recommended) option is selected.

Fullscreen optimization is running your video game or other application in borderless windowed mode yet taking up the entire screen. This creates the illusion that the software is operating in full-screen mode. You can stop full-screen optimizations on your Windows laptop in two ways. You can either disable it entirely or only for selected programs.

Disable optimization for all applications

You can use the Registry Editor to disable full-screen optimizations for all applications. Follow the steps given below:

  • Open Registry Editor and copy and paste the path given below:
  • Right-click on a space on the right and select New > DWORD (32-bit) value.

  1. Right-click on the application for which you wish to deactivate fullscreen optimizations.
  2. Select Properties from the context menu.
  3. Navigate to the Compatibility tab.

3] Check Multiple Display Selection

System Display Windows Resolution

Windows allows you to disable one of the displays when using a multi-monitor setup. If you have selected only one monitor and the other is disabled, you cannot change the resolution. So, check whether multiple display selection is enabled for all the monitors. If so, select each monitor individually and try to change the resolution.

4] Basic Checks

Here are some basic checks and troubleshooting you can do if none of the above methods worked. Check after each solution if you still can’t adjust screen resolution in Windows.

Install and Update the Driver

Updating the latest display drivers for your PC can help you solve the issue of not being able to adjust the screen resolution of your PC. The driver installed on your PC may not be the most recent because Windows update takes time due to compatibility checks. We recommend that you get the driver directly from the OEM website. Here is how to update the Graphics card driver.

Reinstall the Driver

If you still have screen resolution issues after installing the most recent Windows update display driver, consider reinstalling the display driver using the steps given below:

  • Open Device Manager and expand Display adapters. Next, right-click on the display driver installed on your PC. Here, it is an Intel Graphic driver. Select Uninstall device from the context menu.

Try With One Monitor

If you have multiple monitors attached to your computer, disconnect one of the monitors.  Done that; go back to Display Settings to get a list of recommended resolutions for that display, navigate to Settings > Display > Display resolutions, and click the desired resolution to save the changes.
