Custom Scale Factor is set error in Windows 11/10

There is an issue with setting a custom scale factor in Windows 11/10. 

If you are on Windows 11 or 10 and trying to change the settings for Display scaling, and you get an error message, something like, "A custom scale factor is set" - try these fixes:

Update the firmware of your display and restart it.

Repair the files representative of your system

Power-ON your computer or Restart it

Explanation of all the above-mentioned fixes in detail:

One thing you can try is to disable the custom scaling.

Once you have scaled your screen to your liking, Windows will no longer present the Scale menu option, and it will display a notification "A custom scale factor is set". This notification will be turned off upon turning off custom scaling, and the Scale menu option will be once again available. See if this works.

It is preceded by the link: "Turn off custom scaling and sign out." It logs your account off. Now log in and see whether the display scaling is customizable or still the same error remains.

It is expected that this fix will be effective. Despite clicking on this link, several customers still complained that the issue persisted. If you're in a similar situation, look into alternative solutions. 

2] Update the firmware on your display and reboot it.

It might also be that your monitor has gone bad. Restart your display to check for this. It is not a problem of any setting; nor will simply restarting the monitor fix it. You have to update the firmware of your monitor. Search for the latest firmware update for your monitor and learn how to install it from the official website of the maker. Click here to go to the official website and learn how to update the firmware on your monitor.

3. Analyze the problem in Clean Boot.

Start the computer in a Clean Boot state and analyze whether you can set the scaling of the screen. First, start the computer in Clean Boot. After that, open the display settings and see whether you are able to set the scaling of the display. If you are, then the scale of the display can be set.

A problem might be in some third-party background application or service if it disappears when the computer is in the Clean Boot state. After installing this app, did you ever have the ability to change your display's resolution or scale? If yes, uninstalling the app would solve the issue. 

Step4: Reinstall driver software for your graphics card safely.

Sometimes the driver software of your graphics card can be responsible for this issue. Your graphics card driver may be outdated. If your computer has a relatively updated version of the driver software of your graphics card, then you may download it from the website of the manufacturer company. Run the setup file in order to install driver software for your graphics card. Alternatively, you can also update your GPU driver using your manufacturer's own program. You can do that through AMD Software, Intel Driver & Support Assistant, etc. 

Do a Clean Installation of the graphics card driver if that doesn't work. That will need an external application known as Display Driver Uninstaller. Run the installer. Open the DDU utility immediately after you boot into Safe Mode. Employ DDU to remove the GPU driver off your computer. Afterwards, run the setup file and perform a clean install of the driver for the graphics card. Due to GeForce Experience, cleaning installs of drivers of an NVIDIA GPU is easy. Fifth, repair system image files.

This problem can also be caused by corrupted system image files. System File Checker and the Disk Image Repair program will replace your system files. Run these utilities one after another. When the scans are finished, check if the problem has gone away .

6. Reset your computer or restore your system.

You also can roll your system back to the previous state by choosing an appropriate restoration point. Instead of having all your data deleted, you just had to bring your computer to its default settings. But first, you probably want to back up your data before restarting your computer.

An arbitrary set of scale factors is an error now in Windows 11; we hope you could make much use of that.
