Numerous factors contribute to errors, indicating there are diverse approaches to fixing them, yet no assurance exists regarding the efficacy of implementing those solutions.
This article below will guide you through some strategies to rectify this issue.
Option 1: Manual Configuration Adjustment
Although altering Display Settings directly on a Windows computer is unfeasible, an alternative solution is available for you.
Step 1: Right-click on any empty space on your desktop, then choose Display Settings.
Step 2: On this window, observe anything resembling the Custom Scale Factor is Set: error.
Do you see a gray bar? And you find yourself unable to interact with it. If you wish to modify the scale, click on the Turn off custom scaling and sign out button, then set the scale. If for some reason your computer enters hibernation or restarts, you will need to perform this action again.
In the example above, you can see the screen set to 175%.
Step 3: Next, scroll down the page and select Advanced Display Settings.
Step 4: On the following window, scroll down to find and click on the option Advanced Sizing of Text and Other Items.
Step 5: This is to take you out of the Windows settings window and into the Control Panel. The menu might seem a bit unfamiliar; here, locate and click on the link named Set a custom scaling level.
Now, a new window appears on the screen. Here, you can customize the settings for Scale. This setting exists in 2 different locations, but one of these settings is more detailed than the other.
In the dropdown menu, select a Scale setting of your choice, then click OK, and choose Apply. Everything will undergo a transformation.
Navigate to the Menu.
Finally, log out and log back in to apply the changes.

Option 2: For Laptops with Intel HD Graphics
If you're using a Windows laptop with integrated Intel HD Graphics, the Intel driver might be the culprit. Here's the solution for you.
Step 1: Right-click on any empty space on the Desktop, choose Graphics properties.
If you don't see this option, click on the system tray in the bottom right corner and look for Intel icon - a small blue icon.
Step 2: Right-click on that icon and choose Graphics Properties.
Step 3: Now, the Intel HD Graphics Panel window appears on the screen. Here, click on Display.
Step 4: Here, you'll make just one change. Find and click on Maintain Aspect Ratio at the bottom of the window, and check Override Application Settings. The final step is crucial.
Essentially, this tells the Intel driver to ignore all other settings and enforce the settings you apply for Scale.
Finally, you can close all windows and restart your computer. And the changes will take effect.
Option 3: Check for Software on the Screen
Admittedly, this solution may not be particularly different from other solutions. Mainly because users may not have much experience with it.
Similar to the Intel utility mentioned above, each manufacturer designs their own screen software. For example, LG integrates additional software for 4K screens with window management features. However, this may cause complications with the Windows display.
If your screen has custom utility installed - set up by the screen manufacturer - try uninstalling that utility.
After removing this tool's installation, proceed to restart your computer. Hopefully, everything will be resolved.
Option 4: Remove Any Third-Party Extensions
Interesting fact: DPI scaling on Windows 10 isn't exactly perfect. When setting up DPI scaling, fonts may appear blurry. As a result, a developer created a tool allowing users to switch to the scaling method of Windows 8.1 called XPExplorer.
If using this tool, you need to set the scale from within the tool, not in the regular Windows settings.
