There are times when you upgrade or install Windows 10 on an old computer and the Aspect Ratio of the screen is in a mess. This issue occurs when a new Windows version does not support the GPU or the driver does not work in Windows 10. And in such cases, Windows uses a generic driver which does not support all the resolution as well as the correct aspect ratio. So in this post, you will be guided on how you can fix the issues with the screen aspect ratio in Windows 10. It could be that your screen has an aspect ratio of 16:9 but after the upgrade, you changed to screen resolution, and is now set to 16:!0. And later on, you found that you are unable to go back to the previous aspect ratio. Thus, you will notice that everything on the screen might look stretched. You might be wondering if it’s possible to change the aspect ratio in Windows 10 directly even if the GPU does not have the compatible driver, well it really isn’t. However there is another way to resolve the problem. Refer to the options given below to get started.

Option 1 – Try using the Compatibility Mode

The first thing you can do is to run the driver in a Compatibility Mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 2 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

Option 3 – Update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

The only option given when you encounter this error is to click on the OK button and nothing else and then the setup gets interrupted and won’t push through. To fix this error and proceed with the installation, you can try to get a new installation image or switch ports, or fix the CFG file. For more details, follow each one of the potential fixes provided below.

Option 1 – Try to get a new installation image

It is possible that there might be some issues with the installation image. It could be corrupted or was modified illegally. Or it could be that the bootable storage device created might have damaged sectors or installation. To resolve this problem, you need to download a fresh copy of the Windows 10 installation image using the Windows Media Creation tool or simply use the ISO image separately and then build a bootable USB.

Option 2 – Try to switch Ports

The error might be caused by the connection to the USB port. It could be that the port is unstable due to a number of factors that resulted in the interruption of the installation process. To fix this problem, you can try switching the USB port or if you are using an optical drive, you can get an external USB optical drive or connect it to another port internally and see if it fixes the problem.

Option 3 – Try to fix the CFG file

If none of the first two options worked, then you might want to fix the CFG file. This file is a configuration file format used for storing settings. All you have to do is download the CFG file. Once you’ve downloaded this file, copy this file to the root of your bootable drive and then check if it fixes the error. If not, then try to copy the same file inside the “/sources/” folder inside the root of the drive. This should fix the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
