Fixing applications that are blurry on Windows 10

56
If you have multiple screens connected to your computer or if your display configuration has changed, some applications may be blurry. Windows 10 (version 1803 or later) can try to fix this problem automatically so your apps won’t be blurred. Windows can’t fail to repair all apps, so some apps will remain blurry on high-res screens.

Here are some examples of when this could happen:

  • You can open the app on a high-definition screen and then move the app to another screen that has a different resolution.
  • You dock your laptop or tablet to a screen that has a different resolution, then use Second Screen Only mode .
  • You are remotely connecting to another computer and the display you are connecting to has a different resolution than your device.

Comments: 

  • To use the setting to automatically troubleshoot application blur, you must be running Windows 10 (version 1803). To find out which version of Windows you are using, see Which Windows operating system is using my computer?
  • If Windows 10 (version 1903) is installed, the setting to resolve blurry applications is turned on by default. However, this feature can be turned off at any time. The notification for fixing app blur is app dependent and may still be displayed.

Automatically fix application blur

If your apps are blurry or if a notification about blurry apps appears on the main screen, do the following:

  1. Do one of the following, depending on whether you get the „Fix blurry apps?” Prompt:
    • If prompted, select Yes, open the settings , and then select Apply .
    • If the prompt is not displayed, enter advanced scaling settings in the search box on the taskbar and select Repair blurry applications. 
  2. Under Troubleshoot applications, turn on Let Windows repair applications so that they are not blurry .

To determine if Windows can fix this problem, close the desktop application that is blurry on the main screen, and then restart it.

If the app is still blurry, you can try using a different high definition compatibility setting for that app instead of the Let Windows repair the app window so that it isn’t a blurry setting. For more information on how to do this, see Create legacy programs that are compatible with this version of Windows .

Enable or disable manual app blur repair

Whether there is an issue with blurry apps or there are blurry app notifications, you can turn the feature on or off at any time.

  1. In the search box on the taskbar, type Advanced Scaling Settings and select Fix Blurred Applications .  
  2. Under Application Troubleshooting, Enable or Disable Allow Windows to try repairing the application so it is not blurry .
Turn on or off notifications about blurry apps

While notifications about automatically fixing app blur can be useful, they can sometimes be redundant. Here are two ways to turn off notifications:  

  • Select the Start button, and then select Settingssystem notifications & actions, then turn off Display Settings .
  • Select an action centerand then Focus . This feature of Windows 10 allows you to manage the display of notifications. For more info, see Turn on or off focus in Windows 10 .
