How to fix display scaling issues without signing out of Windows 10

Windows 10 adds a new settings in a new effort to fix scaling problems that cause blurry apps in certain scenarios, and here's how you can use these settings.

Fixing scaling causing blurry apps on Windows 10

Display scaling has been a problem for a long time, and even though, Windows 10 has introduced changes to prevent blurry apps as a result of incorrect scaling, it’s still a big issue, especially when using traditional desktop applications and multi-monitor setups.

In a continued effort to improve scaling, Windows 10 (version 1803) now includes a new option in the Settings app to make it easier to fix apps when they become blurry on scenarios without having to sign out. For example, when changing the display settings, running a remote session, or docking and undocking a device.

In this guide, you’ll learn the steps to use Windows 10 settings to fix scaling issues on your display.

How to fix blurry apps on Windows 10

If you have apps that don’t scale properly in certain scenarios, you can enable a feature to fix blurry apps the next time you relaunch them.

  1. Open Settings.

  2. Click on System.

  3. Click on Display.

  4. Under “Scale and layout,” click the Advanced scaling settings link.

Once you’ve completed the steps, Windows 10 will try to make sure that apps don’t look blurry the next time you open the app without having to sign out and sign back into your device.

In addition, if the system detects that you may be running a blurry app, then a toast notification will pop with an option to fix this issue when you reopen the app.

It should be noted that this feature works only for apps running in your primary display. If you’re using a multi-monitor setup with different scale factors, apps may still look blurry in secondary monitors. Furthermore, this may not work with every application.

How to fix app scaling issues individually

Alongside this new feature, Windows 10 also includes override options that allows you override the system-wide scaling settings per-application.

  1. Right-click the .exe of the app.

  2. Click on Properties.

  3. Click the Compatibility tab.

  4. Under “Settings,” click the Change high DPI settings button.

  9. Click OK.

  10. Click Apply.

  11. Click OK.

After completing the steps, even though, you may have specific global scaling settings configured on Windows 10, the app will not respond to those settings, instead it’ll use the custom settings you selected within the Compatibility settings.

If you can’t find these options, it’s likely because you’re not using the version that includes these changes. The options to fix blurry apps and override settings per-app are included with Windows 10 version 1803 (April 2018 Update), which is expected to roll out sometime in 2018.
