(2021 Fix) Apps are Blurry on Windows 10

App blurry issues can occur when you use a single monitor, but it’s more common occurring to multiple monitors. This issue can occur in the following scenarios:

  • Use a higher resolution monitor
  • Setup multiple monitors
  • Move app between two monitors

What causes the app blurry issue?

When you run into app blurry issues in Windows 10, you’re probably using a high-DPI (Dots Per Inch) monitor and the applications are written without DPI awareness.

Windows default DPI is 96 PPI. But for most monitors, their DPI is higher than 96 PPI (Higher DPI means higher resolution which can provide higher quality picture). Fortunately, Windows offers DPI scaling support. When a high-DPI monitor is connected, Windows will automatically set a right DPI scaling level to ensure all elements like the app look fine.

For example, in the screenshot below, the DPI scaling level is set to 125% (recommended), which works for many high-DPI monitors.

However, many applications are written without taking the DPI of displays into account. Once a DPI scaling level is applied, the app, fonts and other elements will be scaled. This can make some elements bigger but blurry. If the applications are written without DPI-awareness, they can also become bigger but blurry. For more details about application DPI-aware, you can check this link.

Fortunately, Windows allows us to configure high DPI settings to fix the app blurry issues. Move on to know how to do it.


Try these methods to fix app blurry issues

Method 1: Change high DPI settings for the applications
Method 2: Enable Let Windows try to fix app so they’re not blurry
Method 3: Set a custom DPI level for your display


Method 1: Change high DPI settings for the applications

As mentioned above, when Windows sets a DPI scaling level to make elements look good on a high-DPI display, some apps can become blurry. To fix the blurry issue, you can change high DPI settings for applications.

To do so:

1) On your keyboard, press Win+S (the Windows logo key and the S key) at the same time to open search.

2) Type the application query into the search box, and then right-click on the application name and select Open file location. I take ‘Chrome browser’ as an example in the following screenshot.

3) Right-click on the application shortcut and select Properties.

4) Select the Compatibility tab, and then click Change high DPI settings.

5) Select the Override high DPI scaling behavior. Scaling performed by: check box, then select Application from the drop-down menu.

select_override_high_dpi_scaling_behavior

6) Click OK -> OK to apply the changes.

7) Check to see if the app blurry issue persists. If the issue persists, try to log out of Windows then log in to make the changes apply. Before logging out of Windows, be sure you’ve saved everything you need.

If multiple apps have the blurry issue, repeat the above steps to fix the problem for each app.

Method 1 will probably solve your app blurry issue. But If it doesn’t work for you , move on to try other two methods.


Method 2: Enable Let Windows try to fix app so they’re not blurry

To fix the blurry issue, you can turn on the ‘Let Windows try to fix app so they’re not blurry’ option to allow Windows automatically fix the issue. Here’s how to do it:

1) Right-click on the desktop and select Display settings.

open_display_settings

2) Scroll down to find and click on Advanced scaling settings.

select_advanced_scaling_settings

3) Click the toggle button under Let Windows try to fix app so they’re not blurry to turn it on.

4) Close the window and check to see if the app blurry issue is resolved. If the problem persists, try Method 3.


Method 3: Set a custom DPI level for your display

Setting a custom DPI level has been confirmed by some Windows 10 users. You can try this method too. Refer to the following steps to set a custom DPI level for your display.

1) Right-click on the desktop and select Display settings.

open_display_settings

2) In the Scale and Layout section, under Change the size of text, app,and other items, you’ll see the current scale level your system is using. Mark it down so you can use it later. For example, in the screenshot below, the current scale level is 125%.

3) Click on Advanced scaling settings.

select_advanced_scaling_settings

4) In the Custom scaling section, enter the current scaling size (the size you marked down in Step 2)) in the ‘Enter a custom scaling size between 100% – 500%’.

enter_current_scaling_size

5) Click Sign out now to make the change apply. The opened apps, folders and documents will be closed after you sign out. Before signing out, be sure you’ve saved everything you need.
