    How to Turn On or Off Fix Scaling for Apps that are Blurry in Windows 10


    Starting with Windows 10 build 17063, Microsoft has made it easier for you to fix apps that become blurry if you dock/undock, RDP, or change display settings. Some desktop apps can become blurry in these scenarios. When this happens, you have to sign out and sign in to Windows to have these apps render properly. You can now instead turn on the Fix scaling for apps feature that will enable these apps to be fixed simply by re-launching them.

    Starting with Windows 10 build 18277 (19H1), Microsoft is enabling this setting by default, to help automatically address some of your scaling feedback, and reduce the number of times you see that “Fix blurry apps” notification.

    This tutorial will show you how to turn on or off to let Windows try and fix DPI scaling for apps so they are not blurry for your account in Windows 10.

    This won’t work for all desktop apps and it only improves blurry desktop apps while they’re on the main display. If you’re using multiple displays with different scale factors and running in “Extend” display mode, these apps might still be blurry on secondary displays.

    "Override system DPI" Per-app in Compatibility Mode Settings


    Windows reports an unchanging DPI to legacy applications, which is set when the user first signs in to Windows. This can result in blurry applications if the DPI of the main monitor changes while the user is signed in.

    1 Open the compatibility settings for the .exe file of the app you want to change the override system DPI settings for.

    2 Click/tap on the Change high DPI settings button. (see screenshot below)

    Hello @ntd252,

    You might see if turning on ClearType may help.

    My ClearType is turn on by default and couldn't help.
    The blurry text in my photos shows that it's because of the blur problem in Windows 10. I'm just tired about it. I have to set my screen to 100% scale instead of 125% to solve it and strain my eye to see things.

    If you have build 17692 or higher installed, you could use "Make text bigger" for at least text.

    You could also try a lower screen resolution to make thinks larger to see if it's blurry.

    There is only one solution that works: Back to Windows 8 scaling.

    In the Advanced Scaling settings windows type in your custom scaling size: like 125 for 125%
    Log off and on to see the effect.

    In the registry:

    HKEY_CURRENT_USER\Control Panel\Desktop
    Win8DpiScaling dword 0x1
    LogPixels dword 0x78 (is 120 i.e. nearly 125)

    Cheers
