Windows 10: High DPI settings for windows system dialogs

I'm using Win11, and some of system dialogs looks blurryFor other program it can be fixed in exe-file-properties->Compatibility->Change high DPI settings dialogBut for system dialogs, for instance network adapter properties, which is displayed by dllhost.exe - there is no such option.So how can I fix it ? Can I change it globally for all programs ?

:)

 

Understanding Priority of High DPI Settings Dialog

Windows 10 Pro, Version 21H1, OS build 19043.1415

In File Explorer, select an EXE file.
Open Properties | Select Compatibility tab | click "Change high DPI settings" button
The High DPI Settings dialog appears. See Left picture below.

Check the "High DPI scaling override" checkbox.
The "Scaling performed by:" has a listbox with three choices. Select one.

The dialog also has the "Program DPI" checkbox
which says "Use this setting to fix scaling problems for this program instead of the one in Settings".

If I check the "Program DPI" checkbox,
it enables the "Use the DPI that's set for my main display when" dropdown list.
Is the only function of the "Program DPI" checkbox to allow you to specify
"I signed in to Windows" or "I open this program" for the app?

Why does "Program DPI" have the link "Open Advanced scaling setting"
which takes you to the "Advanced scaling settings"? See Right picture below.
"Advanced scaling setting" are global for a display - not app specific.
Is this just a convenience so you can see the settings for "Advanced scaling setting"?

How does the "Program DPI" checkbox relate to the checked "High DPI scaling override"?

If "Program DPI" is unchecked, does Windows ignore the "Advanced scaling setting" and only use the "High DPI scaling override"?

If "Program DPI" is checked, does Windows ignore the "Advanced scaling setting", use the "Use the DPI that's set for my main display when" setting, then use the "High DPI scaling override" setting?

Thanks in advance for the feedback.

Mancy - Thank you for the response.

Does that mean the answer to my previous two questions, repeated again below, is that

(App | Properties | "Change high DPI settings" dialog) - Left picture
is independent of
(Settings | Display | "Advanced scaling settings") - Right picture?

If "Program DPI" is unchecked,
does Windows ignore the "Advanced scaling settings" and only use the "High DPI scaling override"?

If "Program DPI" is checked,
does Windows ignore the "Advanced scaling settings", use the "Use the DPI that's set for my main display when" setting, then use the "High DPI scaling override" setting?

Thanks in advance for the feedback.

 

[SOLVED] How can I get 'Change high DPI settings' to work?

===== SOLUTION =====

Go ahead and read my problem statement, but look at my second post to see the solution.

=====

Applications (a game in this case) have Property sheets.

"Properties" > _/Compatibility\_ > --Settings-- > [Change high DPI settings] opens a secondary dialog with the following controls:

Program DPI

[_] Use this setting...

[I signed in to Windows]

[I open this program]

High DPI scaling override

[_] Override high DPI...

[Application]

[System]

[System (Enhanced)]

I've tried all 12 combinations. They appear to do nothing.

I think these Property settings are meant to control graphic scaling, useful for high DPI systems. My laptop has a 3840x2160 display.

Can anyone tell me how to get 'Change high DPI settings' to work?

Warm Regards,

Mark.
