Change the display scale for an individual application

Question

Hi,

Windows 11.

I have an old application which does not scale itself. I need it to scale to 125% to be readable -- the font it uses is too small.

What I'd want:

Set Windows scale at 100%

Set the application at 125%

However, I can't seem to find a way to do that. The Properties -> Compatibility -> Change high DPI setting can only go with either system or application.

Is there a way to change the scale of an individual application to scale up?

Thanks

Answer 1

I'm looking for the reverse.

For most of application, I'd want to it to scale itself. I'd want to set the system at 100%

For this old application use very small font, I'd want it to go to 125% or higher. The above approach can only force the application to use system scale which is 100%.

Hello redhonker

Welcome to Microsoft Community.

Regarding to your information I assume that you can't see the old application words because the font is too small.

It may caused by compatibility conflicts between old software and new systems. You can use this feature "High DPI scaling overrider" to fix this

problem.

Follow these steps turn on this feature.

Find the .exe file of your old application-> right-click this icon-> click Compatibility-> click Change high DPI settings-> select High DPI scaling

overrider->select System (Enhanced)->click OK.

Run the old application check your problem fix or not.

If there is anything not clear, please do not hesitate to let me know.
