Hi Team,

Good day!

I would like to know how to get monitor's current scale value applied (150% or 125% or 175% or 100%).

So that i will resize the length of the window based on current scale value.

 

Appreciate if anyone provide insight on this.

 

Thanks

Hi Rajesh  ;

  I would suggest trying the "GetDpiForMonitor" MS-Windows API ...

As mentioned in the Remarks section of the documentation at this link, a DPI unaware app will always return the default system values of X=96 dpi and Y=96 dpi (100% X/Y scaling).
