&nbsp;setGlobalScaleFactor description says&nbsp;

**&nbsp;Sets a global scale factor to be used for all desktop windows.  
&nbsp;\>\>\> &nbsp; &nbsp; Setting this will also scale the monitor sizes that are returned by getDisplays().**  
&nbsp;

Is there away to get the real physical number of pixels, independent&nbsp;from scale-factor?

Because, i&nbsp;want to set the scale factor that the virtual width is 400 px, so in need the physical size.

Also how is display rotating (90 degrees?) is handled, will full-screen-windows automatic re-sized to fit, i remember on android (with scale factor \>1) it won't be re-sized.
