I've been using the environment variable QT_ENABLE_HIGHDPI_SCALING=0, which provides me a nice "maximization" of screen real estate.

My laptop display runs a 1920 x 1080 resolution, with 125% custom scaling (Windows 10).

Now I wonder, is it possible to run Calibre on a actual 1920 x 1080 resolution, bypassing the system custom scaling, so that I can get even more screen real estate?

I did some searches and found the links below, which seem to be helpful on that matter, but in doing many trial/error experimentations, with variables like QT_USE_PHYSICAL_DPI, QT_SCALE_FACTOR, QT_SCALE_FACTOR_ROUNDING_POLICY... I had no success:

https://doc.qt.io/qt-6/highdpi.html
https://superuser.com/questions/1017...nt-resolutions

Also, I set the Calibre executable "high dpi scaling override" to be performed by the application.

I probably should add, hopefully to make my question more clear, that I personally prefer general UI items/toolbars/buttons/ as small as possible, which is not the average user general preference.
