As per my part of the tasks I investigated what Gnome/GTK does
- GTK is also based on 1x, 2x, 4x scaling.
- gnome have a setting in gsettings
https://github.com/GNOME/gsettings-desktop-schemas/blob/master/schemas/org.gnome.desktop.interface.gschema.xml.in.in
A settings of 0 means determine automatically which is the default which is
done inside the app. From my testing the manual setting didn't seem to
work.
The automatic detection is as follows:
"The threshold is 192 ppi, and it only works for internal panels — if it's
on an HDMI connection then it won't be considered for hidpi purposes, to
avoid broken displays that report stupid sizes like 8cm by 5cm" - Emmanuele
Bassi
There is no GUI to manually set the scaling.
