I was unable to find any API for getting the make or model of the monitor.
Someone who is more familiar with XCB could give the authoritative answer

If this is indeed impossible then users with multiple monitor setups have
to manually maintain multiple QT_SCREEN_SCALE_FACTORS configs, based on
either screen index or connection name.
