oops i copy pasted the wrong example.
tya99 at host:~ $ export QT_SCREEN_SCALE_FACTORS=eDP1=2;DP1=1
tya99 at host:~ $ env |grep QT_SCREEN_SCALE_FACTOR
seems DP1=1 lost it's setting. I have noticed when using
xf86-intel-video displays are eDP1 and DP1 and when using modesetting
they're eDP-1 and DP-1.
