Re: [arch-general] xrandr with XPS 13" (3840x2160) HiDPI and 30" (2560x1600) LowDPI

As far as I understand, QT_SCREEN_SCALE_FACTORS needs an entry for each screen. The primary screen will get the first factor, then second screen the second factor, so you can try this:

QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCREEN_SCALE_FACTORS="2;2"

SUCCESS! SUCCESS! SUCCESS!! Now the font for Qt apps is correct on both screens using: xrandr --output eDP1 --scale 1x1 --mode 3840x2160 --pos 5120x0 \ --output DP1 --scale 2x2 --mode 2560x1600 --pos 0x0 https://i.imgur.com/KB5UNxy.jpg I have made a revision to the wiki to make that clear. https://wiki.archlinux.org/index.php?title=HiDPI&type=revision&diff=532206&oldid=529558 Thanks all who have helped! -- Tyler
