I guess xrandr can't do that, you'd need a different tool which supports
RandR 1.2.


FWIW, if you set one of your connected outputs as the primary with

 xrandr --output DisplayPort-[123] --primary

xcalib should work for that output I think. Not sure if its settings
will be preserved when switching the primary output though.
