What I do to calibrate my projector (that has very limited settings too): I
use ColorimetreHCFR to do a rough setting, to obtain a 6500K white, and a
6500K dark gray, and setting contrast and luminosity to correct values
(luminosity for black level, and contrast for white level).
Then I launch dispcal to fine tune the gamma curves, and it works great.
