well x= red and y = green, no ?
No.
I should ignore the realtime measures and only do as said with the R++ G-- B+ instructions ?
That's the best way to proceed. You should see the DE decline as you get closer to the target white.
but sometimes B is higher than the "ideal" measure to reach and it still says "B+" ?!
How do you known that ?
let me rephrase "If I lower the green contrast on my DLP projector , then "y"
> increases in the ARGYLL precalibration measures ?!" As so it might. x = X/(X+Y+Z), y = Y/(X+Y+Z) where X,Y, and Z are the measured CIE standard observer values.
my projector has no setting for the primaries, only brightness/contrast for R/G/B
Hmm. Awkward. You need to get some rough idea what brightness and contrast actually do. It could be that if it's a CRT projector that contrast sets the maximum level (the gain), and brightness sets the offset, in which case you should probably set the black point first (using R/G/B brightness), and then white point (using R/G/B contrast). You may need to go around a couple of times. But if it's an LCD or the controls don't operate normally, you'll have to figure it out for your self. Graeme Gill.
