It has a few control on the monitor that you can change. You can
also change them via software with (g)ddccontrol, and I have created
a file for the monitor so that everything has a proper name/value.
The things you can control:
- Brightness/contrast
- Gamma from -0.6 to +0.6 in steps of 0.2
- For R, G and B you can change the level of the LED lights,
really changing the white point.
It also has some presests that change the whitepoint, but those
are just names (warm1 - warm6, cool1 - cool6).
It also has presents for sRGB and AdobeRGB, but I'm not using
that.
I do not have windows. The x-rite i1 that comes with it works
with argyll. I think they also sell it without it, in case
you already have a calibration device.
I've currently changed the brightness/contrast and R/G/B values
and stored them in a profile in gddccontrol, and then calibrated
my monitor with argyll. I should probably change the gamma on the
monitor and then do the calibration again.
It seems that video in X (with xv) does not make use of the video
card LUT.
