Thank you for the answer. Iccdump shows quickly what I'm looking for even if it
should be comfortable to investigate directly the video card LUT before the
calibration process.
I have discovered that the video card gamma table of my netbook EEEPC 900 has 3
channels. At this point I doubt that still exist video cards with a single
channel.
