Hello Emmanuel, > I have tried to use adaptive and hires modes of the colormunki.

There is no general problem with the Colormunki and to bright dark tones. If I had to decide, I would say, my dark tones are (if anything) a little to dark. ;-) > Do I miss something in the use of colormunki? You should definitely try to set a better matching whitepoint with the monitor controls in the dispcalGUi calibration stage. And there is always the possibility to try the original Colormunki software, to have a third result to compare. Regards, Juergen
