I say ThankYou for your advices and explanations. Things are much clearer for me now.
Yes, it´s the monitor, which make the problems. I calibrated another monitor, an Acer X193W and generated an icc-profile with argyll. Now I have nice colors and a blue, which looks like blue and not like purple.
I´m using cm since more than one year now. And I realized this problem two three weeks ago. So I think, the Benq-monitor has got a defekt (My moherboard and my grafikcard crashed at this time...)
Thanks for help Edgar
