easy. in the osm the second item is a color palette. it has the subitems "magic color" set it to off, color tone is set to normal color control: leave all at 50 and gamma is set to Mode2. that way i get a whitepoint of 5500, and a gamma of 2.2. if you are aiming at fifferent values other settings og gamma and colotone may be better. use dispread -r to find out.

What I did was to use Custom, setBrightness and Contrast, Color Controls for R, G, and B, and I chose oneof the 3 choices for Gamma. I don't remember the details, but I did that while trying to follow the argyll instructions for calibrating/profiling a monitor. I don't see anyway to just turn offthe `advanced display settings'. I don't remember the details of what Idid, but presumably much of it I need not have done.I did calibration om mine and got fine enough results with a simple matrix profile. harald hugenschmidt Am 28.11.2008 um 23:28 schrieb Markku Kolkka:Leonard Evens kirjoitti viestissään (lähetysaika perjantai, 28. marraskuuta 2008):I have a Samsung 226CW LCD monitor. I am a bit confused about how it works. I understand from Real World Color Management that LCDs (with rare exceptions) can only control the screen brightness and the other controls, including color controls, are done using the `video LUT'. If I understand correctly, that term refers to a table stored in my video card. Does the monitor have its own LUT which is used to `calibrate' the monitor?There's one LUT in the monitor that's set by the screen controls and another in the video card that's set by the calibration data from the display's ICC profile. Some high-end displays allow loading the monitor LUT with the calibration data from the computer but AFAIK that's only possible with proprietary software in Windows or MacOS. -- Markku Kolkka markku.kolkka@xxxxxx
