I use ArgullCMS via displcalGUI. This with colormunki calibration. The monitor is Dell U2410 I go steps 2 thru 4 carefully adjusting OSD, but I cannot get "black point" correctly, if I do then "white point" is bad. It's like catch 22. Am I doing something wrong? I don't know how to use command line with Argyll. Thank you! -- AAK
