dispcal asks me to measure strange things

[Дмитрий Мышков]

When I calibrate the monitor, the program offers me to adjust the white point and black point.
I adjust the white point (RGB), but when I go to the black point, I see that the color needs to be reconfigured and so on ad infinitum.
I have no settings for the white point and black point (about color) for the monitor, but only three osd RGB sliders (about color).

Do I need to run back and forth and reconfigure and something will eventually happen?
Or is this program designed for expensive monitors and in that case I need to use the standard software, for example i1profiler? That is, software for inexpensive monitors?
Can anyone explain? Please. I’m not good with opensource software and I have Windows. not Linux etc.

You are doing a LCD monitor?    Not sure why but white point matters and not black on LCD.    Display Cal screen type should be LCD if a LCD and then the option for black point adjustment will not be there.  This is on the main screen , first page on the left.    It is designed for all monitors.    You have to set it up for the monitor type with the display mode and the meters correction for the screen type.   Display Cal is better than I1profiler because it has a lot more options and no software limits based on what meter you bought or your license.

Thanks, Ben.
I think I figured out what the problem was.  I had the “generic” update mode, but I should have set it to “lcd”. Now I work only on the white point.

Yes, but
-only if your display has RGB gain & offset controls (both)
-only till you get to a solution of compromise. Whetever you cannot correct in whitepoint will be corrected in GPU LUTs. It’s likely that even with RGB offset controls you cannot fix black point by OSD tweak.

Displaycal + argyllCMS can capture behavior + calibrate any monitor, bad behaved or good behaved. i1Profiler has more limitations in terms of colorimeter correction to new backlight technologies and in the patches read to calibrate greyscale (some bad behaved monitors with severe color tint in uncalibrated greyscale may not be corrected win i1Profiler).

Both Xrite i1Profiler/CalibriteProfiler and ArgyllCMS calibrate using GPU LUTs, plus additional whitepoint & white level tweak on OSD by user.

Some monitors have HW calibration, user writable LUTs inside monitor. You’ll need monitor manufacturer software or 3rd party app with specific protocol comunication to write them. i1Profiler/CalibriteProfiler and ArgyllCMS do not have this functionality.

Can anyone explain? Please. I’m not good with opensource software and I have Windows. not Linux etc.
