Colormunki Display and dispcalGUI + Argyll CMS

[munkidsp SourceForge]

Hey there,
First of all thank you for your developing effort and sharing with us your software solution.

I’ve started this thread to find some answers about the properly way to set up and calibrate a PC monitor, using the Colormunki Display device, dispcalGUI / Argyll CMS software solution.

What I’ve done;
Pre-calibration phase:
-I’ve installed Argyll LibUSB/Eye-One Display Driver (Argyll);
-Reset to default the Video Graphic card in display driver settings;
-Reset to default the monitor settings;
-Restore defaults/ Reset video card gamma table;
-I’ve made a report using Tools / Report on uncalibrated display device function in dispcalGUI to see the gamma, white / black level values;

At this phase, before we proceed I am interested to know:
-which way of lighting is the best to calibrate a monitor: total dark environment or the regular room light condition (not necessarily daylight source)? I’ve read different point of views and I’m confused, that’s why I am asking.

-If I use Tools / Import colorimeter corrections for Colormunki Display device, should I notice somwhere in the correction section, the imported profile? there is no such a profile in the dropdown menu.

-Whitepoint; There are a lot of options; Settings as measured, by Color temperature 5000-6000K;
According to the dispcalgui documentation, If you want to find out the current uncalibrated whitepoint of your display, you can run “Report on uncalibrated display device” from the “Tools” menu to measure it. In the report, I have the following values:
White Correlated Color Temperature = 5364K, DE 2K to locus = 9.5
White Correlated Daylight Temperature = 5366K, DE 2K to locus = 5.9
White Visual Color Temperature = 5130K, DE 2K to locus = 9.2
White Visual Daylight Temperature = 5237K, DE 2K to locus = 5.6
What value should I use, in which conditions?

-White level = 149.82 cd/m^2 the measured uncalibrated monitor value (?)
-Black level as measured (?) as long as I don’t want to match two different screens with different native blacks to one another OR the measured uncalibrated monitor value 0.1103 cd/m^2 (?);
-Tone curve – I suppose 2.43 the measured uncalibrated monitor value (?)
-Ambient light level adjustement – If I am working in different light level environment, I suppose that this is useless in my case am I right?

Thank you,
