Hello,
I'm using ArgyllCMS V2.1.2 on Windows with ColorMunki and have strange
problem with high resolution mode.
First I'm doing
>dispcal -R
and (part of normal) response is
Measured display update delay of 73 msec, using delay of 197 msec & 0
msec inst reaction
patch 3 of 3
patch 17 of 17
patch 17 of 17
Uncalibrated response:
Black level = 0.1048 cd/m^2
50% level = 24.79 cd/m^2
White level = 85.91 cd/m^2
Aprox. gamma = 1.79
Contrast ratio = 820:1
White chromaticity coordinates 0.3325, 0.3440
White Correlated Color Temperature = 5499K, DE 2K to locus = 2.3
White Correlated Daylight Temperature = 5500K, DE 2K to locus = 2.8
White Visual Color Temperature = 5444K, DE 2K to locus = 2.2
White Visual Daylight Temperature = 5566K, DE 2K to locus = 2.7
Effective Video LUT entry depth seems to be 10 bits
The instrument can be removed from the screen.
Then I'm doing
>dispcal -R -H
and response is
, using delay of 200 msec & 0 msec inst reaction
patch 3 of 3
patch 17 of 17
Uncalibrated response:
Black level = 0.0000 cd/m^2
50% level = 0.00 cd/m^2
White level = 0.00 cd/m^2
Aprox. gamma = 1.80
Contrast ratio = 928:1
White chromaticity coordinates 0.3323, 0.3444
White Correlated Color Temperature = 5508K, DE 2K to locus = 2.7
White Correlated Daylight Temperature = 5509K, DE 2K to locus = 2.4
White Visual Color Temperature = 5443K, DE 2K to locus = 2.6
White Visual Daylight Temperature = 5564K, DE 2K to locus = 2.3
Effective Video LUT entry depth seems to be 10 bits
The instrument can be removed from the screen.
Notice that "Measured display update delay" is not displayed, also
Black/50%/White levels are all zero.
Then, during calibration in high-res I do finally get error
Doing check measurements

Commencing display calibration

dispcal: Error - Aprox. fwd matrix unexpectedly singular
I tried the same instrument on V2.1.2 on Linux - no problem with
high-res, and I tried it with some older (1.3.2) version on Windows - no
problem either.
Best regards, Ivan
