I was wondering if anyone has run into the following...

I'm trying to create a quick matrix profile using dispcal. The arguments I'm using look like this:

dispcal -v -d1 -c1 -o -yl -b108.41 -w 0.3132,0.3297 -G2.13 -F -XHP_calibration_2.ccss HP_Quick_Shaper

What happens when I load the profile is very strange... Not only is the profile on the screen I changed it for wrong but it also somehow corrupts the video LUT for my 2nd monitor. My 2nd monitor is an NEC2690 which I've calibrated and profiled with Spectraview II. I have a white background loaded up. When I load the profile for my main screen TO my main screen (in other words, I'm not loading the wrong profile on the wrong screen)... white turns to purple on the NEC??? I'm thinking that this has GOT to be an OS bug BUT, this dispcal, Argyll generated profile is the only profile that causes this behavior. If I remove the chromaticicity coordinates the problem goes away. What's even more strange... check out the values in the white point tag...

XYZ: 0.0095261, 0.01, 0.0104852
Lab: 8.9914424, -0.4370016, -3.5829517
LCH: 8.9914424, 3.6095032, 263.0461556
Yxy: 0.010, 0.3174159, 0.3332079
Luv: 8.9914424, 0.1995177, 0.4712492
6300K

Something must have gone very wrong there for the Y value to be 0.010.

Anyone seen this before? I had 1.3.4 on there and then I just downloaded the most recent Mac build and tried it again with the same results. OS version is OS X 10.6.8 on a 3,1 Mac Pro. I just can't figure this one out.

Thanks Francois,

Yes I posted to the Argyll mailing list. I figured I'd check here as well as I know there's a few Argyll fans.

Cheers, Joe
