I have a Matrox Millenium P750 multi-monitor graphics card and a
ColorVision monitor Spyder with PhotoCal. I am using 2 CRT's in
independent mode.

I tried to assign profiles generated with the Spyder (one for each
monitor) by going to Windows (2000 Pro) Display Properties, Settings,
Advanced, Color Management to specify a profile filename. This works
fine for the secondary display.

But, when I try it for the primary, and hit the Assign button, I get
an error message from "Microsoft Color Management System" stating, "An
error occurred while associating <profile.icm>. This is not a valid
color profile." The same .icm file works properly elsewhere.

The only thing I can find in Matrox software is a calibration 'by
eyeball' similar to Adobe Gamma, which of course does not use the
colorometer.

Please advise!

The Photocal user guide states on page 4: "Multiple monitors ar
NOT supported on windows systems but are supported on Macintosh
systems".
I use Optical and calibrate my 2 LCD monitors individually by
disabling the other monitor using the display properties in win
XP using an ATI Radeon 9500 Pro. You know the procedure, Display
properties/ settings. Disable 2, make 1 primary, calibrate,
assign color profile. Then enable 2, disable 1 and make 2
primary. Calibrate and assign profile. Finally reenable 1 and
select whichever you want as primary. I have not used win 2000
in a while but believe it works the same way as XP
I have also emailed Colorvision and they replied:
"The Windows operating system will not allow the separation of
two profiles
to be used at the same time on a dual head video card. We are
currently in
Alpha testing of multiple monitor support with 2 separate video
inputs.
Please continue to check our website for updates.

Thank you for contacting us about your inquiry. I hope that I
have assisted
you efficiently and to your satisfaction. Please feel free to
contact us
again for other questions or issues."

Thank you

Not a totally satisfactory answer but worth a try

Thanks so much for the help! The only way I can figure out to *disable*
a monitor, is to tell the Matrox PowerDesk utility that only one
monitor is in my configuration, and reboot. I don't know if I also need
to unplug the other monitor when the system is down or not. Is this
what you do?
