Dear Michael,
I regret that I missed the first parts of the thread. I spent a great
deal of time researching and making this work for myself a couple of
years ago ( I am now Mac based). At that point, none of the mid-range
dual head (nVidia / matrox) cards would support dual profiles,
despite claims by the sales people to the contrary. To their credit
PNY eventually provided me with a complimentary PCI card when the
Quadro card did not perform as claimed (ie support dual profiles)
The system worked and calibrated reliably with an i1 Pro and Match
under W2K / XP using the two separate cards.
Regards,
Nick.

Dual monitor calibration and profiling in Windows was discussed a
few weeks
back but I don't think a conclusion was ever reached.
As I recall, the consensus was that two profiles could be stored if
each
head of a dual head video card appeared as two separate devices in the
Windows device manager. But I think it was undetermined if two
calibrations
could be stored on a single card.
I checked with the manufacturer of my video card - 3D Labs -- and
here's
what they said:
"all our cards support an individual look-up table per each head."
So:
* if the card appears twice under "Display Adapters" in the
Windows
Device Manager, and
* if each instance has different Location info (e.g. PCI bus
1, device
0, function 0 and PCI bus 1, device 0, function 1), and
* if the manufacturer says that they support an individual
LUT per
head,
THEN does anyone know for certain if it is true that both monitors
can be
calibrated and profiled in a Windows environment? If not, where
would I
find an authoritative answer?
Thanks,
Michael
