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:
n if
the card appears twice under “Display Adapters” in the Windows
Device Manager, and
n 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
n 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,
