now I'm confused
DTEK, a UK ColorVision importer, told me that PhotoCal does not
include the "startup utility feature" to load an LUT to the card
but relies upon the SW [eg Photoshop's "display using monitor
compensation" facility to load the profile.
I was told that only OptiCal can actually load a CLUT to the
card. [In the same way that Prove it! does]

Thats how a monitor profile works: by loading curves to the video card...
Not to confuse calibration and profiling, I thought a monitor
profile worked when it was used by a program like Photoshop to
adjust/ compensate the monitor signal en route, isn't the loading
of an LUT to the card actually a calibration??
So we do this in 3 stages
Calibrate the hardware as well as we can using the monitor's controls
calibrate in software
profile
I realize that many monitor apps concatenate the last two steps.

so you have problems with NT too, but get on OK with
OPtiCal/Photocal and Win 2000, or Win 98?
