(Windows 98SE, Matrox G400 Max Dual). Graphics cards do not hold ICC profiles, but channel curves. Getting seperate channel curves to both monitors is possible with some cards, and not with others. Getting seperate profiles created, assigned, and used by Photoshop and other applications to correct the color differentially to parts of the application's display would be a significant trick. Windows does not automatically flash the associated channel curves to the card as profiles are selected in the OS as happens on the Mac. Due to the fact that color adjustments are happening at two different levels (vidoe card LUTs, and ICC profiles) it is difficult to be sure that you are in fact getting the whole process correctly for a given monitor in a multiple monitor configuration; yes the color is being changed, but is it by the LUTs only, or the profile only, or both; and is it the correct version of each? I stand by my statement that it is not currently practical to use two monitors and expect accurate color on each in Photoshop, unless they share a primary color definition, hence can use the same profile definition.
