thanks, but I actually need to calibrate each display with an xrite i1display 2.

the software that drives the device, i1match, doesn't take the video card into consideration when establishing an icc profile. In fact, xrite recommends setting the video card settings, in the nvidia control panel, to their default values prior to calibration.

Needless to day, I'm able to calibrate my primary monitor but have not yet discovered a way to calibrate the second display. Assigning icc profiles can be done via the display settings dialogue box under color management, but I have to first create a profile for each device. Not sure how to do this for the second device.
