If you have a Gretag Macbeth product registered with the company then you can obtain a useful utilitiy:
DisplayProfile freeware for Windows
DisplayProfile allows you to store multiple monitor profiles for your PC and have a way to easily switch between them. By moving the window to any connected monitor you can dynamically update the profile for that monitor. You can download the software here: http://gretagmacbeth.com/getfile?send=1&id=8712 (requires login)
This is a useful utility to have whilst we wait for Gretag Macbeth to release a calibration loader that works fully with Vista, possibly in the next release of i1Match. I will inform you here just as soon as I know….
