I wonder the same thing; I think you would be better off using the ColorNavigator software. The CG211 has a 12-bit internal LUT for calibration, it would be a shame not to use it (the i1Match software will use the video-cards 8-bit LUT, not the Eizo's hardware LUT).
The ColorNavigator software can be used with the i1 spectro, no need to use the i1Match software just because you want to use your spectro.
