Hi, I seem to be having an issue with a dual monitor calibration.

I haven't seen this before but I have just noticed that there appears a difference ( to me at least :-) ) in the displays after calibration. The colours, I would guess the saturation, are different.

I have the latest osx & i1 display 2 program so am at a bit of a loss to why they appear different.

I have tried swapping of the main display in osx and looking at the images again in lightroom, in case I had done something odd.

Any ideas ? Is this likely to some bug somewhere ? I'm expecting some difference in the brightness of the 2 monitors, which are both cinema displays, just not the colours.

Thanks

Brightness is the key first ingredient when trying to get two displays to match. Are both your monitors actually putting out the same brightness? At the end of the profiling procedure, i1Match shows you the results of your calibration. Look under Luminance: Current and see how your two screens compare. You may need to boost the brightness of one display just a bit in order to meet the brightness of the other. And then reprofile again at the new level. Everything else, like saturation and color, is scaled to luminance so this is important.

do you need two video cards to calibrate 2 monitors properly? I simply switched which was my main monitor in the preferences, calibrated, then switched back. does this work?
