Colour Issues with PowerBook/Formac Monitor

Custom Profiles are always a good idea. I calibrated my pbs screen with the monitor settings in the system adjustments (sorry if this is the wrong word, haven't had Os X in english for a long time) and my Eizo using the calibration Software that came with it. Unfortunately you won't be able to get both screens to look the same, since the Formac, depending on when you bought it, is of course much brighter and has more contrast than the smaler pb screen. So the best thing you can achieve is having approximately the same colors but brighter on the Formac and a little bit darker on the pb screen. Removing a little bit yellow on the pbs profile might do a lot.

But to me there is also a big advantage when using 2 screens that do not display colours exactly the same. When designing websites you will never know what kind of monitor the person who will be visiting them has. You can check if your design/photos look good on different screens no matter if they are a little brighter or darker or something.
