Hi everbody, I'm using a MacBook Pro Unibody and the Aurora Blue wallpaper for my desktop (the blue version of the standard wallpaper, comes with the server edition of Mac OSX, I think). When I switch between the two graphic cards (resp. the graphic chip and the card), I notice that the blue looks correctly when using the 9400, but definitely too purple when switching to the 9600. When I plug in my external ACD, both cards show the same correct blue. Is this normal? It's not that big of a deal and I'm not able to calibrate a display, but I'm just curious if this is normal ... Thanks in advance!!
