Video Cards in Older MacBook Pro's

Do the older MacBook Pro's with the dual video cards (Nvidia 9400M & 9600M GT) have the capability to calibrate two monitors simultaneously? Meaning, can I load the LUT for the MBP's monitor to one and an external display to the other so that the profiles don't effect each other? I use a Spyder3Pro for calibration if that matters.

Yes. I have the Spyder pro too and I have three profiles. One for the main screen, one for a home monitor and one for a work screen.

Although that is the Spyder Pro software doing that, not the computer.

The color profiles are saved, so all you do is go into system prefs and assign the profile to the different displays.

So unlike my current aluminum unibody MacBook with a single video card, I can have both monitors running at the same time without having profiles interfere with each other? Right now when I am connected to my 23" NEC monitor I basically have to calibrate it once before I start working because the video card can only load one LUT at a time.

Does anyone know if the newer MBP's single video card can handle two at once?

Every Mac with a video out supports two monitors. The number of video card's inside your Mac does not effect how many screens you may use. You're limited by the hardware connections available - and in this case it is one. If there is a port, it should work. Otherwise, the 99% of PC laptops on the market with only one video card would not be able to have an external monitor/projector connected to them.

Apple allows you to calibrate each monitor independent of each other. When you went through the Spyder calibration steps, you should have performed it twice. One for the main screen and again for the second screen. The name you saved each as should have been different; such as Monitor 1 and Monitor 2. You should also allowed those profiles to be shared if you have multiple users on that machine. Even when you "Mirror" your screens, you should be able to calibrate each separately.

Perhaps you should post a screen capture of what you are seeing. Maybe something's being lost in the translation.
