Macbook question - calibrating 2nd monitor

On a Macbook, if you profile the onboard screen, then plug in an external monitor and calibrate/profile that, does the Mac recognise which monitor you are using as the main monitor and switch profiles as necessary?

So when you're at home, your external monitor would be your main one with accurate colour, and the colours of the onboard screen would be unreliable; but as soon as you unplug the external monitor, the system switches to the onboard screen's profile - is that right?

(Sorry for the dopey question, I've never used a macbook).

I found that when i plug my Macbook pro into my television * Samsung 34" * that the colours are off and that the quality of my mac book screen goes down.

I don't know if anybody else faces the same problems.

Yes, that would be right, your macbook would attempt to use a suitable profile for your Samsung (without much success). That profile would clearly be unsuitable for your onboard display, so those colours would look wacky too.

Actually, that raises another question which I forgot to ask - does a macbook (or an MBP) have capacity for dual monitor profiles? At the same time, I mean...

Haha dude to be honest i have no idea. I'm just in love with it. I know that mine can support the cinema display screen but I'm not to sure about it being able to support both the cinema and mac book screen at the same time.

Are you happy with it?

Oh no, I don't own one. I just get asked to calibrate them periodically.

My experience is that is does support dual monitor profiles concurrently; sometimes I'll have both the onboard display and external monitor up at the same time, checking on system preferences/display brings up the profile used on each display and they are both different.

Thanks, Shepherd. Can I get somebody to second that motion?

C'mon folks - all I need is somebody to day "yes, Damien, I can confirm that a Macbook can support multiple monitor profiles, and automatically apply them as necessary" ...

Does this help you any?

Hubby has a question, and I did a search, and this thread looks like a good place to ask it.

For any Mac users, which monitor calibration tool do you use, and why?

He has 30 years of color correcting experiance in photo / electronics and just used the calibration tool in 10.55 on two Macbook Pro's, and they do not match.

Looking for hardware tool like the Spyder3 pro
