Profiling Apple Cinema Display and Laptop?

[LeonD]

I have an Apple MacBook (glossy screen) and a 20" Cinema Display monitor (matt screen).  I'm trying to profile them using Pantone Color Vision's Spyder with PhotoCal.  I'm setting the defaults the same for both monitors.

My problem is that identical images look different on the two monitors.  One looks cooler than the other.  Could this be because one has a glossy screen and the other is matt?  Or should they be able to be configured to look the same?

Thanks,

I have the identical units although the 20" is running off of my tower. Both are calibrated with X-rite/Monaco EZ Color.

I'm unclear what you mean by "setting the defaults the same"? I would expect that the Displays preference dialogue box would let you run your MacBook from one profile and your second 20" monitor from a different one — which you would find on a second Displays Color panel. It works this way for me at work when I run a projector from an iMac on OS 10.4...  there are two separate Color panels within Displays preferences, one running each output display.

There will always be a contrast and saturation difference between the stand alone matt  LCD screen and glossy onboard screen. Colour should be very close though if they are independently running from separate calibrated profiles. If they are both running from the same profile, by definition, one of them will be running on a calibrated profile that wasn't created for it.

Hope this helps.

I also have a MBP 17 with the higher res glossy screen. I currently have Dell 2007FP 20" monitor which is not a bad monitor - a NEC 2690 is on its way. You images will look different regardless. You will have to target for the ACD and take how it looks on the laptop. It's just the difference in characteristics in the two monitors. One's an 8-bit monitor and the laptop is a 6-bit monitor. They were both engineered for different uses. It took me a while to get over this too.

Thanks for the replies.

When I said I configured them the same, it was the color temp and white balance.  The profiles are unique for each.

I contacted ColorVision and they said that the two montors would not look the same.  I'd think if you profile a monitor for a standard, then all monitors would look the same with that standard.

I'll need to compare my external monitor to my printers' output and make sure they look the same.  If thats the best I can do.

Thanks again for the help,

Are the measured brightness values the same?  If one is brighter than the other, it may appear warmer/cooler to your eyes when placed side by side.

Which color vision spyder is it?  I used to have the original and if I recall, it did not really measure brightness.  An upgrade to an EyeOne helped immensely.

It's the older Spyder using PhotoCal 2.7.6.

I'll have to check the brightness values.
