I recently got a 23 inch apple cinema display. After hooking it up and seeing the drastic difference between the new screen and my macbook pro screen, I decided it was time to learn how to calibrate. I purchased a spyder2express from amazon and have been fooling around with it. I finally figured out how to get a color profile for each monitor without it setting that calibration for the other monitor as well. But now that I am sure that I have each monitor calibrated with its profile, the monitors differ slightly. They are much better than they were before, but my cinema display still appears to be warmer than the macbook display. This is most noticeable to me in the yellow and orange range.

Does anyone have any advice? I had thought that when i was calibrated, what you see would be what you get, but now that I am "calibrated", I am not sure which monitor is more accurate.

Thanks!

You're unlikely to get an exact match between a laptop screen and a standalone LCD monitor. Different backlights, manufacturing specs, graphics cards and LCD technology will produce different color and brightness results. The best you can do is get close IMO.

I have two monitors connected to my desktop and even though calibrated they do show differences.

1 has a contrast ratio of 500:1 and the other is 1000:1. The 1000:1 image looks better but the print generally turns out like the image on the 500:1 monitor.

Both have independent colour sliders which were used during hardware calibration. The higher contrast monitor seems to have more saturated reds/oranges than the other one.

Has your large monitor got independent colour sliders (accessed by a menu on the monitor), did you use them in setting the profile? If so you will always get a better calibration than with software adjustment alone (which I dare say how the laptop was configured). If you just used software for both of them then it all comes down to how you have the large screen set for white balance - I have two quite different monitors on my system (the large one a Dell widescreen thing and the secondary a smaller 19" Samsung TFT 4:3 AR screen). I used the monitor colour adjustments on both screens and I have a very close match between the two - I only really notice a difference in white balance, the Dell is everso slightly warmer than the other one on pure whites or light grays - but other colours are spot on.

Thanks for the help everyone. I do not have any independent color sliders, so that doesn't seem to be an option.
[user]cpanaloti[/user], i believe the contrast ratio of the cinema display is 700:1, while the laptop is 400:1, so I am seeing differences similar to what you described. I don't know if this is related.

It will make a difference. The higher the ratio the brighter the image - although a lot of it is marketing talk - there is a difference.

I have two different brands of LCD's and use a Huey Pro to claibrate them (Vista system). One is a 24" Viewsonic 1080p running at 1920x1080 and the other is a Dell 20" running at 1680x1050. The Huey Pro handles both when hooked to the same video card just fine with very little difference once calibrated. As mentioned the Dell seems a slight bit warmer.
