I am having an issue with monitor calibration and am looking for input.
Consider two systems, we'll call them System A and System C. Both are the
same model Mac Pro with Dual-Core Intel Xeon processor running OS 10.6.8.
System A has more RAM than System C, but that is the only difference. Both
systems have an Eizo CG210 monitor.
Calibration using ColorNavigator 6.0.0.42 on both systems using an Eye-One
Pro. Here are the relevant results using the ISO 12646 Profile Quality
validation color set:
System A: Max dE2000 3.54; Avg dE2000 0.79
System C: Max dE2000 20.01; Avg dE2000 11.18
I next switched the two monitors so that System A has System C's monitor,
and vice versa. Here are those results:
System A: Max dE2000 3.41; Avg dE2000 0.64
System C: Max dE2000 20.04; Avg dE2000 11.16
I was surprised by this. Clearly it is not the System C monitor that was
going bad since it produce a good calibration on System A, and the System A
monitor performed poorly on System C. There must be something wrong with
System C, correct?
Any ideas what it could be? My first thought is the video card. Does that
sound likely? How would I go about figuring this out? What are the other
possible sources for this problem? I admit that this is a new one for me…
Thanks for any help you can provide!
