Twin Apple 23" Calibration problems
on Oct 27, 2006 at 6:12:47 pm

Hi everyone,

We have just hooked up two Apple 23" Cinema HD displays (Alum) on our Quad G5 for our editing suite. The Quad is equiped with a nvidia 6600 graphics card. The problem is that we are unable to calibrate the two monitors to look identical. Using a dark grey backgrounfd for both, one of them always look "hotter" and kind of redish, compared to the other. This happened for the second time. The first time around we shipped back the "hotter" monitor to our internet dealer in Germany (we are based in Greece), which he was willing to exchange. The first time around that this problem occured, we found out on the internet that a whole batch of the 23" Apple monitors had a redish hue which could not be calibrated. This is the reason why we thought that the solution was to have our monitor exchanged for a new one. But as it seems, that must not be case, because: a) the problem is only apparent if the redish monitor is compared to another (the hue would be hardly noticable if the monitor is displaying on it's own, and most people that commented on the "batch problem" where using a single monitor) and b) the serial number of the "hot" display was not from the "hot" batch.

Has anyone encounterd similar problems? Is there a fix?

Is there a "right" way or an online guide for calibrating a twin monitor setup ( appart from using X's System Preferences--> Displays-->Color ?

Please keep in mind that the problem could be solved if the dealer was home-based by trying the twin display setup on the same machine before buying, but as I said the dealer is in Germany and the monitors are already paid, so that would not be an option.

Finaly, could this be an nvidia 6600 problem? (I have tried to hook the monitors on the opossite dvi inputs but the problem persists in the same monitor).

many thanks in advance

Have you checked that they're the same generation monitors?
