I've been all over the internet looking for the solution to this. Maybe someone here knows the answer. Hope this isn't too O/T.

I have a dual 2.0 G5 that came with an nvidia GeForce FX 5200. I'm using two of those early Apple Studio Displays.

The configuration was easy, but one thing I can't figure out is that when I do the calibration in System Preferences, it only affects one of the displays (the one with the dock.) This is pretty important to me, as I keep my displays pretty dark, otherwise my eyes get tired more quickly.

(They're not in 'mirror' mode, BTW.)

OS is 10.3.9.

Thanks!

Two easy options I can think of:

1. Go into System Prefs/Displays/Arrangement, and move the dock to the other display, then calibrate it. After you're done, move the dock back to it's original position.

2. Unplug the first display, leaving only the second display. Then you can calibrate it, and plug the other one back in, and you should have both calibrated.

do you have a monitor icon in the finder bar on the far right hand side? if so.. if you click on it.. it will show you both monitors and you can take it from there....

hope it helps

On my similar set-up I get two windows under the "monitors conrol panel". The primamry monitor has "display, arrangement and color" options, and the other has "display and color" options. I calibrated one of the monitors and then set the other monitor to the calibration setting I just created.

Taking it to the next level, I used one of those Spyder hardware calibration things. It made a big difference, but that's probably overkill unless you're a designer or really picky about color.

Gah!

When I checked under System Preferences, I only got one control window. I didn't think to look there because I was sure it was another way to get to the same place.

Thanks!

no problem.. have fun...
