I've been in the tombs of color management hell for the better part of six months. Here is my story:
I have an old Mac G5 1.6Ghz tower with its original nVidia 5200 video card (bought used six months ago) connected to an HP 2335 monitor. I am using the latest OSX Tiger, Adobe CS2. When I look at my images, that once looked terrific on the screen, they look horrible--for lack of a better description, somewhat posterized in the denser color areas, oversaturated, pinkish in the highlights. My monitor is profiled, using the latest Eye One tool.
If I plug the HP 2335 directly into my Mac G4 12" Powerbook, and look at a file of an image, it looks fine. But if I view the same file through the G5 1.6 Ghz, I get the awful color.
I believe the monitor is properly calibrated. I thought that the video card might be acting up, but I replaced it with two identical cards, and both displayed the identical color issues. So I've ruled out the video card.
Can anyone out there in digital photo land suggest what to do, what is wrong? How could the computer itself adversely affect the colors I'm seeing? Is my computer dying? Any suggestions on what to replace it with? Would it make sense to try out an iMac 24" screen? As you can see, I am floundering around and have no idea what to think or do.
Any help would be appreciated.
