Forgive a post that makes me look like a ColorEyes shareholder. I have no relationship with the company beyond being a customer, but I thought I'd post this excerpt from a press release, because there seems to be ongoing concern about apple displays. Also, according to the following, it sounds like coloreyes manages to make actual hardware changes before resorting to vid card adjustments. I'm happy to stand corrected if I'm not understanding this correctly:
"Integrated Color Corporation, creator of groundbreaking tools for digital cameras and monitor profiling, announced today that the company’s ColorEyes™ Display Pro monitor profiling software now supports the full range of Apple monitors, including the Apple Cinema Display as well as the MacBook, MacBook Pro and iMac.
ColorEyes Display Pro is one of the most powerful profiling tools on the market today and gives users unrivaled precision. The software works with most colorimeters and spectrophotometers on the market today, meaning users can simply upgrade their current software rather than purchasing additional hardware. And, with the addition of support for Apple monitors, ColorEyes Display Pro fits into virtually any workflow.
Apple has been very successful marketing high quality displays to imaging professionals. Customers demand accuracy from their displays and a simple process to get there. By adding hardware brightness control for Apple displays, ColorEyes Display makes short work of regular screen calibration."
That's all I've got, folks. Hope this helps.
