The Display Calibrator application is a simple assistant that walks you through the process of creating a profile for the displays connected to your computer.
The steps in the calibration process differ greatly depending on the type of display you're using and whether you're in “expert” mode. Adjustments roughly follow these steps: set up, native gamma, target gamma, target white point, admin, name, and conclusion. For most LCD displays, the calibration process skips several of the steps that aren't applicable.
