Introduction to Color Calibration

The Z27x includes an internal color calibration and color management engine and does not require
software to be installed on a host computer in order to be calibrated. The following section discusses
the fundamentals of user calibration on the Z27x. A detailed discussion of calibration is covered in the
HP DreamColor Z27x Advanced User Guide.

The Z27x has been pre-calibrated at the factory to accurately display six of the most-frequently used
industry standard color spaces. In addition, all color spaces presets can be recalibrated by the user.
The following table lists the out-of-the box calibrated color space presets and provides information on
their calibrated configuration.
