Preparing to Calibrate
In order to calibrate, the Z27x internal processor must be enabled. To meet the energy savings
requirements of Energy Star 6.0, the internal processor is disabled at the factory.
To enable the Z27x internal processor:
1. Press one of the five front bezel buttons to display the button labels and then press the bottom
Open Menu button to open the OSD.
2. In the OSD, select Management > Manage Internal Processor.
3. Choose Enable then press Select to turn the processor on.
4. Press Exit to exit the OSD.
Once enabled, wait approximately one minute for the processor to fully boot before beginning
calibration.
CAUTION: It is strongly recommended that calibration be performed in a darkened room. Stray light
bouncing off the monitor will negatively impact calibration accuracy.
