TIP: To determine if the processor is disabled, look at the Main menu in the OSD. If the Calibration menu is
unavailable, the processor is disabled.
To enable the internal processor:
1. Press one of the front bezel buttons to display the button labels, and then press the Open Menu button
to open the OSD.
2. Select Management, and then select Internal processor.
3. Select Enable calibration to turn the processor on.
4. Press the Exit button to close the OSD.
Wait approximately one minute for the processor to fully boot before attempting a calibration.
Enabling calibration and external instruments
By default, calibration is enabled and both internal and external instruments are allowed. This can be
changed from the Management menu. If you enabled the internal processor and cannot calibrate, calibration
may be disabled on your display.
To enable or disable calibration:
1. Press one of the front bezel buttons to display the button labels, and then press the Open Menu button

2. Select Management, and then select Calibration Conguration.
3. Select Enable to toggle calibration on or o.
4. Press the Exit button to close the OSD.
In addition, you can control whether external instruments are allowed for calibration. See Using external
measurement instruments on page 66 for more information on external instruments.
To enable or disable the use of external instruments:
1. Press one of the front bezel buttons to display the button labels, and then press the Open Menu button
to open the OSD.
2. Select Management, and then select Calibration Conguration.

Calibration environment
The recommended calibration environment varies depending on the instrument you are using for calibration.
If you are using the built-in colorimeter or a direct-contact instrument, such as the Klein K10-A or an X-Rite
i1Display or i1Pro, HP recommends that you calibrate in dim lighting with no direct light hitting the screen. If
you are calibrating using a noncontact instrument, such as a Photo Research spectroradiometer, HP strongly
recommends that you calibrate in a completely darkened room or that you use a dark enclosed environment,
such as a calibration box.
To calibrate multiple displays, HP recommends that you identify a light-controlled area from which to perform
the calibrations. This area should allow for multiple displays to be staged and warmed up prior to calibration.
If using an instrument on a xed tripod, as is common for the Photo Research instruments, HP recommends
that you line up one display so that it is properly positioned relative to the instrument, and then mark the
table/bench position of the display or use a mounting jig. This allows you to position each display at the
proper measurement location.
