On the Dolby remote, under System / Utilities / IP Configuration, note the monitor’s IP address.
Enter the Dolby monitor IP address, and then click Connect.
CalMAN then writes a unity 1D LUT file to the monitor. The monitor takes about a minute to load the
LUT data. Wait for the monitor to load the LUT before you continue the calibration.
2. Display Pre-Test section
In the Display Pre-Test section of the Color Cube workflow, you can measure the performance
of a display before you calibrate it, on the Gamma & ColorChecker page and on the Advanced
Linearity page.
Because t here are no Brightness, Contrast or Luminance controls available in the
Dolby Custom 1 and the Custom 2 operating modes, however, you will not optimize any
monitor picture controls before performing the 3D LUT calibration.
3. Display Optimization section
Because there are no Brightness, Contrast or Luminance controls available in the Dolby Custom 1 and
the Custom 2 operating modes, skip the Display Optimization section of the workflow. Skip directly to
Calibrate Cube LUT.
4. Display Calibration section
In the Display Calibration section of the Color Cube workflow, there are provisions for calibrating both a
1D RGB LUT (1D Ramp LUT page) and a 3D cube LUT (3D Cube LUT page). When we are calibrating a
Dolby monitor with a 3D LUT, we will skip the 1D Ramp LUT page (1D RGB LUT) and use only the 3D
Cube LUT page.
a. 1D Ramp LUT page
Skip over this page when creating a 3D LUT file for a Dolby monitor, since we do not need to
create a 1D LUT.
b. 3D Cube LUT page
1. On the 3D Cube LUT page, click the AutoCal (rotating arrows) button at the right end of
the meter action buttons. The AutoCal Setup dialog then appears (see below).
