3. Display Optimization section
In the Display Optimization section of the Color Cube workflow, you are guided to optimize any controls
the display may have for picture mode, color gamut, color temp, gamma, dynamic range, white point
balance, or white point luminance.
On the RGB Adjust page, if the display has RGB Gain controls, under the RGB Adjust Levels selection,
select “2 Point 30, 100%.” Click Read Continuous and adjust the display’s RGB Gain controls for RGB
balance at 100%. Accurate RGB balance at 100% is beneficial as foundation for 3D LUT calibration.
4. Display Calibration section
In the Display Calibration section of the Color Cube workflow, there are provisions for calibrating both a
1D LUT (on the 1D Ramp LUT page) and a 3D LUT (on the 3D Cube LUT page).
When we are using the CalMAN Cube Generator function to produce a 3D LUT file for madVR, we will
skip the 1D Ramp LUT page and use only the 3D Cube LUT page.
a. 1D Ramp LUT page
Skip over the 1D Ramp LUT page when using the CalMAN Cube Generator function to produce a
calibration LUT file for madVR.
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).
CAUTION: Before you make any adjustments to optimize the display controls or perform 3D
LUT calibration, be sure to disable any existing madVR LUT.
Failure to disable an existing madVR LUT before making any adjustments or creating a new
LUT will result in an inaccurate display calibration.
To disable an existing madVR LUT:
On the CalMAN Source Settings tab, uncheck the box for “Enable 3D LUT.”
The text at the top of the Test Pattern Generator screen indicates the status of any installed
madVR 3D LUT.
