If the madVR output levels are set to ‘TV levels (16-235)’:
In CalMAN, for ‘Input Signal Levels,’ select ‘Video (16-235).’
If the madVR output levels are set to ‘PC levels (0-255)’:
In CalMAN, for ‘Input Signal Levels,’ select ‘PC (0-255).’
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.
CAUTION: While CalMAN is running, it disables any existing 3D LUT in madVR, by default.
If there is already a 3D LUT loaded in madVR and you wish to first measure the performance of
the display with that 3D LUT, you need to enable the LUT during your display Pre-
Characterization steps.
To enable an existing madVR LUT:
On the CalMAN Source Settings tab, check the box for “Enable 3D LUT.”
(The button on the madVR Test Pattern Generator screen will not be active.)
The text at the top of the Test Pattern Generator screen indicates the status of any installed
madVR 3D LUT.
On the Performance Analysis page, the display measurements from the Gamma & ColorChecker page
are evaluated in a series of pass/fail performance parameters.
If the display fails any of the parameters on the Performance Analysis page, you should consider
using the following Display Optimization section of the workflow to optimize control adjustments on
the display itself.
If the display passes all of the parameters on the Performance Analysis page, you can skip the
Display Optimization section and go immediately to the Display Calibration section of the workflow.
