Contrast – There is no need to manually adjust the projector’s Contrast control, because, at the 0 preset
setting, the JVC projectors do not clip high luminance level signals.
Brightness – CalMAN provides a new “Brightness Value” control in the DDC Control Window that adjusts
the luminance levels of the darkest parts of images, without affecting other calibration adjustments.
Adjusting JVC projector black levels with this new Brightness Value DDC control in CalMAN (after the
gamma and CMS AutoCal calibrations) allows you to avoid adjusting the projector’s Brightness control,
which corrupts any calibration adjustments.
JVC Projector Display Calibration with CalMAN AutoCal:
The interaction between a JVC projector’s grayscale/gamma controls and its CMS controls is much more
pronounced than in most other displays.
Due to this pronounced control interaction, you need to perform CalMAN calibration on a JVC projector
in the following order, repeating the Grayscale/Gamma AutoCal:
1. Grayscale/Gamma AutoCal
2. CMS AutoCal
3. Grayscale/Gamma AutoCal
Note: The CMS1, CMS2, and CMS3 Color Management modes are global across all signal inputs and
picture modes.
Brightness Value
After the above AutoCal steps are complete, use the new CalMAN “Brightness Value” control to adjust
the luminance levels of the darkest parts of images for individual preference in different viewing
environments. This new ‘Brightness Value’ control is located on the Display Controls page in the
CalMAN DDC Controls dialog (click the Open DDC Window button on the CalMAN Display Control tab).
The Brightness Value control is very easy to adjust while viewing a multi-step Brightness test pattern
with steps at bit levels 16, 17, 18, 19, 20, etc. Or, adjust the control for proper black level while viewing
familiar video images with significant dark shadow content.
