Configure Bright/ColorLOC

This menu is used to configure the warning and minimum brightness and gamut thresholds.
1. From the Main menu, select ArrayLOC >
Bright/ColorLOC Configuration to access
and work with the capabilities of the projectors
in the array.
2. Set the Minimum Brightness value (as a
percentage of the target brightness). This
setting indicates the minimum brightness that
the array will target, and the threshold for
alerts from projectors that cannot achieve the minimum.
Projectors that fall below the minimum are excluded from the calculations of the common
gamut and common brightness. If the projector falls below the minimum, the projector
operates at its current brightness and gamut. LED drive level changes and electronic color
correction is not done.
3. Set the Minimum Gamut value (as a percentage of the target gamut). This setting indicates the
minimum gamut that the array will display, and the threshold for alerts from projectors that
cannot achieve the specified minimum.
Projector Capability identifies
color gamut as defined by Color Target and Brightness Target. 100 % indicates the
projector meets the target. A greater number indicates that the projector can exceed the
target. A smaller number indicates how much the projector falls short of meeting the target.
The failure point for maintaining minimum gamut is calculated as:
For example: Where b is the length of the line from the
target white point to the target color primary, and a is the
length of the line from the target white point to the
intersection of the projector capability gamut line and the line
from the target white point to the target color primary.
4. Set the Warning Brightness Threshold as a percentage of
the brightness target. Making changes to this option,
recalculates the internal brightness warning level, and if
warnings are enabled checks the current common brightness
capability against the brightness warning level. When the
common brightness reaches the warning level, all projectors
in the BCLOC group issue the warning message, Projector
fails to meet warning brightness threshold of xx%;
capability xx%.
5. Set the Warning Gamut Threshold as a percentage of the target gamut. Making changes to
this option, recalculates the internal gamut warning level, and if warnings are enabled,
checks the current common gamut against the gamut warning level. When the common gamut
falls below this level, all projectors in the BCLOC group issue the warning message, Projector
fails to meet warning gamut threshold of xx%; capability Rxx% Gxx% Bxx%.
