Section 3: Operation
Input Peak Detector
This is a fast method for defining individual input levels, and improving the accuracy of input levels set by the 
Auto Input Level function. Enabling the Peak Detector activates a special operating mode for detecting only 
pixels that are considered black or white; all other levels are displayed as a mid-level gray. When used with a 
16-step grayscale pattern in which the 2 black and white bands are known to be at opposite edges of the image, 
you can watch these isolated areas while adjusting individual black levels, and Input drives until both bands are 
just visible. Images from this source will display correct blacks and whites without crushing or washing out. 
Input Level Detector
The Input Level Detector check box enables specific thresholds for blacks and whites. Input levels that fall 
below a specified level value (see below) are displayed as black, and all others are displayed as white. To use:
1. Enable Input Level Detector and display a continuous grayscale.
2. Set Level Detector Threshold to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set Level Detector Threshold to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
Level Detector Threshold 
Input Level Value defines the value to be used by the Input Level Detector in recognizing blacks and whites. 
See Input Level Detector, above.
Aspect Ratio Overlay
Check this box to display an overlay pattern over the image. The overlay shows the boxes corresponding to the 
size and shape of different aspect ratios.
Te s t  Pattern Color Swap
This function swaps the green and red color when drawing the Grid test pattern, and may be helpful when 
adjusting convergence on the projector.
Freeze Image During Auto Setup 
If selected, this will hide temporary image artifacts that may appear during the auto setup procedure.
Advanced Diagnostics 
Allows for the setting of advanced controls which 
may cause image disruption, including the possible 
loss of the OSD menus. These disruptions are only 
temporary; pressing 
EXIT to exit the menu will restore 
the settings and allow normal operation.
Output Peak Detector 
This is an aid for setting up the input levels. It 
causes the data to be processed so that very bright and very dark signals display as fully ON or OFF, and 
everything in-between is set to mid-level gray. The Input levels should be adjusted so that bright and dark 
objects in the image are just visible.
Output Level Detector 
This is an aid for setting up the Input levels. It causes the data to be processed so that all levels below a 
specified value are set to black and all above (and including) it are set to white. 
						

							Section 3: Operation
Mirage WU-L User Manual3-45020-100774-01 Rev. 2 (4-2012)
Level Detector Threshold
Specifies the threshold to be used by the level detector.
Light Engine Test Pattern 
One of 3 light module test patterns may be displayed: black, white, or grey scale.
LED Strobe Adjust 
During power up the projector will automatically optimize LED strobe timing, the time between when a LED is 
told to turn on versus when it actually does turn on. If the strobe timing is not optimal, color banding may be seen 
on grey levels. Use this advanced option to correct color banding by adjusting the slider left or right as required.
Service
The Service menu is intended for use by accredited Christie service technicians only. It is passcode protected.
Option Card Settings
Allows adjustment of any settings specific to each option card that is currently installed in the projector. 
ArrayLOC Menu
Use this menu to set up your projector array color 
and brightness. 
By default ArrayLOC is enabled and configured 
to automatically display a moderately saturated 
gamut at the maximum brightness the array can 
support.
For an overview of projector and source color 
settings, see 3.5 How Color Settings Interact in a 
Mirage WU-L Array, on page 3-61.
For an annotated walkthrough for setting up 
ArrayLOC and fine tuning the setup, see 6.6.9 
Bright/COLORLOC Setup Walkthrough, on page 
6-12 in the troubleshooting section.
NOTE: While working in the ArrayLOC menus 
and submenus, ArrayLOC displays a warning 
popup on the affected projector if adjusted 
settings fall outside the range the system can 
adjust for. Warnings include:
• Minimum brightness not met (BCLOC disabled)
• Minimum brightness not met (Warning)
• Min Gamut not met (BCLOC disabled)
• Min Gamut not met (Warning)
Bright/ColorLOC Mode
Use this option to set the Bright/ColorLOC mode.
•In ALL modes (except OFF), the projector:
•  Sets the flag to execute the Array BCLOC algorithm.
•In Cool or Bright mode, the LM color adjustment options on the Manual RGB Adjustment menu are 
disabled. 
						

							3-46Mirage WU-L User Manual020-100774-01 Rev. 2 (4-2012)
Section 3: Operation
•Cool mode: LED control performed by BCLOC. Color Space Correction is also performed 
electronically to achieve the target color space.
•Bright mode: This is the recommended (default) mode. The Bright mode is the same as Cool, except 
multiple LEDs may operate at the same time. This mode should provide brighter performance, but it will 
also generate more heat in the system. 
•In OFF mode, the projector:
• Disables BCLOC. Color control is done manually through Manual RGB Adjustment and manual color 
settings. 
• Clears the flag to execute the Array BCLOC algorithm.
• Restores the LM color adjustment options on the Manual RGB Adjustment menu and the manual color 
adjustments. 
• Ignores setting changes sent by a projector with the master flag set (Synchronize to this Projector on 
page 3-46).
•In Fixed mode, the LED setting is derived from Manual RGB Adjustment; Color Space correction is 
performed electronically to achieve the Target Color Space.
Synchronize to this Projector
To broadcast the ArrayLOC settings to the projectors in your array, you must define a projector as the 
“master” by checking the option Main Menu > Configuration > ArrayLOC > Synchronize to This 
Projector.
The master projector has access to most settings under the Bright/ColorLOC Configuration and Array 
Color Target submenus. These settings are greyed out on the other projectors in the array to prevent 
conflicting information from being sent to the array.
You can change which projector is the master at any time, by checking the Synchronize to This Projector 
option on another projector. The previous master projector automatically releases the setting.
See ArrayLOC Status on page 3-52. See Bright/ColorLOC Configuration > Bright/ColorLOC Array 
Status to check projector information.
A projector with BrightColorLOC mode turned OFF ignores BCLOC changes from master projectors.
If at some point you are working with another projector within your array or group, and decide to make some 
setting changes, you may not be able to do so as some settings will be locked (grayed out) because their 
projectors may not be the current master. You can however select the new projector as the master (as described 
above), and make your required changes. The previous master projector will relinquish control.

Bright/ColorLOC Configuration
Use the Bright/ColorLOC Configuration 
menu to assess and work with the capabilities 
of the projectors in the group or array.
Minimum Brightness
Use this option to set the minimum 
brightness (as a percentage of the target 
brightness) that the array will target, and to 
set 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. Excluded projectors 
are flagged in the Bright/ColorLOC Array 
Status window with anM.
If the projector falls below the minimum, the 
projector operates at its current brightness 
and gamut. Changes will not be made.
Minimum Gamut
Use this option to set the minimum gamut (as a percentage of the target gamut) that the array will display, 
and to set the threshold for alerts from projectors that cannot achieve the specified minimum. Projectors that 
fall below the minimum are excluded from the calculations of the common gamut and common brightness. 
Excluded projectors are flagged in the capabilities window with a m.
If the projector is unable to maintain the minimum gamut, the projector operates at the current brightness and 
color gamut. LED drive level changes and electronic color correction is not done. 
NOTE: The failure point for maintaining minimum gamut is 
calculated as: 
For example, see the diagram at the right. 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. 
Projector Capability
Identifies the projector capability with respect to the array-
common 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.

Section 3: Operation
Enable Warning
Check this option to enable warnings when either the projector brightness capability or color capability falls 
below the specified warning threshold.
Warning Brightness Threshold
Set the Brightness Warning Threshold as a percentage of the brightness target. When the common 
brightness reaches the warning level, all projectors in the BCLOC group issue a warning message: “Projector 
fails to meet warning brightness threshold of xx%; capability xx%.”
Changing this option:
• Recalculates the internal brightness warning level.
• If warnings are enabled, checks the current common brightness capability against the brightness warning 
level.
Warning Gamut Threshold
Set the Wa r n i n g  G a m u t  T h re s h o l d as a percentage of the target gamut. When the common gamut falls 
below this level, all projectors in the BCLOC group issue a warning message: “Projector fails to meet 
warning gamut threshold of xx%; capability Rxx% Gxx% Bxx%”.
Changing this option: 
• Recalculates the Internal gamut warning level.
• If warnings are enabled, checks the current common gamut against the gamut warning level. 
Array Color Target
Use this menu on the master projector to set the 
color target for the projector array. The settings 
apply to the projectors belonging to the same 
Brightness/ColorLOC group, which are set to 
synchronize with the group. These settings are 
enabled on master projectors only. 
Choose Maximum to view the common color 
gamut values for the array.
NOTE: 1) The recommended procedure for 
setting the color target for a projector array 
follows the description of the menu items. 2) If 
you are setting up a single projector, create an 
array of one and make it the master to enable the 
color controls.
• Target Color Space

Section 3: Operation
• RGB Brightness Target
Use this option to adjust the RGB brightness target for the array. 
• RGB Brightness
Use this option to adjust the brightness of the projector array as a percentage of the target brightness. 
• Bright/Color Group
Identifies the BCLOC group to which the projector belongs. 
The BCLOC group identifies a subset of projectors in the array that are used in the Array BCLOC algorithm, 
and are included in the Array Capability data table. 
Projector Color Adjustment
Use this menu to make ArrayLOC projector-
specific color adjustments. These controls are 
used to fine-tune the matching performed by 
ArrayLOC after the targets have been set 
through the Target Color Space menu.
These adjustments compensate for the 
projection system as a whole, including loss 
of brightness or color shift due to lens, mirror, 
and screen. For example, the mirror might not 
reflect blue 100 percent, or the screen might 
absorb more blue. Measure the output at the 
screen with a color meter and use this option 
to adjust the blue until you get the array color 
target value at the screen. 
Adjustments are specific to the target color 
space. If the color space is changed for the 
array, projector adjustments can be copied 
from the old target color space and fine-tuned 
again.
See also Adjust Projected White and Primary 
Colors for the Array on page 3-56.
• Target Color Space
Use this option to change the color space. 
Changing this option applies the red/green/
blue x/y values associated with the selected option. It also updates the red/green/blue components of each
