Synchronize Keys, Test Pattern, Color Enable
Use the Synchronized option to set the projector to listen for remote keystrokes through the ArrayLOC 
network and the master projector. All synchronized projectors respond to the same keystrokes. Double key 
strokes may not register correctly, use alternate key commands instead.
A synchronized projector automatically starts listening to its IR receiver if the master projector becomes 
unavailable, for example if it goes into standby mode.
You can override the key synchronization by using the Proj key and projector address to communicate with 
a specific projector, or you can use a wired remote with a specific projector.
Independent indicates that the projector listens to its own IR remote receiver. It is the default option. 
Change this setting for each projector individually. 
NOTE: ArrayLOC network communication overrides RS-232 serial communication for keys.
Synchronize Frame Delay
Use the Synchronized option to synch the frame delay on all the synched projectors in the ArrayLOC 
group. Set the delay value in Set Array Frame Delay. 
NOTE:To use this synchronization feature, set 
FrameLocking to FrameLOCK. See Frame Locking on page 3-29.
Independent is the default option. Change this setting for each projector individually. 
Set Array Frame Delay
This option indicates the current frame delay for all the synched projectors in the ArrayLOC group. Use 
this control on the master projector to adjust the frame delay for the synched projectors in the ArrayLOC 
group. Set the value equal to or higher than the reported Minimum Array Frame Delay value. Setting the 
value lower than the reported minimum may result in tearing artifacts. 
						

							Section 3: Operation
Mirage WU-L User Manual3-55020-100774-01 Rev. 2 (4-2012)
Minimum Array Frame Delay
Indicates the largest minimum frame delay reported for the ArrayLOC group. The value is the largest of 
the reported minimum frame delay required to render the display without tearing artifacts on each 
projector in the ArrayLOC group.
Synchronize RGB Brightness
Use the Synchronized option to synch the RGB brightness for all the synched projectors in the ArrayLOC 
group.
Change this setting for each projector individually. Synchronized is the default option.
RGB Brightness Target
Use this option to adjust the target brightness for all projectors in this array.
RGB Brightness
Use this option to adjust the brightness of the projector array as a percentage of the target brightness. 
Managing Colors with ArrayLOC
Mirage WU-L projectors use ArrayLOC to display a reasonably saturated gamut at the maximum brightness 
that all the projectors in the array can support. ArrayLOC monitors the projector array and adjusts settings 
automatically.
To manage color using ArrayLOC:
•Take Control of the Array on page 3-55
•Adjust Projected White and Primary Colors for the Array on page 3-56
•Fine-tune Whites, White Brightness, or Primary Colors on page 3-57
•Fine-tune Projector Colors With a Color Meter on page 3-58
NOTE: ArrayLOC is enabled by default. 
Take Control of the Array
To make color adjustments across the array, you must 
make the projector you are working with the master 
projector.
1. On the projector you want to work with, access 
the ArrayLOC menu: Main Menu > 
Configuration > ArrayLOC.
2. Check Synchronize to This Projector. 
The current projector becomes the master 
projector. Changes you make in the Array Color 
Target or ArrayLOC Configuration menus on 
the master projector are broadcast to the other 
projectors in the array.

Section 3: Operation
Adjust Projected White and Primary Colors for the Array
User-defined target color spaces allow color primaries and white points to be adjusted independently. For 
example, you can select the target color space User 1, copy the values from the target color space Factory, 
leave the color primaries, and adjust only the white point. All the settings for a user-defined color space are 
editable.
1. Navigate to Main Menu > Configuration > ArrayLOC > Array Color Target. 
2. In Target Color Space, select one of the User settings to modify.
NOTE: To use another color space as a starting point, select a source color space from the Copy Color 
Space From list. When using Maximum as a starting point, the values reflect a color space larger than 
capable for the best array color saturation. The values may not reflect real-world colors.
3. Check both Auto Color Enable and Test Pattern Enable, the system (background) color changes to the 
target color being adjusted (for example, Target Red x invokes a red background). All other menu options 
change the system color to white as long as Test Pattern Enable is checked.
4. Adjust the color primaries (for example, Target Red x and Target Red y) for the color space. 
5. To adjust white in the image, select a User White item (1 to 4).
• Adjust Target White x and Target White y values, or
• Check the Set White to Color Temperature box and set the White Color Temperature value to any 
value between 3200 and 9300°K.
6. To adjust the target brightness for the array, adjust RGB Brightness Target on the master projector. For 
maximum brightness, set the value to a large number, such as 1000. 
7. If the array appears matched across all projectors for color and brightness, color setup is complete, 
otherwise see Fine-tune Whites, White Brightness, or Primary Colors on page 3-57.
NOTE: Array Capability expresses the common gamut red, green, blue and white values of the current 
projector as a percentage of the array target color and brightness values (see Minimum Gamut, on page 3-
47). If any of these values is less than 100, there is at least one projector in the array that cannot achieve 
target values. Reducing Target Color Space and RGB Brightness Target values in the master projector will 
bring the Array Capability values closer to 100.

Fine-tune Whites, White Brightness, or Primary 
Colors
 
Projector Color Adjustment lets you fine-tune color 
or brightness for individual projectors that don’t quite 
match the array. For more information, see  Projector 
Color Adjustment, on page 3-41.
These steps outline color adjustments using projector 
color settings until the colors appear to match the rest of 
the projectors in the array. Color adjustments are 
evaluated by eye. A color meter can help determine the 
change required, but the results are still evaluated by 
eye. For information about using the color meter with 
this procedure, see Fine-tune Projector Colors With a 
Color Meter on page 3-58.
1. Navigate to Main Menu > Configuration > 
ArrayLOC > Projector Color Adjustment.
2. Projector Color Adjustment settings are specific to 
each color space. To use existing fine-tuning 
adjustments as a starting point, select a tuned color 
space from Copy Adjustments From. 
3. Check both Auto Color Enable and Test Pattern 
Enable, the system (background) color changes to the target color being adjusted (for example, Target Red 
x invokes a red background). All other menu options change the system color to white as long as Test 
Pattern Enable is checked.
4. Navigate to Main Menu > Configuration > Communication. Note the IDs of the projectors you want to 
fine-tune.
5. To adjust white color and brightness settings (repeat for each projector that needs adjustment):
a. Press P
ROJ,  on the remote. The remote directs commands to the specified projector 
only.
b. Use the White Brightness Adjustment to roughly match the white brightness of the array. A higher 
value makes the projector image brighter.
c. Adjust the Red Part of White, Green Part of White, and Blue Part of White to match the white 
color to other projectors in the array.
d. Readjust the White Brightness Adjustment control if matching white colors revealed mismatched 
white brightness.
6. Navigate to Main Menu > Configuration > Communication. Note the IDs of the projectors you want to 
fine-tune.

Section 3: Operation
7. To adjust color primary settings (repeat for each projector that needs adjusting):
a. Press P
ROJ,  on the remote. The remote directs commands to the specified projector.
b. Adjust the XXX Part of YYY controls where and YYY is the color being adjusted, and XXX and 
YYY are not the same color (ie. non-dominant colors). Negative values for the non-dominant colors 
are permitted. Adjusting XXX Part of XXX adjusts the color’s brightness and affects the color of 
white. 
Example: If the blue primary color does not match. Use the Red Part of Blue and Green Part of Blue 
controls. Negative values will increase the saturation of the blue. Values between -15 and +3 work 
well.
NOTE: For information about using a color meter with this procedure, see Fine-tune Projector Colors 
With a Color Meter on page 3-58.
8. Repeat steps 6 and 7 until all the primary colors are matched.
9. After adjusting the primary colors, verify that the white color and brightness still match. Repeat the process 
if necessary.
Fine-tune Projector Colors With a Color Meter
To use a color meter for projector color adjustments, follow the instructions in Fine-tune Whites, White 
Brightness, or Primary Colors on page 3-57, but use a color meter for the XXX Part of YYY adjustments.
1. To note the xy color values reported for the common gamut, navigate to Main Menu > Configuration > 
ArrayLOC > ArrayLOC Status. For example, see Figure 3-19.
2. Measure the projected primary color with the meter and compare the metered values to the common gamut 
values.
3. Use the adjustment guide to determine how to adjust the Projector Color Adjustment values to correct the 
differences.
 The adjustment guides are color coded. The suggested corrections are also color coded, and 
reflect the direction of the change, + or -. For example, if the measured red is 660, 325 and the Common 
Gamut value is 640, 330 then the measured x is high (High X) while the measured y is low (Low Y). The 
corresponding quadrant of the RED guide indicates +G (increase green) to correct the mismatch with other 
projectors.
 
 Figure 3-22 Red, Green, Blue, and White Color Adjustment Guides
1Some corrections require both red and green adjustments. 
2Alternative: decrease blue (-B) instead of increasing red and green. 
3Alternative: increase blue (+B) and increase green (+G) instead of decreasing red, and increasing green.

Secondary Video Options
The controls adjust the secondary image in the same fashion as the main image controls, see Video Options 
Menu on page 3-20. 
Secondary Input Levels
The controls adjust the secondary image in the same fashion as the main image controls, see Input Levels 
Menu on page 3-22. 
Secondary Advanced Image Settings
The controls adjust the secondary image in the same fashion as the main image controls, see Advanced Image 
Settings Menu on page 3-25.
Fade Time
Controls the amount of time (in seconds) it takes to fade between images on a source switch. It also fades in the 
secondary image and OSD if possible.
Frame Locking
Enable or disable Frame Lock. When set to Frame Lock, output image frames are locked to the input if 
possible. When Locked, the output is always locked to the primary input. When set to Free Run, sets the 
output to the Free Run Frequency value. The projector will not display 3D content when it is set to Free Run. 
Auto Input Searching 
When enabled, the system will continually search for the next valid signal when no signal is present or when 
loss of sync occurs on the current user-selected input. In the case of multiple signals to choose from, the order 
is based on slot, followed by inputs on that slot.
HDMI Output Loop Source
This control is used to configure the HDMI output options. Selecting Direct Loop will directly pass-through 
the HDMI Input signals: on the same Twin HDMI Input Card, the Input1 signal is looped to Output1 and the 
Input2 signal is looped to Output2. Selecting Main/Secondary Loop will loop the main and secondary video 
to the outputs, regardless from which card these signals originate. The Main video signal is looped to Output1, 
and the secondary video signal is looped to Output2. Selecting Disable will shut OFF the HDMI outputs 
completely.

3.5 How Color Settings Interact in a Mirage WU-L Array
Image Settings > Color Space tells the projector how to interpret video data coming in. See Color Space on 
page 3-20. 
Image Settings > Advanced Image Settings > Color Settings adjusts the color temperature. Use ArrayLOC 
color and color temperature settings instead. When enabled, ArrayLOC overrides the settings on the Color 
Settings menu. See Color Settings on page 3-27.
Configuration > Geometry & Color > Manual RGB Adjustment is the manual way to set the levels of each 
LED. These adjustments are available when ArrayLOC is OFF or set to Fixed mode. When ArrayLOC is set to 
Cool or Bright mode, LED levels are controlled by ArrayLOC function automatically.
Configuration > ArrayLOC > Array Color Target tells the projector what you expect to see on the screen. 
This is the recommended way to control the color space for the projector and array. See Array Color Target on 
page 3-41. This menu is also available under Configuration > Geometry & Color.
Configuration > ArrayLOC > Projector Color Adjustment lets you adjust each projector output so that it 
represents the color target. Adjustments compensate for projector-to-projector differences and 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. You can measure 
the output at the screen with a color meter and use this option to increase the blue until you get the array color 
target value at the screen. See Projector Color Adjustment on page 3-50. This menu is also available under 
Configuration > Geometry & Color.
Configuration > ArrayLOC > Projector Color Adjustment > White Brightness Adjustment lets you turn 
the brightness target adjustment into a meaningful number, for example a number that relates to Ft-L. See 
6.6.10 Array Status Decoder & Setting the RGB Brightness Target Unit in the troubleshooting section.
3.6 3D
The Mirage WU-L projector is capable of displaying stereoscopic 3D video sources. The Mirage WU-L relies 
on additional hardware, such as stereo emitters and glasses, to complete the display system. 
Images generated from a stereo 3D-video source consist of a series of images (frames) that alternate quickly 
between two slightly different view points, corresponding to our left and right eyes. When these frames are 
displayed fast enough and viewed with special stereo glasses synchronized to the left/right (L/R) changes, the 
resulting image appears with the same depth and perspective that is sensed in the real world. 
NOTE: The type of special glasses can be active stereo or passive stereo glasses depending on the type of 
stereo controllers and screen used.
3.6.1 Requirements
Stereo 3D applications require a stereo 3D-capable source, special hardware/software setups described below, 
and the projector’s 3D Settings menu option to control the projector’s processing, synchronizing and 
displaying of your stereoscopic 3D source material.
Hardware
• Christie Mirage WU-L projector.
• Christie GPIO 3D Stereo Sync Cable (required for Mirage UI-L projectors; ensures minimum frame delay). 
This GPIO cable is standard with all Mirage WU-L projectors.  
						

							3-62Mirage WU-L User Manual020-100774-01 Rev. 2 (4-2012)
Section 3: Operation
• A source, usually a computer with a stereo 3D graphics card capable of displaying progressive scan 
(alternating frames) of OpenGL quad buffered stereo 3D applications. Suggested video cards include ATI or 
NVIDIA. 
• Emitter for controlling active shutter glasses.
• An appropriate qualified device that mounts in front of the lens of the projector that will process the light 
from the lens into a passive polarized light. Contact your Immersive dealer for more information.
Software or content
• Any 3D computer software that supports active or sequential 3D stereo on a supported computer/graphic 
card.
• A video stream from video source that has been prepared to be sequential content. The Mirage WU-L also 
supports stereo signals prepared on either a compatible Dual or Single link HDSDI format. 
NOTE: The VGA 
port does not support 3D.
• Frame locked Passive sources are also compatible with the Mirage WU-L with the appropriate primary and 
secondary input card.
3.6.2 Connecting the GPIO 3D Stereo sync cable
This GPIO cable provides the means for synchronizing the various components in your 3D system. Your 
source, projector display output, and emitters or 3D passive filter system can then operate together with 
precision to minimize cross-talk and color artifacts. Connect as shown below in Figure 3-23.
NOTE: For Mirage WU-L, inputs A and B are not required, but recommended to ensure that stereo is 
configured correctly, especially for multiple projector setups.
 Figure 3-23  Mirage GPIO 3D Stereo Sync Cable
Connecting Two Stereo 3D Sync Inputs (Recommended for multiple sources)
Connect your video card’s stereo 3D sync cable to either Input A or either Input B on the GPIO 3D Stereo Sync 
Cable. These inputs are provided to allow you to connect two different Stereo 3D sources and conveniently 
switch the display back-and-forth between them.
