•Show Blending Overlap turns your defined blend width area to solid grey so that, if needed, simply 
overlapping the grey bars can seamlessly align two adjacent images. Toggle the Show Blending Overlap off 
to reactivate the blend effect. 
NOTE: Blending Overlap appears as Reserved when Christie TWIST is 
installed.
Other Functions
For convenience, the Edge Blending submenu also includes related options for enabling a specific color and/
or test pattern, or for working with colors or the lamp. Such functions duplicate those provided elsewhere in 
the menu system.
Edge Blending Procedure
NOTES: 1) Before attempting to work with edge blending software functions, align the projectors/images by 
correctly overlapping the displays from your intended external source. 
2) Match colors and the brightness 
uniformity.
IMPORTANT! For a shared edge, all blend procedures and settings should be identical on both projectors.
1. Start with two projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in the top check box.
3.
SET STARTING POINTS FOR ADJUSTMENT
a. Set all blend widths to 0.
b. Go to More and set everything in the Edge Blending menu to 50.
4.
SET BLEND WIDTH On one projector, increase the Blend Width for an overlapping edge (for example, if 
the projector image is on left, its right edge overlaps the adjacent image—adjust Right Blend Width). Use 
the same setting on the second projector for this shared edge.
5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the overlapping blends 
disappears or just changes to very light grey. For the shared edge, use the same Blend Width setting on 
each projector. 
NOTE: If the best blend appears to be between two settings, select the wider setting for both 
projectors.
6.
CHECK BLEND If the blended region appears too dark or light in relation to the rest of the image:
a. Increase Blend Midpoint in both projectors to “lighten” the overall blend, decrease to “darken” the 
overall blend.
b. Adjust Blend Shape in both projectors to fine-tune change the amount of mid-grey intensity (as 
opposed to black/white) in the blend.
7. Repeat with remaining projectors / overlaps.
8. Check completed display wall with the desired external signal.
9. If necessary, adjust the mechanical alignment to maintain perfect pixel-on-pixel alignment over time.
In applications where you are projecting only white or light images, the Blend Width may be slightly higher—
set according to how much overlap you have between images. Use the following as a guide (examples show 
overlapping width only—values for overlapping height will differ). 
NOTE: Recommended overlap is 12.5% - 
25%.

Section 3: Operation
COLOR ADJUSTMENTS BY X/Y - Submenu
Enter known x/y coordinates from the chromaticity graph
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color 
performance or “gamut”. Sometimes known as Comprehen-
sive Color Adjustment™. 
2) Factory-defined primary color 
levels, which ensure a specific color performance from 
projector-to-projector, can be calibrated in the Service menu 
only. The factory settings can be recovered with selection of 
“Reset to Factory Defaults?” in the Color Primary Settings 
submenu accessed via the Service menu (password-
protected).
From the factory, the projector can utilize any of the three pre-defined color performance settings identified at 
right (default=Max Drives), or colors can be driven on the basis of color temperature. For most applications, 
one of these gamuts will produce accurate and realistic colors from a variety of sources. They can be applied at 
any time in the Advanced Image Settings menu (“Select Color Adjustment”), and are not adjustable.
DEFINING “USER” COLOR GAMUTS You may find the pre-defined “Select Color Adjustment” options 
do not suit your needs. For example, you may require a unique color gamut (range) for a single projector or 
application, or you may need to precisely match colors across multiple adjacent displays. In such cases, use the 
Color Adjustments by X,Y or Color Saturation submenu to define the precise hue of each primary color 
component (red, green, blue, and white) used to generate the millions of colors produced in displays. You can 
create up to four custom color gamuts (User 1, 2, 3, or 4) with these adjustments.
NOTE: The two menus differ only in their user interface, so use whichever menu best suits your needs and 
application. A color meter can help with adjustments.
 Use this submenu to create, alter or copy a color gamut (i.e., “color adjustment”). Controls in this menu define 
the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of 
colors produced in displays. The x/y coordinates for each color define its location on the standard CIE 
chromaticity graph, see Figure 3-38 CIE 1931 Chromaticity Diagram. Changing either or both of these 
numbers will change the hue of the color, and relocate the “triangle” for possible colors. For example, 
changing the x/y coordinates for red may move the color closer to orange or closer to violet, which will in turn 
affect all displayed colors having a red component. Adjust the slide bars or enter new specific coordinates as 
desired to define or change up to four “User” color gamuts needed for your environment and applications. 
Apply at any time in the Advanced Image Settings menu.

FIGURE 3-38 CIE 1931 CHROMATICITY DIAGRAM
NOTE: Keep new x,y coordinates within the original color gamut triangle shown here.
COLOR SATURATION - Submenu
Adjust color slide bars and judge image color by eye or meter. A user-defined color “adjustment” can be 
applied by selecting it in the Advanced Image Settings menu (select ‘Color Adjustment’).
Use this submenu if you do not have specific color coordinates in mind and will judge color performance by 
eye or meter. Like the Color Adjustment by X,Y submenu, each color control actually defines new x/y 
coordinates for that color and changes its hue.
NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates shown in the Color 
Adjustment by X,Y submenu. These x/y coordinates will remain stable for this User gamut until they are 
changed again via either menu. Values displayed in the Color Saturation menu, will fluctuate as you use the 
projector, and will be different when you return to this menu in the future. These floating changes do not affect 
the x/y coordinates or gamut.
BLACK LEVEL BLENDING - Submenu
Similar to Edge Blending, Black Level Blending allows you to adjust the black level intensity of multiple 
adjacent projected images to create one large seamless display. 
NOTE: Blinders are recommended for fixed 
installations. 
						

							3-48J Series 2.0, 2.4, and 3.0kW User Manual020-100707-01  Rev. 1   (10-2011)
Section 3: Operation
Procedure
NOTES: 1) Adjust white levels before adjusting black levels. 2) The zones in BLB menu correspond to the Edge 
Blend zones. If a given Edge Blend zone width is set to 0 (i.e. no blend on that side) then the corresponding 
BLB zone is disabled. It only becomes accessible when that Edge Blend zone is active.
1. Start with two projectors. In the Black Level Blending submenu, enable black blending by selecting 
Standard for each projector.
2. Select the black test pattern for both projectors from the Geometry and Color submenu.
3. Working with one projector at a time, use the center brightness slide bar to adjust the center brightness 
(brightness of the non-blended region) so that the center intensity matches that of the brightest blended 
region (the center of all images when blending a 2 x 2 display is the target area).
4. You can select which of the next four options, Top, Bottom, Left, Right, to use depending on which edge 
of the projector you are working with has been edge blended. The blend width can be adjusted to line up 
properly but by default it corresponds to the edge blending setting determined for that edge. 
5. The brightness and black hues of the blended region can be adjusted in more detail in case fine-tuning is 
needed (may be only necessary for blending a 2 x 2 projector display because blending differs for the sides 
and center).
Default Color Adjustments
The value selected is the default to be used by the system during auto setup or initial detection of a new source. 
Refer to 3.8 Configuration - Adjusting System Parameters and Advanced Controls>3.8.8 GEOMETRY AND 
COLOR - Submenu, Color Adjustments by X,Y for description.
TILING SETUP - Submenu
Image tiling allows a single input image to be displayed, spread over multiple screens, with each screen 
displaying a fraction of the image. The image is displayed by the m×n array of projectors, where m is the 
number of rows (1-3) and n is the number of columns (1-3). This allows the following arrays to be set up: 
1x2, 2x1, 1x3, 3x1, 2x2, 2x3, 3x2, 3x3. 
NOTE: Maximum array size 3x3 with SIPC and 2x2 with DIPC.
Projectors are numbered from left to right (left column = 1), and from top to bottom (Top row = 1).
Examples: 
						

							Section 3: Operation
J Series 2.0, 2.4, and 3.0kW User Manual3-49020-100707-01  Rev. 1  (10-2011)
On each projector you must set the following:
The tiling array size - set the total rows and total columns. This setting will be the same on all the projec-
tors in the array. 
The relative location of the projector within the array - set the row number and column number for each 
projector
Enable Tiling - Tiling can be enabled or disabled without losing any of the above settings.
The features that act differently when Tiling is enabled are:
The PIP border is disabled
Cascading menus are turned off
Menus show only 5 items, with a scroll bar to allow the rest of the menu items to be reached.
Projector source switching in the array is not synchronized. Therefore some latency can be seen from when 
the commands are issued to each projector, causing switching to not be as seamless when in a tiling config-
uration. When using loop-through via the Twin HDMI Input Card to distribute a signal to the tiling array, 
additional latency in the switching can occur during HDCP repeater negotiations with the source player.
HINT: When the FUNC+HELP key combination is pressed, the tiling settings will be cleared.
NOTE: Tiled warps/keystones can be enabled through Christie TWIST 1.6; Refer to the Christie TWIST User 
Manual.
3.8.9 DIAGNOSTICS & CALIBRATION - Submenu
• TEST PATTERN
 Select the desired internal test pattern to display, or select OFF to turn off a test pattern. Alternatively, use the 
T
EST key for cycling through test patterns.
• GREY LEVEL
This will set the level of grey for displaying in the full grey field test pattern.
• FREEZE IMAGE
Enter a check mark to freeze (stop) an image on a single frame. Use this diagnostic tool to examine in detail a 
still version of an incoming image that cannot be “frozen” at the source. For example, in moving images it is 
sometimes difficult to observe artifacts such as external de-interlacing/resizing and signal noise. Remove the 
checkmark to return to normal.
• COLOR ENABLED
Select which color(s) you want to see. Use this while working with color temperature, input levels or other 
special setup parameters. Colors can be enabled/disabled by entering the corresponding function code listed on 
the back of the standard remote keypad.
• INPUT PEAK DETECTOR
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 grey. When used with a 16-
step greyscale pattern in which the two 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 then display correct blacks and whites without crushing or washing 
out. 
NOTE: If using Peak Detector with PIP, both images must have the same color space.

Section 3: Operation
• 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 greyscale.
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.
• TEST 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.
•CALIBRATE LITELOC 
The LiteLoc calibration process must be run to calibrate the LiteLoc sensor on all model types. “Constant 
Intensity” mode cannot operate correctly if the calibration has not been performed. 
NOTE: The shutter will 
close for the duration of the calibration, and will automatically open again when the calibration is complete.
3.8.10 SERVICE- Submenu
Access restricted to Christie accredited service technicians.
3.8.11 OPTION CARD SETTINGS - Submenu
Allows adjustment of any settings specific to each option card that is currently installed in the projector.  Refer 
to Configuration - Option Card Settings Appendix A: Menu Tree.

3.9 Lamp Menu
LAMP MODE
Determines how the lamp power and 
intensity are controlled. If Maximum 
Brightness is selected, the lamp burns 
as brightly as possible. Select Constant 
Intensity mode to maintain a specific 
brightness level over time. As the lamp 
ages, the projector will increase power 
as needed, to closely maintain the required output from the lamp. Select Constant Power to specify the power 
level supplied to the lamp. Both Constant Intensity and Constant Power modes extend lamp life. 
NOTES: 1) 
Constant Intensity mode, use the Intensity slidebar to adjust brightness. 
2) Constant Intensity mode cannot 
operate correctly if the LiteLoc calibration has not been performed.
POWER
Sets the lamp power in Watts. The Power control represents the amount of power sent to the lamp. Power 
increases when operating in Intensity mode, until it reaches its maximum. The value remains stable when in 
Max Brightness or Power mode. If using Power mode, setting a lower power level reduces brightness and 
extends lamp life.
INTENSITY 
Adjusts the lamp intensity to the required % of full. This value is used as a target value by the LiteLOC 
system to maintain constant intensity. 
OPTICAL APERTURE 
Controls the diameter of the light beam passing through the system. With a fully open aperture (slide bar 
default of “0”), the maximum amount of light passes through for maximum image brightness. To reduce the 
aperture diameter and maximize contrast ratio, increase the slide bar setting. 
NOTE: Performance of the 
aperture depends on the lens in use.
WARN WHEN LAMP REACHES (HOURS) 
Allows the maximum number of hours (threshold) to be set for lamp usage. When the threshold (set number of 
hours) is reached a warning message displays on the status system, indicating that the lamp should be changed. 
This setting is  user-defined only, has no bearing on lamp warranty, and is not tied to actual lamp life in any 
way. The default setting is 0, which means that the feature is off, and no warning will be generated. 
LAMP s/n
Records the lamp serial number. This will apply the serial number to the current lamp statistics file. It will not 
perform the archiving as done by the CHANGE LAMP function. 
						

							3-52J Series 2.0, 2.4, and 3.0kW User Manual020-100707-01  Rev. 1   (10-2011)
Section 3: Operation
CHANGE LAMP - Submenu
Initiates the lamp change process and allows the serial number of the new lamp to be entered.
Lamp serial numbers are used for keeping statistics on each lamp. Entering of serial numbers is optional, but is 
recommended. 
When using this function, the statistics from the previous lamp are archived, and statistics for the new lamp are 
tracked. If this function is not used, statistics are accumulated (combined) for both the new and old lamps.
LAMP HISTORY
Lists the serial number and the number of hours logged for the lamp (current and previously)  installed in the 
projector. The current lamp appears at the bottom of the list. This entry is added automatically when you record 
a new serial number during the lamp change process. See CHANGE LAMP - Submenu.
3.10 Input Switching & PIP Menu
Use the Input Switching & PIP menu to 
enable and define how you want to use PIP.
NOTE: To control the primary image, access 
all picture controls through the Main menu. 
To control the secondary (PIP) image, access 
picture controls through the Input Switching 
& Picture-in-Picture menu.
MAIN INPUT 
From the list of active inputs, select one to be 
used as the primary or main image.
PIP INPUT 
From the list of active inputs, select one to be used as the secondary or PIP.
SWAP MAIN & PIP INPUTS 
Toggle the current PIP relationship so that the primary (main) image becomes secondary (PIP), and the 
secondary image becomes primary. Swapping is available only when PIP is enabled. 
NOTE: You may 
experience a slight delay when swapping the Primary and Secondary images.
PIP ENABLE 
 Short cut: Press PIP on the Remote if menu not 
present.
Toggle between displaying two sources at once 
(Main and PIP images) and the primary or main 
source only. This check box turns the secondary 
source on and off.

PIP WINDOWS OPTIONS - Submenu 
•PIP POSITION PRESETS 
Select a preset location and size of the PIP window. While in split screen mode, several channel controls that 
resize image will be disabled. These controls are size, H-Position and V-Position.
•PIP WINDOW SIZE 
Sets the width of the PIP window in pixels. The active portion of the input signal, as determined by blanking 
controls, will be scaled to fit into the PIP window. The height of the PIP window will be set to maintain the 
aspect ratio of the image being captured, as determined by the Vertical Stretch control. 
• PIP H-POSITION
 Sets the center position of the Picture-In-Picture window on the screen.  
•PIP V-POSITION 
 Sets the center position of the Picture-In-Picture window on the screen. 
•PIP BORDER WIDTH 
Specify how thick the Picture-In-Picture border should be. Setting the control to zero disables the border. 
NOTE: The thickness of the border is proportional to the size of the PIP image. Larger windows will have 
larger borders.
•PIP BORDER COLOR 
Select the color of the optional border around the Picture-In-Picture image.
PIP SIZE & POSITION - Submenu
Most controls in the PIP Size and Position menu adjust the PIP (secondary) image in the same fashion as their 
counterparts in the main Size and Position menu. 
•POSITION PRESETS 
Set the location of the PIP (secondary) image in the display.
PIP IMAGE SETTINGS - Submenu
The controls adjust the PIP (secondary) image in the same fashion as their counter parts in the main Image 
Settings menu. 
NOTE: Refer to 3.7 Image Settings Menu for details of Contrast to Advanced Image Settings.
FADE TIME
Sets the amount of time (in seconds) it takes to fade between images on a source switch and fades in the PIP 
image.
FRAME LOCKING
When the selection is set to Frame Lock, output image frames are locked to the input. When locked, the 
output is always locked to the primary input, never the secondary image. Select Free Run and this will set the 
output to close to 60Hz for all sources.  
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 select from, the order is 
based on slot, followed by inputs on that slot.

Section 3: Operation
HDMI OUTPUT LOOP SOURCE
Configure the HDMI output options. 
Select Direct Loop to directly pass-through the HDMI input signals (from the same Twin HDMI Input Card). 
The Input1 signal is looped to Output1 and the Input2 is looped to Output2. 
Select Main/Secondary Loop to loop the Main & secondary video to the outputs (regardless of which card 
these signal originate from). The Main video signal is looped to Output1 and the Secondary video signal is 
looped to Output2. 
Select Disable to shut off the HDMI outputs completely.
STANDBY ACTIVE LOOP-THROUGH 
Enable this checkbox in situations where a Twin HDMI Input card is being used to loop signals out to another 
projector. Standby Active Loop-Through ensures that video signals continue to be looped out when the 
projector enters standby power mode. 
NOTE: When the projector is in standby mode (and Standby Active 
Loop-Through is selected), limited channel control is available - inputs can be switched, perform auto setup 
and some limited input settings can be modified.
3.11 Status
The read-only Status menu lists a variety of details about the standard and optional components currently 
detected in the projector. Refer to the Status menu for versions of hardware and software installed, the type 
(size) of lamp, the hours logged in total and for a specific period (such as a rental period), and for your 
projector model name and serial number. In addition, the Status menu identifies the current channel, its 
location, its frequencies and other details.
3.12 Using Multiple Projectors
IMPORTANT! When working with more than two projectors, work left to right, top to bottom.
When an installation requires multiple projectors, use the RS-232 serial ports to daisy chain the units together 
and control the group with a single keypad or a computer/controller connected to the first projector. In such a 
network, you can select to broadcast commands to the entire group, or use the P
ROJ key as desired to limit 
responses to an individual projector. 
Alternatively, you may want to add projectors to a hub on an Ethernet network. See Figure 2-41 Mixed 
Network for full routing details.
Matching Colors in Multiple Screens
In a multiple-projector wall, you will likely want to precisely match color and intensity from image-to-image 
so that the full wall is as uniform as possible.
