4. FILM: For video images that originated from film. This will optimize image 
quality and stability. 
 
FILM MODE THRESHOLD — This setting determines how sensitively the projector can 
detect if an incoming video signal originated from film or not. It should not require 
adjustment. 
DETAIL THRESHOLD — Use “Detail Threshold” to define at what frequency level the 
“Detail” control will begin to magnify high frequencies, which adds details back into 
the image. Raise the threshold to ignore more of these high frequencies, and lower the 
threshold to magnify more of these frequencies. A setting of “0”, for example, means 
no noise will be ignored and all will be magnified. An ideal detail threshold is one in 
which high frequencies that are causing objectionable noise are not magnified when 
using “Detail”, but frequencies which can help sharpen an overly-soft image are 
magnified.
 
 
Use the Configuration menu 
to define general operating 
parameters and 
communications with other 
projectors and equipment, and 
to access other advanced 
processing and image 
adjustments affecting overall 
performance. In addition, the 
Configuration menu provides 
access to diagnostics, 
calibration tools and the 
Service submenu (password-
protected). 
Keep in mind that settings in the Configuration menu (and its submenus) are typically 
“global” settings applied regardless of the type of source your are using. This 
characteristic is identified with the 
 (globe) icon alongside the option. 
NOTE: The Configuration menu is recommended for experienced users/technicians 
only. 
The first six options in the Configuration menu are explained below: 
Language 
Choose from available languages to use in the projector’s menus. The change will 
take effect immediately. 
Image Orientation 
Set the orientation of the image according to the orientation of your projector. If the 
setting is incorrect, projected images will be reversed and/or upside down.

Auto Power-up 
Enter a checkmark to enable the projector to automatically power up after losing 
power due to a power failure or due to unplugging the projector during operation. 
Note that unsaved display adjustments may be lost. 
Set Date & Time 
Enter/read the current year-month-day and hour-minute-second. Changes here reset 
the projector’s real-time clock. 
Menu Preferences 
— SUBMENU 
Adjust the appearance, content 
and/or location of on-screen 
menus and messages. 
LARGE MENU FONT — Enter a 
checkmark to enlarge menus and 
their text. You may have to adjust 
“Menu Location” to accommodate 
the increased menu area. 
MENU LOCATION — Use the pull-down list to choose a pre-defined default or 
customized location for the display of all on-screen menus.  
To create a custom menu location quickly, choose a preset that is closest to the desired 
location. Then adjust “Horizontal Shift” and “Vertical Shift” slidebars to move the 
menu to the desired location. Avoid locations too close to a corner or edge to prevent 
cropping of larger menus. 
HORIZONTAL SHIFT AND VERTICAL SHIFT — Shift your menus as desired, creating a 
customized menu location. 
DISPLAY CHANNEL LIST — Enter a checkmark if you want to see a scrollable channel 
list whenever you press 
C han nel from your presentation. Channels marked with a list icon 
 in the Channel Setup menu will appear here. The “Display Channel List” option 
also enables on-screen feedback when using the C han nel key. If you prefer to hide the 
channel list and input dialog box while switching channels and sources during a 
presentation clear the checkbox. 
NOTE: The Channel List and input dialog box cannot be hidden during use of the 
menus. 
DISPLAY SLIDEBARS — Enter a checkmark to superimpose a small slidebar over the 
current image whenever an adjustable parameter is selected directly with a key such as 
Contra st or
 Bright. If “Display Slidebars” is unchecked, these slidebars can still be 
accessed, but will be hidden during adjustment. This option does not affect slidebars 
in menus. 
DISPLAY ERROR MESSAGES — Choose how you want to be notified of errors detected 
in either the incoming signal or projector.
 Select “Screen” or “All” (default) to see 
brief on-screen messages. This is particularly recommended during setup or testing of 
the projector. Or select “RS232” to receive messages via RS232 (or RS422) serial 
communication only. To hide error message displays, such as during shows and 
presentations, select “Off” or “RS232”.

SPLASH SCREEN SETUP —Use the Splash Screen to choose when you would like to 
display a special introductory splash screen image, such as your company logo, 
graphic or message. 
• Always Off = A splash screen never appears 
• Always On = A splash screen is always on behind the current display 
image, similar to wallpaper. 
• Startup Only – The splash screen logo appears at projector startup only. 
• Startup And No Signal – A splash screen appears at startup only if there is 
no source signal. 
 
To replace the default “Christie logo” splash screen (or other) with one of your own, 
use KoRE Librarian to download the desired .bmp to the projector. This will 
overwrite the current splash screen content in projector memory. 
Settings in the Communications 
submenu define and control how 
single or multiple projectors are 
linked with each other and with a 
controlling device. 
Baud Rates 
The baud rate setting determines 
the speed of communication to 
and from the projector on the 
RS232 or RS422 links. The 
maximum rate for the RS232 is 
115200; for RS422 it is 19200. 
Set the baud rate to match that of your controlling device, such as your PC. If you are 
unsure about what baud rate to choose, refer to the documentation for the controlling 
device. In an existing network of projectors, if you discover that a projector has a 
different baud rate, make sure to use the pull-down list and select the correct baud rate 
using the 
 key—do not just scroll this control with  or  keys. Serial 
communication is always 8 data bits, no parity. 
Projector 
Enter a three-digit number (such as “001”) to assign or change a number to the 
projector currently in use. If the current projector already has a number assigned, that 
number will appear here (for example, “004” in Figure 3.17. above). Numerical 
identity for projectors enables you to communicate with a single projector within a 
multiple-projector application (see also 
Pr o j key in 3.2, Using the Keypads). If you 
make a mistake in assigning or changing the projector number, press 
Ex i t to cancel. 
Network Routing 
NOTES: 1) Not applicable for stand-alone projectors or simple serial networks with 
only one type of controller and linking.

SEPARATE: Select “Separate” (factory default) to keep RS232, RS422 and Ethernet 
messages on their respective paths instead of being broadcast to the other types of 
ports. In Figure 3.18A, RS422 controls only the projector to which it is connected. In 
Figure 3.18B, either RS232 or RS422 will control the network. 
 
Figure 3.18. Using the “Network Routing” Option 
RS232 AND RS422 JOINED: Messages originating from an RS232 or RS422 controller 
will be relayed to all RS232or RS422 ports. Any Ethernet communication, however, 
will not. 
RS232 AND ETHERNET JOINED: Messages to and from the RS232 ports will also be 
relayed to the Ethernet port, and vice versa. Any RS422 communications will be 
isolated. 
ALL JOINED: All messages reach all ports, regardless of type. 
Ethernet Settings 
(SUBMENU) 
NOTES: 1) Recommended for network administrators only. 
DHCP: Enable this checkbox if you want a DHCP server to automatically change the 
projector’s default IP address (0.0.0.0) to one that is valid and unique for use on the 
current Ethernet network. On networks without a DHCP server, or to simply override 
the automatic DHCP server function, delete the checkmark and enter the new “IP 
Address” settings desired. Remember that only a 0.0.0.0 address will trigger the 
DHCP addressing service, and only when the DHCP checkbox is enabled. 
 
IP ADDRESS: Enter a valid and unique IP address for use on the network to which the 
projector is currently connected. This address will overwrite any previous IP address 
such as the projector’s factory-defined default (0.0.0.0), or one that has been assigned 
by a DHCP server or other user. It takes approximately 10 seconds for the projector to 
respond at its new address.  
						

							Section 3: Operation 
 
  
 User’s Manual     3-39. 
PORT: On some Ethernet networks, firewall restrictions may require that the port 
number of the projector be changed from its default of 3002. If so, enter a new valid 
port number here. 
Broadcast Key 
Enter a checkmark if you want keypad commands sent to one projector to be relayed 
to all projectors in a serial network. Note that the 
Pr o j key will temporarily “override” 
the effect of a broadcast setting and allow you to control a specific projector when 
necessary. Disable the setting for all but one (any) projector in a network. 
Backlight 
Toggle to turn the built-in keypad backlighting on and off. 
Front IR / Back IR 
As needed for your application, set to “on” so that the front and/or rear IR sensor 
locations on the projector respond to the IR keypad. Set to “off” to disable. 
To disable both IR sensors, you cannot use the IR remote keypad to select the second 
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you 
are using it. Instead, use either the built-in keypad or a wired remote (optional) to set 
the remaining active sensor to 
OFF. The projector will no longer respond to an IR 
remote keypad. 
Wired Keypad 
The wired keypad is ON by default to when connected to the rear of the projector. The 
projector will then respond to incoming commands from this port. To disable the 
wired keypad, you must use a different keypad—the built-in or an IR remote 
keypad—to select “off”. This safeguard prevents you from accidentally disabling the 
wired keypad during use. 
In the Configuration menu, select 
the Geometry and Color submenu 
when you need to modify overall 
color performance and/or image 
geometry for all sources. 
Test Pattern 
Choose the desired internal test 
pattern, or select OFF to turn off a 
test pattern. Alternatively, use the 
Te s t key for cycling through test patterns. 
Keystone 
NOTE: If the optional ChristieTWIST module is installed, this option is Keystone and 
Warping, and activates a submenu for defining custom image shapes. Please refer to 
documentation included with your Christie TWIST module. 
Use to correct a keystoned image shape in which both sides of your image are inclined 
toward the top or bottom edge. Keystone is typically caused by tilting the projector in 
relation to the screen, so that the lens surface and screen are no longer parallel to each 
other.    System Configuration

Brightness Uniformity — SUBMENU 
Brightness Uniformity provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
Enable” checkbox to access a multitude of adjustments for critical color light output 
control in specific areas throughout the image. Your settings apply as long as the 
“Uniformity Enable” checkbox is enabled and you are using a “User” color 
temperature defined by the Brightness Uniformity controls. To disable the Brightness 
Uniformity function, delete the “Uniformity Enable” checkmark. 
NOTE: See also 3.10, Using Multiple Projectors for the complete step-by-step 
procedure for achieving uniform brightness in adjacent displays.  
Edge Blending 
— SUBMENU 
The Edge Blending submenu provides a range of controls for smoothing together the 
overlapping bright edges of multiple adjacent projected images to create a single 
larger “seamless” image. These controls, which primarily affect whitelevels, are 
typically used in conjunction with mechanical lens blinders (optional), which are 
installed on the front of the projector and which primarily affect blacklevels. NOTE: 
There is a center line (both horizontal and vertical) in the Edge Blending test pattern. 
The intersection of these lines is the true center of the projector’s display area. 
NOTE: See also 3.10, Using Multiple Projectors.  
Color Adjustments by X/Y, and Color Saturation — 
SUBMENUS 
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or 
“gamut”. Sometimes known as Comprehensive 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. If you suspect 
alteration of these defaults, 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 3 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. 
 
Figure 3.20. Color Gamut Choices  
						

							Section 3: Operation 
 
  
 User’s Manual     3-41. 
DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre-
defined “Select Color Adjustment” options exactly 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 that 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. 
• Color Adjustments by X,Y
 — Enter known x/y coordinates from the 
chromaticity graph. 
• Color Saturation
 — Adjust color slidebars 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”). 
COLOR ADJUSTMENT BY X,Y: Use 
this submenu if you want 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 
3.21)—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 slidebars 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.

NOTE: Keep new x,y coordinates within the original color gamut triangle shown 
here. 
PROCEDURE FOR X,Y ADJUSTMENTS:  See 3.10, Using Multiple Projectors. 
COLOR SATURATION: Use this 
submenu if you do not have 
specific color coordinates in mind 
and will simply 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—it is just a 
different interface. 
Adjust the hue of each primary 
color (red, green, blue, and white) 
by using more or less of it in 
relation to the other colors. 
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, however, will likely fluctuate as you use the 
projector, and will be different when you return to this menu at some point in the 
future. These floating changes do not affect the x/y coordinates or gamut.

Test Pattern 
Choose the desired internal test 
pattern to display, or select OFF 
to turn off a test pattern. 
Alternatively, use the 
Te s t key 
for cycling through test patterns. 
NOTE: There is a center line 
(both horizontal and vertical) in 
the Edge Blending test pattern. 
The intersection of these lines is 
the true center of the projector’s 
display area. 
Test Pattern Grey Level 
Set the desired level of grey for displaying in the full gray field test pattern. 
Freeze Image 
Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is 
useful if you need 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 deinterlacing/resizing and signal noise. Remove the 
checkmark to return back to normal. 
Color Enable 
Select which color or colors you want to see. This is useful while working with color 
temperature, input levels or other special setup parameters. Colors can also be 
enabled/disabled by entering the corresponding function code listed on the back of the 
standard remote keypad. 
Odd Pixel Adjustment 
NOTES: 1) Factory-set and rarely required by user. 2) Source must be >90 MHz. 
When using certain RGB sources, you may need to adjust the normal gain or offset of 
odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide) 
“checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Using the 
Level Detector simplifies this process (see Figure 3.24): 
1.  Use an external analog native-sized continuous grayscale test pattern with at 
least 256-levels. 
2.  Turn “Level Detector” on. 
3.  Set “Level Value” to ~200. The image should now be black-and-white (or 
black-and-one color, if you use “Color Enable” function). 
4. Adjust offset. Half of the pixels will move, the other half will not. 
5.  Adjust until the two transition regions overlap. The stripe of noise will be 
minimized, defined by the value in the slidebar. 
6.  Set “Level Value” to ~800. The image should now be black-and-white. 
7.  Repeat Steps 4 and 5, but adjusting gain. 
8.  Repeat Steps 3-7 for all remaining colors. Your RGB source should now be 
OK.   System Configuration

  User’s Manual      
Two sets of values are automatically saved with these controls—one value for Input 
#1, and one for Input #2 (analog). The current set of values depends on which source 
is in use. This enables a source to be processed correctly via 2 different inputs. 
 
Figure 3.24. Using “Odd Pixel Adjustment” 
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
eliminates “1 pixel on, 1 pixel off” artifact only, not any type of larger artifacts. 
Reserved 
No function. 
Peak Detector 
The “Peak Detector” is a fast method for defining individual input levels, and can 
improve 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 two black and white bands 
are known to be at opposite edges of the image, you can watch these isolated areas 
while adjusting individual blacklevels 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. 
Level Detector 
The “Level Detector” checkbox 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. It aids in Odd Pixel Adjustment. To use: 
1.  Enable “Level Detector” and display a continuous grayscale. 
2. Set “Level Value” to near black (such as 200). 
3.  Adjust Offsets to minimize area of black stripe. 
4. Set “Level Value” to near white (such as 800). 
5.  Adjust Gains to minimize area of white stripe. 
Level Value 
Level Value defines the value to be used by the Level Detector in recognizing blacks 
and whites. See Level Detector, above.
