Advanced Image Settings — SUBMENU 
Use the Advanced Image Settings submenu 
to make the adjustments necessary for lesser-
used but more specialized applications on 
your projector. 
GAMMA TABLE: This control applies a 
default video, graphics or simple gamma 
table or “curve” to your images, controlling 
the intensity of mid-level colors and 
producing maximum contrast, brightness and 
color performance. As shown at right, the graphics curve is a modified power curve 
that will show more detail in darker areas of the projected content while the video 
curve has a linear segment near black to compensate for increased black levels typical 
of video signals. A simple gamma curve is a 
true power curve that does not alter the 
contrast or the intensity of mid-level colors. 
Although the projector automatically applies 
either the graphics or video curve according to 
what type of incoming signal is detected, in 
some cases you may wish to override this 
default and use graphics gamma for a video 
source or video gamma for a graphics source. Alternatively, if neither default is ideal, 
you may prefer to apply the simple (non-optimized) gamma curve or a user-defined 
custom gamma curve that has been created externally, named, and downloaded to the 
projector (requires separate PC-based Arbitrary Gamma
 and KoRE Librarian software 
applications). If any of these special user curves have been installed, their names will 
appear in the Gamma Table pull-down list. 
Keep in mind that any Gamma Table choice sets the related Gamma value (shown in 
the Image Settings menu) to a 2.2 default, where it can be fine-tuned as desired. 
Different values (1-3) here indicate that the original gamma table has been adjusted 
with either the Gamma slide bar or direct key. 
NOTES: 1) If no user curves have been defined and downloaded to projector memory, 
only the 2.2 default gamma curve is available here – adjust as desired using gamma 
in the main Image Settings menu. 2) Some graphic material will look best with the 
video setting while some video material is best with the graphic setting. 
SELECT COLOR ADJUSTMENT: In “Select Color Adjustment”, 
choose an overall color palette for all images. The “Max 
Drives” factory default simply drives all three colors at their 
maximum level so that they are fully on and cannot be 
changed. The two other pre-defined color adjustment 
choices—SD Video and HD Video—apply a color gamut 
optimized for video sources (standard or high-definition). 
Alternatively, you can specify a color temperature. This 
enables the adjacent Color Temperature slide bar and applies 
its current setting (default = 6500K). If none of the pre-
defined “Select Color Adjustment” options or color temperatures suits your 
application, select one of four color gamuts previously defined by a user (User 1, 2, 3, 
4). A “User” option applies a customized color performance in which the user has

precisely set the hue and intensity of each color component in the Color Adjustment 
by X/Y or Color Saturation submenus. It is most often needed with multiple-projector 
applications. Select the color adjustment producing the best color accuracy for your 
application and installation. 
To configure a “User” color adjustment (gamut), use either the Color Adjustment by 
X/Y or Color Saturation submenu. 
NOTES: 1) “Color Temperature” defaults to 6500K until changed. All four “User” 
options default to SD Video unless the user has redefined them. 2) Factory-defined 
color primaries, which ensure consistent color gamut from projector-to-projector, can 
be calibrated in the Service menu only. If you suspect alteration, the factory settings 
can be recovered with selection of “Reset to Factory Defaults?” in the Color Primary 
Settings submenu within the Service menu (password-protected). 
COLOR TEMPERATURE — Adjust to apply a specific and accurate color temperature to 
all displays. Color temperatures are expressed in degrees Kelvin (3200-9300K), and 
utilize different combinations of the projector’s original native color primaries to 
produce a “coloration” or cast (reddish or bluish) in images—the lower the 
temperature, the more reddish the cast; the higher the temperature, the more bluish the 
cast. Note that the slide bar is enabled only if you have a source connected and have 
selected “Color Temperature” in the adjacent “Select Color Adjustment” pull-down 
list in the Advanced Image Settings menu. 
OPTICAL APERTURE - The optical aperture inside the projector 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 brightness 
in your images. Increase the slide bar setting to reduce the aperture diameter and 
maximize contrast ratio instead. Performance of aperture depends on the lens in use. 
NOTE: Optical Aperture also appears in the lamp menu. 
RESERVED - No function.

Simulation 3D — SUBMENU OF ADVANCED IMAGE SETTINGS 
Use the options in the Simulation 3D 
menu to make the timing adjustments 
necessary for realistic simulation and 
3D images. 
NOTES: 1) Available in SXGA+ and 
HD Mirage and Matrix projectors 
only. 2) For complete 3D application 
notes, refer to the separate Using 3D 
in Mirage manual provided with the 
Mirage projector. 
FRAME DELAY MONITOR — This slide 
bar monitors the latency between 
input and output. For best results, the 
bar width and value should remain 
fairly constant, indicating that timing 
of input and output frames is locked; 
the Frame Delay Monitor value 
should stay within 5-10 lines or so of 
the Frame Delay setting. If a frame is 
lost or “dropped”, the bar will move 
suddenly and the values will change, indicating that the frame input is no longer equal 
to the output. 
NOTE: See separate Using 3D in Mirage manual provided for more information. 
FRAME DELAY — Set the number of lines delayed between the input signal and its 
appearance on screen, keeping in mind that projector processing always adds one 
frame of delay to the frame delay setting. For applications such as simulation, where 
the feeling of “real time” image response is a priority, a minimum setting is usually 
preferable. For projectors capable of 3D (stereographic) applications where alternating 
left-right frames must be synchronized with the corresponding L/R shutters in 3D 
glasses, a total frame delay setting of two (or multiple of two) may be more useful. If 
set too high or low, frame locking will not be possible—most sources require 
approximately 50 lines of delay to ensure frame locking. 
NOTE: See separate Using 3D in Mirage
 manual provided for more information.  
DARK INTERVAL (Mirage models only) — Adjust Dark Interval to artificially increase 
the amount of dark time between displayed frames for stereographic 3D images. 
Higher settings provide more time for shutters in 3D glasses to open/close, ensuring 
that each eye sees the full display intended for it. Symptoms of cross talk and/or color 
artifacts can indicate need for adjustment. The Dark Interval range of adjustment 
depends on the vertical frequency of your source—the higher the frequency, the 
smaller the range. 
NOTE: See separate Using 3D in Mirage
 manual provided for more information. 
ACCUFRAME (Matrix models only) – Increasing the AccuFrame value will reduce the 
artifacts related to fast motion in simulation content. Symptoms of blurry objects or 
loss of apparent detail may indicate a need for this value to be adjusted.

020-100001-01 Rev. 01 (04/07)  3-35. 
 
NOTE: If increasing AccuFrame does not improve image quality, reduce the value to 
0. Increasing AccuFrame may increase ‘flicker’ of the display. 
 
3D STEREO SYNC LOCKING  (Mirage models only) — This option defines 1) whether 
or not the incoming stereographic 3D signal locks to the vertical sync output so that 
signals are synchronized, and 2) whether or not the 3D frames must be inverted, i.e. 
swapped left-with-right. The correct setting ensures that the projector’s 3D display of 
left/right frames is synchronized with the rest of the 3D system components so that the 
intended eye sees the left/right image data. Select the option corresponding to your 3D 
source connections and timing, and use only if the Mirage 3D Stereo Sync Cable is 
connected between the projector’s GPIO port and a server. Keep this adjustment OFF 
(default) when you are not using the Mirage 3D Stereo Sync Cable. 
  
With your sync cable, Z-screen and, if desired, emitter connected as described in the 
Using 3D in Mirage
 manual, select the option suited to your 3D configuration (see 
above). If Frame Delay is two (or 0), do not invert; if frame delay is one or three, 
invert. Generally, an “Unlocked” setting is synchronized with the incoming L/R signal 
rather than the vertical sync output, and may be needed only with multi-projector 
installations in which the vertical sync outputs vary. 
NOTE: See separate Using 3D in Mirage
 manual provided for more information. 
3D STEREO SYNC SELECT 
(Mirage models only) — 
Define which of the 
Mirage 3D Stereo Sync 
Cable’s input connecters 
is routed from your server. 
Use only if the cable is present.  
3D STEREO SYNC DELAY (Mirage models only) — Set when the L/R frames begin, 
defining the best reference point for synchronizing the display with your glasses. 
Proper adjustment of this delay should eliminate cross talk and odd colors caused by 
timing differences between the glasses and the projected display. Use this slide bar 
only if the Mirage 3D Stereo Sync Cable is connected between the projector’s GPIO 
port and a server. Slide bar values indicate the number of lines that are delayed. 
FRAME LOCK ENABLE — This option allows the projector to control the output frame 
timing based on the input signal. The locked option forces (if possible) the output 
image to be phase locked to the input frames. Rate Matched means that the output 
runs at close to the input frequency but isn’t locked to it so the output will drift in 
phase relative to the output. Free Run forces the output to run at a 60Hz frame rate.  
NOTE: 1) See separate Using 3D in Mirage
 manual provided for additional 
information.

— SUBMENU 
MOTION FILTER — 
This control is most useful for smoothing out moving images from 
interlaced sources. In most cases the proper Motion Filter setting is 
automatically determined according to the type of incoming source 
signal. However, if your source is jittery and/or tearing you may wish 
to “force” a setting to ensure stable processing for this source—if 
desired, override the default “Auto” setting by selecting the appropriate 
motion filter:  
1. 
AUTO: The projector will automatically use the correct motion filter according to 
the incoming signal. 
2. 
STILL: For static images with no motion, such as graphics from a CD. 
3. 
MOTION: For video images that did not originate from film, or for moving 
computer-generated images. 
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.
 
3D SOURCE 
— When using a Mirage projector with HD resolution, a checkbox option 
called 3D Source will be added to the bottom of the Advanced Image Settings menu. 
This checkbox must be set by the user for all new 3D sources, and cleared for all new 
non-3D sources (default setting is checked).  Once set, this value will be maintained 
for that source for all future uses. This option is also available under the Simulation 
3D menu in Mirage HD projectors only.

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 being used. 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. 
Reserved 
No function. 
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.

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” slide bars 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 
Channel 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 Channel 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 SLIDE BARS — Enter a checkmark to superimpose a small slide bar over the 
current image whenever an adjustable parameter is selected directly with a key such as 
Contrast or
 Bright. If “Display Slide bars” is unchecked, these slide bars can still be 
accessed, but will be hidden during adjustment. This option does not affect slide bars 
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 “Serial Ports” to receive messages via RS232 or RS422 serial 
communication only. To hide error message displays, such as during shows and 
presentations, select “Off” or “Serial Ports”. 
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. 
• Start-up Only – The splash screen logo appears at projector start-up only. 
 
  
						

							 Section 3: Operation 
020-100001-01 Rev. 01 (04/07)  3-39. 
• Start-up And No Signal – A splash screen appears at start-up 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, 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 eight 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 the menu shown above). Numerical 
identity for projectors enables you to communicate with a single projector within a 
multiple-projector application (see also 
Proj key in 3.2, Using the Keypads). If you 
make a mistake in assigning or changing the projector number, press 
Ex it to cancel.  
NOTE: When multiple projectors are being used and you want to adjust the color and 
edge blending settings for individual projectors to create one seamless image, you 
must assign different numbers for each projector to allow toggling back and forth 
between projectors while adjustments are being made.  
Network Routing 
NOTE:  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 3.8A, RS422 controls only the projector to which it is connected. In 
Figure 3.8B, either RS232 or RS422 will control the network.

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) 
NOTE:  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. 
  
						

							 Section 3: Operation 
020-100001-01 Rev. 01 (04/07)  3-41. 
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. 
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. It is highly recommended not to use a port # below 1000, as these 
ports are typically reserved for and used by common IP applications. 
SUBNET MASK AND DEFAULT GATEWAY: The Subnet Mask and Default Gateway are 
automatically assigned when DHCP is enabled. If a static IP is being used, the IP must 
be assigned first since the projector estimates the subnet mask after the IP is entered. 
The Default Gateway is an optional router device used to send and receive data 
outside the subnet. 
ArtNet Interface Settings 
— SUBMENU  
ArtNet is an Ethernet communication protocol that was developed by Artistic License. 
It is used for controlling lighting/staging equipment from a lighting console or PC 
application. It is based on the popular DMX512 control protocol. 
ArtNet SUBNET: This is the highest level address for a device. Typically it is set to 0. 
ArtNet UNIVERSE: Each packet of data is broadcasted to all devices plugged into a 
universe (up to 512 devices/channels). 
ArtNet CHANNEL: There are 512 channels per universe. This control allows you to 
specify the starting channel for this projector.  
ArtNet ADVANCED MODE: When this setting is enabled, each projector listens for data 
on 64 channels starting with the base channel. When advanced mode is not in use, the 
projector only listens on 10 channels. You can squeeze more devices per universe 
when the projector uses fewer channels.  
NOTE: The additional 54 functions are not currently implemented and are reserved 
for future use. 
ArtNet BASE CHANNEL: When advanced mode is enabled, the projector listens to data 
on 64 consecutive channels, or 10 consecutive channels when advanced mode is not 
enabled. The projector processes requests that come on either 10 or 64 consecutive 
channels beginning with the ‘base channel’ defined here. The requests implement the 
following functions:
