• FILM MODE DETECT
Enables or disables film motion detection. Film mode detect is a control that you will not need to adjust. The 
image processor automatically detects the type of input for most types of interlaced signals. i.e. 3:2, 2:2. 
However, there are cases where progressive segmented frame signals (PsF, a broadcast Sony standard) are not 
detected properly. For those cases, the de-interlacer can be forced into PsF for that channel using the Film 
Mode Detect control. 
NOTE: This is a channel control, not a system control. Film Mode Detect needs to be set 
for a specific source, all other new sources are set to Auto.
Settings Available:
• Auto (Default)
• PsF
•Off
NOTE: Off is used only where an interlaced source is improperly detected and it is not PsF type.
•CHROMA/LUMA DELAY 
Affects any incoming composite or S-video signal, delaying the luma signal (intensity) in relation to the 
chroma (color). In the image, increasing the luma delay will move luma (seen as a shadow where colors 
overlap) to the right slightly, with colors remaining in place. Decreasing this delay will move the shadow 
slightly to the left. If necessary for your current source, adjust so that no shadows occur with adjacent colors.
• SPLIT SCREEN
This control allows a snap shot of the main image to be presented on the right side or lower part of the screen, 
to allow evaluation of advanced image processing features. All resizing controls are honoured on both images. 
However, image processing controls (such as, Detail, Sharpness, Noise Reduction and Adaptive Contrast) only 
happen on the left side or top image. Changing inputs, channels or test patterns will disable this control. PIP 
operation must be disabled prior to enabling this control. 
NOTE: Split screen cannot be used in conjunction 
with either PIP or Tiling. Both PIP and Tiling must be disabled prior to enabling Split Screen control.
• RGB QUANTIZATION RANGE
This control defines the RGB quantization levels for digital DVI and HDMI inputs using the RGB colorspace. 
Typically, graphics sources use the full range of levels for the given bit depth (i.e. 8-bit, 10-bit, 12-bit) and 
consumer electronics (CE) products typically use a limited range of data within the given bit depth. This 
control must be set to limited to correct the levels for those CE products that use the limited space. This adjusts 
what is considered black and white levels in the image. As an example for 8 bit space, full range RGB uses 
levels 0(black) to 255(white). 
INPUT LEVELS - Submenu 
NOTES: 1) Because the projector 
automatically optimizes input levels for all 
but the most unusual of sources, it is 
recommended that only experienced users use 
the Input Levels submenu. 
2) Before 
beginning, check that overall contrast and 
brightness settings are near 50 and that color 
temperature is properly set up on an internal 
greyscale test pattern. 
3) Refer to 3.1.1 
Remote Keypad Commands, “AUTO”.

Section 3: Operation
Good RGB or input levels—that is, the drives and black levels for each of the three colors, red, green and 
blue—ensure that images from analog sources other than decoded video have maximum contrast without 
crushing black or white. By default (and in an “Auto Setup”), the projector automatically determines the best 
input levels by monitoring image content and adjusting the controls appropriately—further adjustment is 
typically not required to obtain proper blacks or whites. 
NOTE: This automatic adjustment requires at least 6-
12 consecutive white pixels in the image. Without these pixels, input levels may produce skewed colors, 
particularly in non-video images.
For a source exhibiting overly high black levels (typically caused by a noisy source causing black level spikes) 
use the Input Levels menu (shown above). These adjustments, serve as a calibration process compensating for 
differences in sources and cabling, to perfect the source image input levels and eliminate the “overshoot” and 
“undershoot”. 
NOTES: 1) Input Levels are of limited use with digital signals, but do offer some ability to tweak 
poorly mastered source materials. 
2) Input levels apply for the current source only, but for any color 
temperature used. 
3) Assuming that color temperature has been set up based on the internal test patterns, you 
can then set up input levels for a given source so that it matches the color temperature of the internal test 
patterns.
•AUTO INPUT LEVEL 
Use only if you are an experienced user and you have an unusual source that you feel needs further color 
temperature and/or input level adjustment. This compensates for incoming out-of-range drives (white) and 
black levels (black) that would cause “crushing” of light and dark colors in the image. After entering a 
checkmark, wait for the six slide bar values to stabilize, then delete the checkmark and exit. The Auto Input 
Level is automatically turned off upon exit from the Input Levels Menu.
•BLACK LEVELS AND DRIVES 
To check your image levels and adjust these controls:
1. Ensure overall “Contrast” and “Brightness” settings are both set to near 50. 
NOTE: Not required for 
“Auto” adjustment.
C
ONTRAST = 50 (approx.)
B
RIGHT = 50 (approx.)
2. Check the color temperature setup using an internal greyscale test pattern, making sure to obtain a neutral 
greyscale. 
NOTE: Not required for “Auto” adjustment.
3. Confirm that you are using input on an Analog BNC card or a Dual Link DVI card. Input Levels are not 
applicable for sources going through the decoder. A greyscale is recommended.
4. If black levels are too high (and/or whites are too low, which is rare), you likely have a noisy source that is 
producing skewed input levels. Enable “Auto” in the Input Levels menu. Wait for all six values to 
stabilize. Alternatively, do not use “Auto”—reduce black levels manually instead. Judge by eye and 
change one or more of the six levels as necessary to obtain proper blacks and whites. You may want to see 
only a certain color while adjusting—use the Auto Color Enable option (described below).
5. Delete the “Auto” checkmark and leave the Input Levels menu.
IMPORTANT: Do not use Input Levels to adjust color temperature. This will distort contrast and 
brightness functions as well as color temperature.
•AUTO COLOR ENABLE 
When a checkmark is present, selecting a specific black level or drive to adjust will automatically enable the 
corresponding color in the display. Delete the checkmark to see all colors, or to enable a different specific color 
through the Color Enable control.

•CLAMP LOCATION 
Brightens the image produced from certain high-resolution high-frequency graphic sources. The projector 
automatically selects the best clamp location for most sources. Use the normal Back Porch location if the 
image is either sufficiently bright or overly bright. Select Sync Tip if the image appears unusually dim, if there 
are horizontal streaks across the image, or if there is significant color drift. This moves the clamping pulse 
from the normal back porch location (which is likely too short) to the tip of the horizontal sync pulse. Tri 
Level is typically needed for an HDTV source.
•INPUT PEAK DETECTOR 
A tool to assist with defining individual input levels, enabling you to accurately set the Input Levels for any 
particular source with the appropriate image. 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 smooth greyscale pattern in which black and white 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 
black and white edges are just visible and distinguished from neighboring pixels. Images from this source will 
then display correct blacks and whites without crushing. See Figure 3-28 Adjusting Input Levels Using the 
Peak Detector (RED EXAMPLE SHOWN).
1. Display a 16 level greyscale test pattern from the desired external source, and enter a checkmark in the 
Input Peak Detector check box. 
NOTE: The Input Peak Detector will initially render the greyscale as a 
uniform grey field before adjustment or extreme crushing.
2. Display one primary color. 
NOTE: Select Auto Color Enable to ensure the correct color is displayed for 
each setting. 
3. For the current color, adjust its corresponding Black level slide bar just until a single band of black appears 
at one edge of the screen. This band represents the first band of the greyscale pattern, which should be 
100% black.
4. With the same color still active, adjust its corresponding Input Drive slide bar just until a single band of 
color appears at the opposite edge of the screen. This band represents the last band of the greyscale pattern, 
which should be 100% white (or the current color, if a certain color is enabled). 
5. Check the black band and adjust the black level slide bar if necessary. 
NOTE: Adjusting the black levels 
affects the gain. Only adjust when necessary.
6. Repeat Steps 3-5 with the two remaining primary colors. When each primary color shows one optimized 
black band and white (or colored) band, the input levels for this source are correctly set. Upon exiting the 
Input Levels menu, the Peak Detector check box will clear.

Section 3: Operation
•COLOR ENABLE 
Select which color or colors you want to see in the display, useful while working with color temperature white 
levels or input levels. 
NOTES: 1) Input levels apply for the current source only, but for any color temperature 
used. 
2) If color temperature is set up based on the internal test patterns, you can set up input levels for a given 
source so that it matches the color temperature of the internal test patterns.
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 SETTINGS - Submenu
The system offers two types of gamma correction. Gamma correction can be applied to a specific source to 
correct for luma encoding. This is a channel setting and reapplied every time the same signal is detected. This 
is the Gamma control. On the other hand the system also provides a global Gamma Correction control. The 
global control offers an offset applied to all channels. This offset is used to compensate for changes in ambient 
conditions such as ambient light in the room and projected material. 
• GAMMA CORRECTION
Applies a global offset to all gamma settings for each channel. It affects the shape of the curve by performing a 
linear transform toward a gamma curve of 1.0 while the control is increasing and likewise a linear transform 
toward a gamma of 3.0 as the control is decreasing. The control should only be adjusted to compensate for 
ambient conditions. To correct a particular source only, use the Gamma control. 
•GAMMA
Select the base gamma table for a given source. Select from one of the standard tables, a custom gamma 
function, or select an arbitrary gamma table that has been downloaded to the projector. 
NOTE: A separate PC 
utility is needed to do this.

The 2.22 curve is a power curve typically used to encode graphics 
and video sources, see Figure 3-29 Gamma Curve. The standard 
curve (auto setup default) is a modified 2.22 curve with a small 
linear section in the black that enhances the detail in darker areas 
of the projected content. Typically standard or 2.22 is used for all 
sources. Alternatively, if neither default is ideal, apply a simple 
gamma curve by defining a custom power function and slope. 
Select Gamma Function from the drop down list to enable the 
Gamma Function and Gamma Slope controls. For more complex 
non-standard gamma curves, a user-defined curve created 
externally and downloaded to the projector can be used (requires 
separate PC-based Arbitrary Gamma software application to create the table and the Web UI to download it). 
NOTE: If any of these special user curves have been installed, their names will appear in the Gamma Table 
pull-down list.
•GAMMA FUNCTION
Defines the base gamma power curve used when the base gamma table value is set to Gamma Function. This 
value, combined with gamma slope setting determines the base gamma table to be used as the custom base 
table. The curve is generally a power curve with a small linear segment at the bottom defined by the slope.
•GAMMA SLOPE 
This control defines a slope to be used for the base custom gamma table for a small section at the bottom of the 
curve. This slope can be used to bring in or out the low level blacks in the image. This slope combined with the 
gamma function, define the custom gamma table.
 DETAIL SETTINGS - Submenu
Adjusts the sharpness of the image. Setting detail above the halfway point can introduce ‘noise’ in the image. 
Lower settings can improve a noisy signal.
• DETAIL 
Adjust the sharpness of the image. Setting detail above the halfway-point can introduce noise in the image. 
Lower settings can improve a noisy signal. This command does not take effect unless the minimum change 
required in the Detail Threshold control is reached.
• TEXTURE ENHANCEMENT 
Applies texture detail enhancement based on adaptive horizontal, vertical, and diagonal large edge and small 
edge enhancement processes.
•DETAIL THRESHOLD
Selects a filter sensitivity to noise. A higher value may improve noisy sources especially for higher settings of 
detail.
•DETAIL OVERSHOOT 
Minimizes ringing on the enhanced edges detail and texture effects.
•SPLIT SCREEN 
Allows a snap shot of the main image to be presented on the right side of the screen to allow 
evaluation of advanced image processing features. All resizing controls are honoured on both images; 
however, image processing controls only happen on the left side image. Changing inputs, channels or 
test patterns will disable this control. 
NOTE: PIP and Tiling operation must be disabled prior to enabling 
this control.

NOISE REDUCTION SETTINGS - Submenu
• NOISE REDUCTION
Selects a filter sensitivity to noise. A higher value may improve noisy sources, but it will soften the image.
• BLOCK ARTIFACT REDUCTION 
Locates and reduces block edges produced by discrete cosine transform (DCT) based compression processing.
• MOSQUITO NOISE REDUCTION 
Reduces mosquito artifacts around sharp edges in DCT based compression by dynamically adapting to image 
content.
• SPLIT SCREEN
Provides a snap shot of the main image to be presented on the right side of your screen to allow evaluation of 
advanced image processing features. All resizing controls and input card features; such as color/tint etc, are 
honoured on both images. However; image processing controls such as the detail-texture, noise reduction and 
adaptive contrast features, only occur to the left side image. Changing inputs, channels or test patterns will 
disable this control. 
NOTE: PIP operation must be disabled prior to enabling this control.
• FULL SCREEN EYE-MOTION FILTER
Select this control to apply the Eye-Motion Filter to the entire screen, rather than applying just to the edge 
blending.
• EYE-MOTION FILTER 
Allows you to adjust this filter to reduce saccadic eye-motion artifacts, sometimes noticeable in edge blending 
regions. Too much filtering may result in loss of detail. 
NOTE: For best results, adjust this setting while 
positioned at the nominal screen viewing distance. 
COLOR SETTINGS - Submenu
• SELECT COLOR ADJUSTMENT
Select the output color adjustment most suited to this input signal. The options include the following:
Max Drives - All color adjustments are turned off allowing the projector to run at maximum brightness. 
Color Temperature - Allows you to specify a color temperature between 3200 and 9300 based on the setting 
of the color temperature slidebar.
Expressed in degrees Kelvin [3200K, 5400K, etc.]. Lower numbers appear reddish white and higher numbers 
appear bluish. 
Standard settings are:
9300K, is close to the white of many computer monitors
6500K, is the standard for color video, in both standard and high definition forms
5400K, is a standard for graphics and black and white video
3200K, is useful if the projected image is to be filmed or shot as part of a studio set illuminated with 
incandescent lights
For all color temperatures the color primaries; red, green, and blue are unchanged and reflect the native colors 
of the projector.
SD Video and HD Video - Sets the output color to a specific standard value. Adjusts the colors; red, green, 
blue, and white.
User# - Select 1 of 4 user defined sets of color adjustments; defined in the Configuration 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 (slidebar default of 0), the maximum amount of light passes through for 
maximum brightness in your images. Increase the slidebar setting to reduce the aperture diameter and 
maximize contrast ratio instead. Performance of aperture depends on the lens in use.
NOTE: Optical Aperture (when present) also appears in the Lamp menu. 
Aperture Manual Adjustment
A variable position manual aperture is present on the 1.2:1 and 1.1:1 lens. It may be used together with the 
internal electronic aperture to increase the contrast ratio; noting a slight decrease in brightness when it is used. 
It is recommended for highest brightness operation, under normal conditions, the manual aperture is to be left 
open. See Figure 3-30 Aperture Manual Adjustment below for aperture Open/Close, and Lock and Unlock dial 
positions. NOTE: The lock/unlock dial position allows you to open the aperture at a desired position and lock 
it in place.

3.8.1 LANGUAGE
Select the available language to use in the projector menus. The change will take effect immediately.
3.8.2 OUTPUT OPTIONS CARD - Submenu
• SCREEN IMAGE ORIENTATION 
Select the on screen image orientation from Front, Rear, Front Inverted, and Rear Inverted.
•FRAME LOCKING 
Select how the projector controls the output frame timing based on the input signal. When set to Framelock, 
output image frames are locked to the input if possible. When Locked, the output is always locked to the 
primary input, never the PIP/Secondary image. Free Run sets the output to close to 60Hz for all sources. 
NOTE: When switching to a new input with framelocking enabled, the image will appear black for a short 
duration while the system locks onto the new input.
•SET FRAME DELAY 
This control delays the output signal timing relative to the input signal timing by a fraction of a frame, and up 
to several frames. The minimum latency can vary based on the amount of scaling applied to the image. When 
using keystone or warping, an additional latency is required, depending on the amount of warp. The control is 
only available when the input signal is frame locked. In free run mode, or in cases where the signal cannot be 
frame locked, the minimum latency defined by the scaling and keystone/warp is applied to the signal.
•ACTUAL FRAME DELAY 
Dynamically calculated by the software as the achievable range being smaller than the set range.  The image 
parameters include, image shift, scaling, warp/keystone applied and format.  The menu displays both the user 
selected value and the actual frame delay value.  When setting up tiling of projectors, all projectors in the tile 
should be set to the worst case, which is the projector with the highest minimum for the setup.
•FREE RUN FREQUENCY 
This control sets the output video vertical frequency.
•FADE TO BLACK TIME 
This control sets the amount of time (in seconds) that it takes to fade the image to/from black. 
NOTE: The OSD 
only allows the fade time to be set. To initiate a Fade to Black, the Christie Serial command should be used.
•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/PIP Loop will loop the Main & PIP video to the outputs, 
regardless from which card these signals originate. The Main video signal is looped to Output1 and the PIP 
video signal is looped to Output2. Selecting Disable will shut off the HDMI outputs completely.
3.8.3 LENS SETTINGS - Submenu
•INTELLIGENT LENS SYSTEM 
Check this box to enable the Intelligent Lens System (ILS). When enabled, the lens position (horizontal, 
vertical, focus, and zoom offsets) are stored per channel. If you change channels, the lens position will change 
as the new signal is being displayed.When ILS is not enabled, the lens is controlled independently of channels 
or input signals.

• MANUAL ZOOM/FOCUS
When this control is selected, the holding current is removed from the zoomand focus motors so that they can 
be changed manually.
 NOTE: Zoom and Focus should not be adjusted manually when this control is not 
selected, as this will result in damage to the motors.
•CALIBRATE 
The lens calibration procedure is needed each time a new lens is installed in order for the ILS feature to 
perform reliably. This procedure calibrates; horizontal, vertical, focus, and zoom offset movements.
•LOCK ALL LENS MOTORS 
Select this check box to prevent all lens motors from moving. It will disable the Zoom, Focus, Horizontal and 
Vertical Position settings, effectively locking out any changes and overriding all other lens features. This 
feature is particularly useful to prevent accidental lens position changes in multi-projector installations.
•CALIBRATE ON NEW LENS  
Check this box to prompt for a lens calibration each time a lens is inserted. The user will always be prompted 
before starting the calibration.
•CALIBRATE ON STARTUP 
Check this box to initiate a ‘Lens Reset’ procedure on every power-up. This is useful if the lens is subject to 
manual movement between power sessions.
•HOME POSITION 
Return the lens to the horizontal and vertical home position. Focus and zoom are unaffected.
•CALIBRATION STATUS 
Displays the current lens calibration status.
3.8.4 POWER MANAGEMENT - Submenu
•LCD BACKLIGHT 
The backlight for the LCD has 3 states. Always On, Always Off, or Timer. The backlight will turn on again 
when any key on the LCD is pressed or if an alarm is raised.
•LCD BACKLIGHT TIMER 
Set how long the LCD backlight stays on (in seconds) when in timer mode. 
•LCD BACKLIGHT LEVEL 
Sets the LCD backlight brightness level. Maximum 25/Minimum 0.
•AUTO POWER UP 
If there is an AC power interruption, while Auto Power Up is enabled, the projector will resume operation in 
the same state as it left off. If the lamps are on and an image showing when AC power is lost, the projector will 
automatically power back up with the lamps on and an image will show when AC is restored. 
•AUTO SHUTDOWN ENABLE 
When Auto Shutdown Mode has been selected, and no projector activity has been seen for the activation time-
out period, the projector will enter a power saving mode in which the lamps will dim and the shutter will close. 
If this condition persists for an additional time-out period, the projector will automatically go to Standby mode. 
The presence of any activity within this combined interval will cancel Auto Shutdown and return the projector 
to normal operation.

Section 3: Operation
•TURN OFF IMAGE AFTER (min) 
This sets the activation interval (in minutes) for Auto Shutdown. If all activity (input signals, web or serial port 
activity, key presses) is lost for this length of time, and Auto Shutdown is enabled, an Auto Shutdown cycle 
will begin.
•ENTER STANDBY AFTER (min) 
This sets the interval (in minutes) between starting Auto Shutdown and entering Standby mode. Once Auto 
Shutdown has been entered, and all activity continues to be absent for this interval, the projector will 
automatically enter power Standby mode.
•OVER-TEMP FAN ASSIST 
When enabled, this option will cause all fans to come on at full speed if any enabled thermal sensor has an 
over-temperature fault. This may help to prevent an emergency shutdown if the extra cooling can bring the 
temperature within limits before the shutdown occurs. The fan assist will cause increased noise levels due to 
the simultaneous full speed operation of all the fans. Normal operation will resume when all over-temperature 
conditions are removed or fan assist is turned off.
