Advanced Size and Position — SUBMENU 
This submenu consists of the 
following options: 
ACTIVE INPUT WINDOW: This 
read-only value indicates the 
current size (i.e., area) of your 
displayed data or “region of 
interest” as defined by the 
blanking controls. By default, the 
projector automatically 
determines what portion of its full resolution to use, and pixels in the surrounding 
borders are turned off. You can also specify a specific active input window size by 
adjusting one or more “Blank” settings. For example, if you have blanked (cropped) 
100 pixels from both the left and right edges of an incoming source of 1400 x 1050, 
the remaining active input window will be reduced to 1200 x 1050. When using SD 
or HD or a decoded video source at 
INPUT 3 or INPUT 4, the default blanking of “0” 
defines an active input window of 720 x 483. 
BLANKING (TOP, BOTTOM, LEFT, and 
RIGHT): 
Crop the image as desired so that 
unwanted edges are removed from the 
display (changed to black—see Figure 
3.14). Blanking defines the size of the Active 
Input Window, or area of interest. Range of 
adjustment depends on the source resolution 
and other factors. After adjustment of 
blanking it may be necessary to perform a 
source switch.  
NOTE: Blanking a PIP image resembles 
zoom (Figure 3.15). For example, left 
Blanking zooms the right side of the PIP 
image; Right Blanking zooms the left side. 
There are no black bars.

PLUG & DISPLAY (EDID): By default, a Plug & Play 
 source outputs a signal according to the 
EDID information provided by the projector. To 
override this information and display in a different 
format (for example, if your Plug & Play [EDID] 
device does not support the projector’s resolution 
and/or frequency), select the desired Plug & Play 
 resolution from the list. 
Any daisy-chained projectors will also display 
according to the chosen Plug & Play  
format. 
EDID = Extended Display Identification Data standard. 
Use options in the Image Settings 
menu to alter your main image 
without affecting its size or 
position. Changes made to the 
Image Settings menu are applied 
immediately and are saved when 
you exit the menu (press 
Ex i t or
 Me nu). Options not available for 
the projector model or source are 
disabled and appear dim (gray). 
Contrast 
(
SHORT CUT: Press Contra st and adjust the slidebar.) 
“Contrast” increases or decreases the perceived difference between light and dark 
areas of the image (0-100). For best results, keep close to 50. If the contrast is set too 
high, the light parts of the image lose detail and clarity. If the contrast is set too low, 
the light areas will not be as bright as they could be and the overall image will be 
dim. For best results, start with a low value and increase so that whites remain bright 
but are not distorted or tinted, and that light areas do not become white (i.e., are 
“crushed”).  
NOTE: If the environment lighting changes, an adjustment of Gamma is 
recommended (see below). 
Brightness 
(
SHORT CUT: Press Br i g h t and adjust the slidebar.) 
“Brightness” increases or decreases the amount of black in the image (0-100). For 
best results, keep close to 50. Start with a high value and decrease so that dark areas 
do not become black (i.e., are “crushed”). Conversely, high brightness changes black 
to dark gray, causing washed-out images.  
NOTE: Brightness should be adjusted before contrast, as Brightness setting affects 
the contrast setting.

Gamma 
(
SHORT CUT: Press Gam m a and adjust the slidebar.) 
“Gamma” is a global setting that determines what gray shades are displayed between 
minimum input (black) and maximum input (white) for all signals. A good gamma 
setting helps to optimize blacks and 
whites while ensuring smooth transitions 
for the “in-between” values utilized in 
other colors. Thus, unlike “Brightness” 
and “Contrast” controls, the overall tone 
of your images can be lightened or 
darkened without changing the extremes, 
and all images will be more vibrant while 
still showing good detail in dark areas.  
Gamma is used to fine-tune the gamma table currently in use, ranging from 1 – 3 (2.2 
= default). If excess ambient light washes out the image and it becomes difficult or 
impossible to see details in dark areas, lower the gamma setting to compensate. This 
will improve contrast while maintaining good details for blacks. Conversely, if the 
image is washed out and unnatural, with excessive detail in black areas, increase the 
setting. In high ambient light conditions, lower gamma may produce better results 
than higher gamma. Gamma of 2.2 (default) indicates the gamma table has not been 
adjusted. For more information, refer to Advanced Image Settings submenu, Gamma 
Table. Again, good gamma improves contrast while maintaining good details for 
blacks. 
Filter 
The proper filter setting is automatically set for virtually all 
signals, and rarely needs to be changed.  It applies a low pass 
filter for noise reduction in the incoming input signal, 
particularly for HDTV or SDTV. Applied in the analog domain 
before sampling, this filtering removes high frequencies and 
thus reduces pixel phase noise (note this also reduces signal 
bandwidth). Override only if standard pixel tracking and phase adjustments do not 
adequately clear up a “noisy” video signal, or if a graphics signal appears overly 
“soft”. Both instances indicate that “Filter” may be set to the wrong option.

Detail 
“Detail” adjusts the sharpness of a video image so that edges remain clearly defined. 
It can be particularly useful if a significant “Noise Reduction” adjustment has caused 
the image to appear too soft. Adjust until the display is as sharp as desired, keeping in 
mind that because “Detail” adds some high frequencies back into the image, it can 
also re-introduce a certain degree of noise. 
Noise Reduction 
“Noise Reduction” is similar to the “Filter” control, but operates in the post-sampling 
digital domain with a more subtle effect. Higher settings are most useful for clearing 
up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind 
that reducing noise (which reduces high frequencies) may also soften the image. 
Color Space 
“Color Space” determines how the color components of an 
analog input signal are decoded for accurate color in the 
display. Selecting a color space option is useful only for analog 
signals and certain digital sources connected to 
INPUT 1, INPUT 
2, INPUT 5
 or INPUT 6. Although color space for these analog 
signals is automatically determined by the projector, in some circumstances you may 
wish to override this and manually set a specific color space. 
NOTE: For many digital signals or for signals connected to 
INPUT 3 or INPUT 4, the 
color space function is entirely automatic and the pull-down list disabled. 
The current color space appears in the Image Settings menu. Press 
 to select a 
different option: 
 Select 
RGB unless you are using component video at INPUT 1, 2, 5 or 6. 
 Select 
YPbPr (Video) with a standard definition televised signal (SDTV). 
 Select 
YPbPr (HDTV) with a high definition televised signal (HDTV). 
NOTE: When certain RGB signals are first connected, the projector may not initially 
recognize them as RGB and will incorrectly decode their color information as YPbPr 
(video). These signals can include: 
 RGB signals in NTSC, PAL, SECAM frequency ranges. 
 Scan-doubled sync-on-green. 
 Scan-quadrupled sync-on-green. 
For these signals, change the Color Space to RGB and then define a new channel for 
future use.

ENABLE DECODER AGC: Automatic Gain Control (AGC) affects decoded video 
images only. Enter a checkmark (default) in most instances—this activates the 
decoder’s AGC circuit to ensure properly bright images. Delete the checkmark if a 
decoded video image exhibits strange color artifacts such as stripes in highly 
saturated colors, indicating an incompatibility between this source and the AGC. 
VIDEO STANDARD: For all but the more unusual video standards 
available in the world, the projector automatically detects the 
incoming horizontal and vertical frequencies and sets the 
projector’s processing of this signal to the corresponding standard. 
The current video standard name appears in the Video Options 
submenu, and includes an “A” if it has been auto-detected. Press 
 to view or select a different video standard from those 
available to the projector—any that are disabled have frequency 
characteristics that differ from those of the incoming signal. 
Selecting a specific standard forces the projector to process the signal according to 
this standard. 
NOTE: Best results are obtained with defined channels. Otherwise, switching from 
one video source to another can sometimes cause slight disturbances in the display, 
indicating that the Auto function is struggling. Recover by briefly selecting a different 
video standard, then going back. 
Table 3.3. Regions and Video Standards: Summary 
StandardWhere Used (SUBJECT-TO-CHANGE)
NTSC N. America and Japan 
NTSC 4.43 A tape-only standard for partially-translated hybrid signals 
PAL Most of Europe, China, Australia, some of S. America, some of Africa 
PAL-M Brazil 
PAL-NC Argentina, Chile, other Latin American countries 
PAL 60  
SECAM France, Eastern Europe, most of Africa 
NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input 
signal or 2) a black-and-white video signal. In order to detect and display such 
signals, select the relevant standard from the list. 
INPUT VIDEO BLACK: This control 
compensates for incoming elevated black 
levels present in certain video signals, and 
ensures that blacks in the display are 
neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., 
where blacks appear dark gray). By default, the projector automatically determines the 
best setting according to the type of incoming video signal: 
 
0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL 
standards, and Japanese NTSC. 
 
7.5 IRE – Used for most NTSC video signals. 
For some types of video, you can override the setting. The control is disabled for other 
types of video (and all graphics sources). Generally, if black appears crushed when 
brightness = 50, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.

COLOR: This slidebar adjusts the color saturation level, i.e. the amount of color in a 
video image. Lower settings produce less saturated colors — for example a setting of 
“0” produces a black and white image. If the color level is too high, colors will be 
overpowering and unrealistic. 
TINT: This slidebar adjusts the red/green color hue for true color reproduction of 
video and HDTV signals connected to Input 3 or 4. For best results, adjust tint while 
displaying an external test pattern—otherwise, it is recommended that tint remain at 
its default setting. 
DECODER LUMA DELAY: This control 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. 
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 
grayscale test pattern. 3) There must be at least 2 consecutive white pixels present in 
the image for proper “Auto Input Level” function. Leave this control off after use.  
Good RGB or input 
levels—that is, the drives 
and blacklevels 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. 
However, for a very unusual source exhibiting one or more overly high blacklevels 
(typically caused by a noisy source causing blacklevel spikes), an experienced user 
may prefer to use the Input Levels menu (shown above). These adjustments, which 
together serve as a calibration process compensating for differences in sources and 
cabling, enable an experienced user to perfect the source image input levels and 
eliminate the “overshoot” and “undershoot”. Note that Input Levels are of limited use 
with digital signals, but do offer some ability to tweak poorly mastered source 
materials.

Roadster, Matrix WU, Mirage S+/HD/WU User Manual 3-33 020-100002-05 Rev. 1 (02-2010) 
NOTES: 1) Input levels apply for the current source only, but for any color 
temperature used. 2) 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 – Temporarily enter a checkmark 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 blacklevels (black) that would cause “crushing” of light and dark colors 
in the image. After entering a checkmark, wait for the six slidebar values to stabilize, 
and then delete the checkmark and exit. The Auto Input Level is automatically turned 
off upon exit from the Input levels Menu.  
BLACKLEVELS 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. 
 
Contra st= 50 (approx.) 
 
Br i g h t= 50 (approx.) 
2. Check the color temperature setup using an internal grayscale test pattern, 
making sure to obtain a neutral grayscale.  
NOTE: Not required for “Auto” adjustment. 
3. Confirm that you are using an analog source not connected to 
INPUT 3 or INPUT 
4
, as Input Levels are not applicable for digital sources or sources going through 
the decoder. A grayscale is recommended. 
4. If the blacks and/or whites appear OK, input levels do not need adjustment. 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. Continue with Step 5. 
5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all six values 
to stabilize. Alternatively, do not use “Auto”—reduce blacklevels 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 “Color Enable” option (described below). 
6. 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 blacklevel 
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 – This option (formerly known as sync tip 
clamping) can brighten the image produced from certain high-
resolution high-frequency graphic sources. For almost all 
sources, the projector automatically selects the best clamp 
location. 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. 
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. 
PEAK DETECTOR – The Peak Detector is 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 gray. When used with a smooth grayscale 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 blacklevels 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 3.16. Adjusting Input Levels Using the Peak Detector
: 
1. Display a 16 level grayscale test pattern from the desired external source, and 
enter a checkmark in the Peak Detector checkbox.  
NOTE: The “Peak Detector” will initially render the grayscale as a uniform 
gray field before adjustment or extreme crushing. 
2. Display one primary color.  
NOTE: Selecting Auto Color Enable ensures the correct color is displayed for 
each setting.  
3. For the current color, adjust its corresponding “Blacklevel” slidebar just until a 
single band of black appears at one edge of the screen. This band represents the 
first band of the grayscale pattern, which should be 100% black. Do not adjust 
too far. 
4. With the same color still active, adjust its corresponding “Input Drive” slidebar 
just until a single band of color appears at the opposite edge of the screen. This 
band represents the last band of the grayscale pattern, which should be 100% 
white (or the current color, if a certain color is enabled). Do not adjust too far. 
5. It may be advantageous to go back and check the black band—adjust the 
blacklevel slidebar if necessary.  
NOTE: Readjusting blacklevels at this point affects the gain; only readjust when 
absolutely necessary. 
6. Repeat Steps 3-5 with the other 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 checkbox will clear.

GAMMA TABLE: This control applies a default video, graphics or simple gamma table 
or “curve” to your images, controlling the intensity of midlevel colors and producing 
maximum contrast, brightness and color performance. As shown at right, the graphics 
curve is a simple power curve 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 value of 2.2 and is correct for most signal conditions. 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.

SELECT COLOR ADJUSTMENT: In “Select Color 
Adjustment”, choose an overall color palette for all images. 
The “Max Drives” factory default simply drives all 3 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 slidebar 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 slidebar 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. 
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 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.
