3. Use the following option to select the source of the image for the main Secondary image. Menu > 
Secondary Input & Switching > Main Input and Menu > Secondary Image Settings > Secondary 
Input Levels
The image will be displayed according to the following:
If it is the first time you have used the source/input (or if you used the input but did not define a channel by 
adjusting anything), the projector will recognize the new input signal based on its frequencies and polarities, 
automatically displaying an image according to default settings for that signal. 
In general, the image from the new source will be as large as possible without losing its aspect ratio. This and 
other default image settings depend on the incoming source.
If you used the source once before and changed a display parameter, such as contrast, V-Position, etc., then a 
channel was automatically created and still exists in projector memory (see CHANNEL below). Using one of 
the input or slot keys will automatically recall this channel—and all its setup parameters—and update the 
display accordingly.
Creating a New Channel
To use a new source with the projector, a new channel must be created so that the projector will respond to an 
input signal from that source. A new channel can be created automatically, or it can be copied from an existing 
channel and then edited as necessary, refer to Figure 3-14 Copy A Channel and Figure 3-15 Delete a Channel.
When you select a direct input (S
LOT 1, SLOT 2, SLOT 3, or SLOT 4), any existing channels in the projector are 
searched for matching input and signal parameters – this only occurs if Auto Source is enabled on these 
channels. If no match to the incoming input signal is found in currently defined channels, a new channel is 
temporarily created based on factory-defined defaults for this type of signal. The channel number assigned is 
the lowest available number from 01-99. 
NOTES: 1) An automatic channel will be discarded unless one or 
more of its parameters are changed and will not appear in the channel list (see below). 
2) If 2 channels have 
the same distinguishing source characteristics except for the reversal of sync connectors (i.e., H-sync and V-
sync, are switched), they are still defined as distinct channels. 
3) You cannot define a new channel without an 
incoming signal.
USING A CHANNEL: You can normally select a channel at any time by pressing C
HANNEL (see below). If 
you want to hide a channel from appearing in this list, you must edit the channel refer to Figure 3-11 Channel 
List. Such a channel can still be selected by entering its number as shown below.
NOTES: 1) The current channel is highlighted 
in the channel list, or, if the current channel is 
hidden, the first channel in the list is 
highlighted. 
2) Channels created automatically 
do not appear in the channel list unless a 
parameter for the channel has been changed.

Section 3: Operation
3.4 Channel Setup Menu
All available channels are listed in the Channel Setup menu, which describes how each channel can be 
accessed and provides access for editing, copying and deleting channels.
Press M
ENU from the presentation level to display the Main menu. To display the Channel Setup menu, press 
3, or move the highlight to the Channel Setup option and press E
NTER. The Channel Setup menu will appear 
(see sample below).
The channel setup icons list all defined channels. The far left column lists channel numbers defined. The values 
in the far right columns indicate horizontal and vertical frequencies or if there is a defined name for a channel, 
it appears here. The H & V frequencies will not appear if a name has been defined for the channel; instead the 
name is only seen. The H & V frequencies are inserted as, the name when the channel is first created. The 
vertical frequency is displayed with the sync polarity. The remaining columns pertain to each signal type; such 
as, input number, slot location, a variety of icons indicating access to each channel, and an abbreviated 
description of each signal type. 
NOTE: Use UP ARROW KEY and DOWN ARROW KEY to see the remaining 
channels not visible in the initial display of channels.
SIGNAL TYPE — The channel list or the Channel Setup menu, identifies signal types abbreviations as 
defined below in Table 3.2 - Abbreviations for Signal Type. Composite Sync on the H/C input or the V input 
(4-wire). These abbreviations are preceded by either an ‘i’ (interlaced signals) or ‘p’ (progressive signal).

to the Select Channel Operation submenu. Select “Copy” and press E
NTER—a new channel will be created. It 
is identical to original, which still remains, but it is identified with the next available number from 01-99. If 
you change your mind and do not want to copy the current channel, press E
XIT to cancel and return to the 
previous menu. Copying channels is a quick method for creating numerous channels, each of which can then 
be edited and adjusted for a variety of presentations in the future.
TO DELETE A CHANNEL, highlight the desired channel in the Channel Setup menu, then press E
NTER to 
activate the Select Channel Operation submenu. Select Delete and press E
NTER—a window will appear to 
confirm the deletion of this channel.
TO DELETE MULTIPLE CHANNELS highlight any channel in the Channel Setup menu and press E
NTER 
to go to the Select Channel Operation submenu. Select Delete Unlocked Only and press E
NTER to delete all 
unlocked channels. Select Delete All Channels to delete all channels, even those that are locked. In either 
case, the current channel will remain but will be redefined from projector defaults. 
NOTE: For any deletion, a 
window will appear to confirm the deletion of the desired channel. Select C
ANCEL (default) if you don’t want to 
delete after all.
Press M
ENU from the presentation level to display the Main menu. To display the Channel Setup menu, press

Section 3: Operation
To edit parameters shown in the Channel Setup menu, select the relevant channel and press ENTER. The 
Channel Edit menu will appear similar to the sample shown below.
If desired, review and/or edit the following channel setups in the Channel Edit menu:
•NAME 
An alphanumeric label can be defined and/or changed here. Channel names can be up to 12 characters in 
length. The default name is the horizontal and vertical sync frequencies.
• CHANNEL
 A two-digit channel number can be changed here. 
NOTES: 1) If you enter a channel number that already 
exists, a dialog message appears indicating that this number is already in use–assign a different channel 
number.
 2) You can define up to 99 channels.
•SLOT 
1-4, corresponding to which slot in the projector’s input panel the source is connected:
•INPUT 
1-6, corresponding to which input on the selected slot the source is connected to.
•IN MENU 
If checked (default, except for automatically defined channels with unchanged parameters), this defined 
channel will then appear in the list available when C
HANNEL key is pressed. If unchecked, the channel must 
be accessed via C
HANNEL on the keypad or via the Auto Source function. NOTE: On-screen display of the 
channel list is an option that must be set in the Menu Preferences menu.
•AUTO SELECT 
If checked, (default), the projector can automatically locate this channel when an incoming input signal 
matches. If not checked, the projector can locate the selected channel only when it is directly selected via 
C
HANNEL on the keypad—and a change in input signal will not result in a channel change. CHANNEL EDIT — STEP 2

•LOCKED 
If checked, all of the image settings for this channel are locked. If unchecked (default), all available image 
settings can be adjusted as desired. You cannot use Auto Setup with a locked channel.
•PREVIOUS CHANNEL 
Select this option to see or change Channel Edit settings for the previous channel in the Channel Setup list.
•NEXT CHANNEL 
Select this option to see or change Channel Edit settings for the next channel in the Channel Setup list.
3.5 Adjusting the Image
The most commonly used options for image adjustments are accessed through two menus: Size and Position 
(M
ENU 1) and Image Settings (MENU 2), both of which appear in the Main menu. From either of these two 
menus, you can change settings affecting the image from the current channel by working with the appropriate 
slide bars, check boxes and pull-down lists. E
XIT will return to the previous menu (or to the presentation, if 
from the Main menu) and accept any changes you may have entered. Settings are saved with the current 
channel.
From your presentation, you can access any of the individual options in these menus by pressing M
ENU 
followed by the appropriate two-digit number representing their location in the menu system. For example, 
press M
ENU 24 to quickly access the “Color Space” option in the Image Settings menu.
NOTES: 1) For certain options, preference may be to use a “direct key” from presentation level to go directly 
to a particular option without traveling through the menu system (available for certain display parameters 
only). For example, press C
ONTRAST to access the “contrast” slide bar immediately. Press EXIT to return to 
your presentation. 
2) To hide “direct” slide bars, disable the Display Slide bars check box in the Menu 
Preferences menu. 
3) To hide the entire menu system from view, turn off the on-screen display by pressing 
OSD then the D
OWN ARROW KEY.
For a good and efficient first step in perfecting the image, press the auto setup button, A
UTO. This optimizes 
critical display parameters such as size, position, pixel tracking, etc., based on the type of incoming source. An 
Auto Setup can save considerable setup time, and you can still adjust the image as described below. 
The best auto setup will be obtained under the following conditions:
• Input levels, it is best to have an image with saturated (very Bright) colors.
• Phase, high contrast edges are needed.
To determine active window size:
• Video images should have whites and blacks in the image
• Wide range video images should have content (including white) that extends to all edges of the image.
When AUTO is pressed, the auto setup process shall begin. In some cases for analog video a menu may appear 
that presents multiple choices that allows the user to select the format that best suits their source.  This 
selection helps the auto setup get the correct settings for the tracking and phase controls for analog sources that 
contain the same number of active lines, but have a different aspect ratios. 
• All digital and decoder option cards, will not present an additional auto setup menu since digital hardware 
provides enough information to perform the correct auto setup.
• Analog PC graphics sources (4/5-wire sync) present a list of formats based on the current active lines 
detected in the video. 
						

							3-18Mirage M Series User Manual020-100575-02  Rev. 1   (11-2010)
Section 3: Operation
• Analog Video Sources (3 wire sync on green) always have the options Default and Advanced.   Video 
sources use a look up table to determine their format based on video standards.  The Advanced auto setup 
selection measures the start pixel and start line whereas Default uses the table values as is.
3.6 Size and Position Menu
Increase or decrease the size of your image, change its proportion (aspect ratio), move the image to a specific 
area of the screen, and refine other related parameters. Use Size and Position controls to match the image 
precisely to the screen used at the site.
Resize Presets will display an image in its native 
resolution (no resizing) or will resize the image 
by maximizing either the height, width or both 
height and width, or will resize to the maximum 
size possible while keeping the original aspect 
ratio. 
Size, Position and Blanking parameters will 
automatically adjust accordingly or, if Blanking 
is set first, which defines an Active Input Area; 
Resize Preset scaling will occur in this region of 
interest only. Resizing options are explained 
below.
WHAT IS THE RESIZING DEFAULT? By default when displaying a new source, your image will utilize as 
much of the projector’s display area as possible for the type of incoming source data, but with minimal or no 
changes to aspect ratio. See Select “Default” below.
The “Custom” re-size descriptor automatically appears in the Size and Position menu when any of the values 
for Size, Vertical Stretch, H-Position, V-Position or Blanking do not correspond to those for a preset. This 
option is not offered in the Resize Presets pull-down list.
• Select DEFAULT for most sources (factory default). The image will be centered and displayed as large as 
possible depending on the type of source.
FIGURE 3-18 RESIZING DEFAULT
•NO RESIZING displays the image in its native resolution, which may or may not match the projector’s 
resolution. For example, for a source with a native resolution of 800 x 600, “No Resizing” in an SXGA+ 
projector will use the central 800 x 600 pixels and have a black border—the black border areas are unused 
areas, see below.

Mirage M Series User Manual3-19020-100575-02  Rev. 1  (11-2010)
• FULL SIZE uses all pixels for displaying the image, 
regardless of source or original aspect ratio. Incoming 
source material having a different aspect ratio than 
the projector will be stretched for display. 
•FULL WIDTH fills the projector’s display from left-to-
right without changing the original aspect ratio of the 
image. Depending on the source, data at the top and 
bottom may be discarded (cropped), or the display may 
have black borders at the top and bottom (called 
“letterboxed”). 
•FULL HEIGHT fills the display from top-to-bottom. Depending on the source, this may create borders.

Section 3: Operation
•ANAMORPHIC displays an anamorphic image in its native 16:9 aspect ratio. 
The image will fill the screen from side-to-side and be centered between black 
bars at top and bottom. 
SIZE
Controls both the image width and height in tandem, maintaining the current 
aspect ratio of the displayed signal data. 
VERTICAL STRETCH
Adjusts the height of the image while keeping the width constant. Use “Vertical Stretch” to change the aspect 
ratio of the display. 
PIXEL TRACK
Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. 
Proper pixel tracking ensures that the image quality is consistent across the screen, the aspect ratio is 
maintained, and that the pixel phase can be optimized (described below). Tracking determines the frequency of 
the pixel-sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a 
particular source are sampled. 
NOTE: By default, the projector samples at the correct frequency for most sources. 
For best results, use a test pattern such as a smooth grey consisting of a clear pattern of black and white 
pixels, or a similar “half on, half off” graphic image, such as the Windows 2000 shutdown screen. Adjust the 
slide bar until the vertical stripes broaden to the point where one large stripe fills the image. If the image still 
exhibits some shimmer or noise, adjust Pixel Phase (below).
PIXEL PHASE
NOTE: Adjust “Pixel Phase” after “Pixel Tracking”.
Adjust pixel phase when the image (usually from an RGB source) still shows shimmer or “noise” after pixel 
tracking is optimized. Pixel phase adjusts the phase of the pixel-sampling clock relative to the incoming signal.
Adjust the slide bar until the image stabilizes and each pixel is clearly defined. You may notice that you can 
stabilize the image at more than one point—i.e., you may find that the image appearance at “11” is identical to 
the image appearance at “38”, thus you can use either setting.
If some shimmer from a video or HDTV source persists, use the “Filter” control to remove high-frequency 
noise from the signal.
H-POSITION
Moves the image right or left within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in relation to the total 
number of pixels available horizontally. This varies widely according to the signal—watch the image while 
adjusting.
V-POSITION
Moves the image up or down within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in relation to the total 
number of pixels available vertically. This varies widely according to the signal—watch the image while 
adjusting.

KEEP ASPECT ON AUTO SETUP
Ensures that auto setup for any source will maintain the input aspect ratio when the default size is calculated. If 
disabled and the source is not a special case video source where a default stretch is defined, the source is scaled 
to fit the platform.
BLANKING - S
UBMENU
This submenu consists of the following options:
•ACTIVE INPUT WINDOW 
This read-only value indicates the current size 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. To specify a specific active input window size by adjust 
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.
BLANKING (TOP, BOTTOM, LEFT, and RIGHT) 
Crop the image so that unwanted edges are removed from the 
display (changed to black). Blanking defines the size of the 
Active Input Window, or area of interest. Range of adjustment 
depends on the source resolution and other factors. 
NOTE: Blanking a PIP image resembles zoom. For 
example, left Blanking zooms the right side of the PIP 
image; Right Blanking zooms the left side. There are no 
black bars.  
NOTE: PIP function is disabled in 3D mode.
3.7 Image Settings Menu
Use the Image Settings menu to alter your main 
image without affecting its size or position. Changes 
made are applied immediately and are saved when 
you exit the menu (press E
XIT or MENU). Options 
not available for the projector model or source are 
disabled and appear dim (grey).
CONTRAST
“Contrast” increases or decreases the perceived difference between light and dark areas of your image (0-100). 
For best results, keep close to 50. 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. 
NOTE: If the environment 
lighting changes, an adjustment of Gamma is recommended (see below).

Section 3: Operation
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. Conversely, high brightness changes black to 
dark grey, causing washed-out images. 
COLOR SPACE
Determines how the color components of an analog input signal are decoded for accurate color in the display. 
Useful only for analog signals and certain digital sources. Although color space for these analog signals is 
automatically determined by the projector. You may wish to override this and manually set a specific color 
space. 
NOTE: For some signals, the color space function is entirely automatic and the pull-down list is 
disabled.
The current color space appears in the Image Settings menu. Press E
NTER to select a different option:
• Select RGB unless you are using component video 
• 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 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.
VIDEO OPTIONS - S
UBMENU
This submenu is used with video sources only.
•ENABLE DECODER (AGC) 
AGC affects decoded video images only. Enter a checkmark (default) in most instances. Activate 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 most 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 is auto-detected. 
Press E
NTER 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.
