Signal Type
The Channel list or the Channel Setup menu identifies the signal type for each channel. The abbreviations 
are defined in the table below. These abbreviations are preceded by either an ‘i’ (interlaced signals) or ‘p’ 
(progressive signal).
The first 5 items in the table are analog RGB with various sync combinations, indicating Sync Source when 
editing the channel.
Copying a Channel
Highlight the desired channel in the Channel Setup menu, then press 
ENTER to go to the Channel Options 
submenu. Select Copy and press 
ENTER to create a new channel. It is identical to the 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 
EXIT 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.

3.4 Adjusting the Image
The most commonly used options for image adjustments are accessed through 2 menus: Size and Position 
(
MENU 1) and Image Settings (MENU 2), both of which appear in the Main menu. You can change settings 
affecting the image from the current channel by working with the appropriate slide bars, check boxes and drop-
down lists from either of these 2 menus. 
EXIT returns to the previous menu (or to the presentation, if from the 
Main menu) and accepts 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 
MENU followed by 
the appropriate number keys representing their location in the menu system. For example, press 
MENU, 2, 7,1 
to quickly access the “Gamma” option in the Image Settings menu.
NOTES: 1) Some frequently used display functions have dedicated keys on the IR remote. For example, press 
CONTRAST to access the contrast slide bar. Press EXIT to return to your presentation. 2) To  h i d e  “ d i r e c t ”  
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 
DOWN Arrow Key.

Section 3: Operation
3.4.1 Automatic Image Setup
Auto setup is a good first step in setting up the image. Press AUTO on the remote. 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.
3.4.2 Size and Position Menu
Increase or decrease the size of your image, change 
its proportion (aspect ratio), move the image to a 
specificarea 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. See 3.2.4 Using Slidebars and Other Controls 
if you need help using any of the options and 
controls. Changes made in the Size and Position 
menu are applied immediately and are saved when 
you exit the menu (press 
EXIT or MENU).
Resize Presets 
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 to define an Active Input Area; Resize 
Preset scaling will occur in this region of interest only. 
•Custom re-size option does not initially appear in the Resize Presets drop down list.The Resize Presets 
value changes to Custom automatically when any of the values for Size, Vertical Stretch, H-Position, V-
Position or Blanking do not correspond to those for a preset option.  
						

							Section 3: Operation
Mirage WU-L User Manual3-17020-100774-01 Rev. 2 (4-2012)
•Select Default for most sources (factory default). The image will be centered and displayed as large as 
possible depending on the type of source.
By default when displaying a new source, your image will use as much of the projector display area as 
possible for the type of incoming source data, but with minimal or no changes to aspect ratio.
•No Resizing displays the image in its native resolution, which may or may not match the projector 
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 as shown below.
•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 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 Width 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, maintaining the current aspect ratio of 
the displayed signal data. 
Ve r t i cal 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 in Pixel Phase on page 3-18). 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 gray 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 as described in Pixel Phase on page 3-18.
Pixel Phase
Adjust “Pixel Phase” after “Pixel Track”. 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 slidebar until the image stabilizes and each pixel is 
clearly defined. You may notice that you can stabilize the image at more than one point. For example, you may 
find that the image appearance at “11” is identical to the image appearance at “38”, 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
Move the image right or left within the area of available pixels. The value shown represents the approximate 
center of the image in relation to the total number of horizontal pixels. It varies widely according to the signal; 
watch the image while adjusting.
V- P o s i t i o n
Move the image up or down within the area of available pixels. The value shown represents the approximate 
center of the image in relation to the total number of vertical pixels. It varies widely according to the signal; 
watch the image while adjusting.
Keep Aspect on Auto Setup
Maintains the input aspect ratio when calculating the default size in auto setup. If disabled the source is scaled 
to fit the platform, except where the video source includes a defined default stretch.

Blanking
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. Specify the active input window size by 
adjusting one or more Blank settings (Figure 3-10). 
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. 
3.4.3 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 
EXIT or MENU). Options 
not available for the projector model or source are disabled, and appear 
dim (gray).
Image color is managed by ArrayLOC (see ArrayLOC Menu on page 3-45 and Managing Colors with 
ArrayLOC on page 3-55).
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).
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 gray, causing washed-out images. 
Reserved
This selection is reserved for future use.

Section 3: Operation
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 drop-down list is disabled.
The current color space appears in the Image Settings menu. Press 
ENTER to select a different option:
• Select RGB unless you are using component video. 
• Select YCbCr SDTV (ITU-R BT.601) with a standard definition televised signal (SDTV).
• Select YCbCr HDTV (ITU-R BT.709) 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 YCbCr (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
This submenu is used with video sources only. See Video Options Menu on page 3-20.
Input Levels
Only experienced users should use the Input Levels submenu. With 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. Use this menu to manually adjust blacks 
and whites. See Input Levels Menu on page 3-22.
Advanced Imaging Settings
Use the Advanced Image Settings submenu to make the adjustments necessary for lesser-used but more 
specialized applications on your projector. See Advanced Image Settings Menu on page 3-25.
Video Options Menu
This submenu is used with video sources only. 
• Enable Decoder AGC 
Automatic Gain Control (AGC) affects decoded video 
images only. Enter a check mark (default) to activate 
the decoder’s AGC circuit to ensure properly bright 
images. Delete the check mark 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. 
						

							Section 3: Operation
Mirage WU-L User Manual3-21020-100774-01 Rev. 2 (4-2012)
•Video Standard 
Identifies the standard used to process the video signal. For most sources, the projector automatically detects 
the incoming horizontal and vertical frequencies and sets the signal processing to the corresponding standard. 
An “A” indicates auto-selection. Press 
ENTER to select a different video standard from the list. Standards that 
have frequency characteristics that differ from those of the incoming signal are disabled. 
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.
 
NOTE: Generally, use “Auto” for all instances except: a poor quality input signal or 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 slide bar adjusts the color saturation level. 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
Adjusts the red/green color hue for true color reproduction of video and HDTV signals. For best results, 
adjust tint while displaying an external test pattern. It is recommended that tint remain at its default setting.

Section 3: Operation
•Filter
The proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. 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.
• Sampling Mode
Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB or YCbCr 4:2:2. The proper 
sampling mode is determined automatically by the projector; you can override this setting.
• Film Mode Detect
Enable or disable film motion detection. Only available for interlaced or segmented frame sources.
• 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.
• Adaptive Contrast
Dynamically expands the contrast of the output image producing vibrant images with seamless response to 
scene changes and fades. The slide bar adjusts the amount of adaptive contrast to apply, with a setting of “0” 
producing no change. 
• 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.
• RGB Quantization Range
This control defines the RGB quantization levels for digital DVI and HDMI inputs using the RGB color space. 
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). A limited CE range is 16-235 for 8-bit video sources.
Input Levels Menu
Only experienced users should use the Input 
Levels submenu. The projector automatically 
optimizes input levels for all but the most unusual 
of sources. Before starting, check that overall 
contrast and brightness settings are near 50 and 
that color temperature is properly set up on an 
internal grayscale test pattern. Good RGB or input 
levels (that is, the drives and black levels for each 
of the 3 colors, red, green and blue) ensure that 
images from analog sources other than decoded
