Setup menu will appear 
(see sample at right), 
with the active channel highlighted.  
WHAT APPEARS IN CHANNEL SETUP MENU? This menu lists all channels defined so 
far and indicates where they connect on the projector’s rear input panel. The far left 
column lists channel numbers currently defined. The 
values in the far right columns indicate horizontal and 
vertical frequencies—if a user has defined a name for this 
channel, it appears here instead. Remaining columns 
contain details pertaining to each channel setup, such as its 
switcher number (always 0 = projector), slot location (01-
08), a variety of icons indicating access to each channel, and an abbreviated 
description of each signal type. See Editing a Channel Setup for details. 
NOTE: If you have more than a handful of channels, use 
 and  to see the 
remaining channels not visible in the initial display of channels. 
SIGNAL TYPE — Either channel list, whether the Chan key list or the Channel Setup 
menu, identifies signal types in a shortened form as defined below. These descriptors 
indicate what signal information the projector uses to identify a match for a given 
channel, and are preceded by either an “i” (interlaced signals) or “p” (progressive 
signal“). See Table 3.2.

The most commonly used options for image adjustments are accessed through two 
menus: Size and Position (
Menu ) and Image Settings (Menu ), 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 
slidebars, checkboxes and pull-down lists. 
Exi t 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 
Menu followed by the appropriate two-digit number representing their 
location in the menu system. For example, press Menu 32 to quickly access the 
“Gamma” option in the Image Settings menu. 
Note that for certain options, you may prefer to use a “direct key” from presentation 
level to go directly to a particular option without traveling through the menu system 
(note: available for certain display parameters only). For example, press 
Cont to 
access the “contrast” slidebar immediately. Press 
Exi t to return to your presentation. 
NOTES: 1) To hide these “direct” slidebars, disable the” Display Slidebars” 
checkbox in the Menu Preferences menu.  2) To hide the entire menu system from 
view, turn off the on-screen display by pressing 
OSD . 
Use Auto Setup (
Auto
Setup) 
For a good and efficient first step in perfecting the image, press 
Auto
Setup. This initiates 
an automated process in which the projector quickly optimizes critical display 
parameters for unlocked channels such as size, position, pixel tracking, etc., based on 
the type of incoming source data detected. An Auto Setup can save considerable setup 
time, and you can still modify the adjustments as desired using menu options 
described below. 
In the Size and Position menu, you 
can increase or decrease the size of 
your main 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. 
Refer to “Using Slidebars and 
Other Controls” (earlier in this section) 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 
Exi t or Menu).

Resize Presets 
S elect a Resize Presets option 
to quickly display an image in 
its native resolution or to 
automatically resize an image 
to closely fill the projector’s 
native resolution of 1400 x 
1050, or to optimize the width 
or height of your display. 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 in detail 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 (1400 x 1050) as possible 
for the type of incoming source data. See Select “Default” below. 
WHEN “CUSTOM” APPEARS: 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. It is not a 
choice 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, as described 
below: 
9 A 5:4 graphic image will enlarge to fill the screen height, and be 
centered between narrow black side bars. 
9 A video image or 4:3 graphic image will enlarge to fill the screen width.  
9 An HDTV (16:9) image will fill the width and be centered between 
black bars on top and bottom. 
 
• Select
 “NO RESIZING” to display the image in its native resolution, which may be 
smaller than the projector’s 1400 x 1050 resolution. For example, for a source with 
a native resolution of 800 x 600, “No Resizing” will center a small image within a 
black border—the black border areas are unused areas. See below. 
 
 
  
						

							OPERATION

Roadster / Mirage S+ User’s Manual 
• Select “FULL SCREEN” to use all 
pixels (1400 x 1050) 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.  
• Select 
“FULL WIDTH” to fill 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”).  
• Select 
“FULL HEIGHT” 
to fill the display from 
top-to-bottom. 
Depending on the 
source, this may 
create borders.  
• Select
 “ANAMORPHIC” to display an anamorphic image 
in its native 16:9 aspect ratio. The image will fill the 
screen from side-to-side, and be centered between 
narrow black bars on top and bottom. This is used for 
DVD players that output widescreen images compressed 
into 4:3 NTSC format. 
Size 
“Size” controls both the image width and height in tandem, maintaining the current 
aspect ratio (proportion) of the displayed signal data. 
Vertical Stretch 
“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 helps ensure that the image 
quality is consistent across the screen, that aspect ratio is maintained, and that 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 good 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 slidebar 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. 
For best results, use a good 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 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—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 
This option 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 
This option 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. 
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 
 
  
						

							OPERATION

Roadster / Mirage S+ User’s Manual 
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 right). 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 3.14). For example, left 
Blanking zooms the right side of the PIP 
image; Right Blanking zooms the left side. 
There are no black bars.  
 
Figure 3.14. Blanking of a PIP Image 
 
PLUG & DISPLAY (EDID): By default, a Plug & Play 
(EDID) 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 (EDID) resolution from 
the list. 
Any daisy-chained projectors will also display 
according to the chosen Plug & Play (EDID) 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 
Exit or
 Menu). 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 contrast is set too 
high, the light parts of the image lose detail and clarity. If 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 Bright 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 Gamma 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 (2.5 
= default). If excess ambient light washes out the image and it becomes difficult or   Ima
ge Settings Menu

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 2.5 (default) indicates the gamma table has not been 
adjusted. For more information, refer to Advanced Image Settings, Gamma Table 
submenu. 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).
