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  and  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 COPY A CHANNEL, highlight the desired channel in the Channel Setup menu, then press   
to go to the Channel Copy/Delete submenu. Select “Copy” and press  —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   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.

Channel Edit menu will appear similar to the sample shown below.
FIGURE 3-15 CHANNEL EDIT
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.
• NUMBER:
 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.

•AUTO SOURCE: 
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   on the keypad—and a change in input signal will not result in a channel change.
•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.

3.4 ADJUSTING THE IMAGE
The most commonly used options for image adjustments are accessed through two menus: Size and 
Position () and Image Settings ( ), 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, checkboxes and pull-down lists.   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   
followed by the appropriate two-digit number representing their location in the menu system. For 
example, press   to quickly access the “Gamma” 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   to access the “contrast” slide bar immediately. 
Press   to return to your presentation. 2) To hide “direct” slide bars, disable the “Display Slide 
bars” checkbox in the Menu Preferences menu. 3) To hide the entire menu system from view, turn 
off the on-screen display by pressing .
For a good and efficient first step in perfecting the image, press Auto Setup . 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.

Use Auto Setup ( )
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.
3.4.1Size 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.
Refer to Using Slide bars 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   
or ).
• RESIZE PRESETS
NOTE: The same resize presets are available to all HD and SXGA+ screen models. However, the 
graphics used to describe each preset in this section are of the SXGA+ models only. 
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.

							Section 3: Operation
M-Series User Manual3-22020-100009-01 Rev.1 (07/08)
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.
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. 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 pro-
jector’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.
• “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. 
FIGURE 3-19 - NO RESIZING 
FIGURE 3-20 - FULL SIZE 
						

							M-Series User Manual3-23020-100009-01 Rev.1 (07/08)
•“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 dis-
carded (cropped), or the display may have black 
borders at the top and bottom (called “letter-
boxed”). 
•“FULL HEIGHT” fills the display from top-to-bottom. Depending on the source, this may create 
borders. 
•“ANAMORPHIC” displays an anamorphic image in its native 16:9 
aspect ratio. The image will fill the screen from side-to-side and be cen-
tered 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 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 (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.
BLANKING 
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. 
FIGURE 3-24 - BLANKING SUBMENU 
						

							M-Series User Manual3-25020-100009-01 Rev.1 (07/08)
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.

3.4.2Image 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   or  ). Options not 
available for the projector model or source 
are disabled and appear dim (gray).
•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. 
•GAMMA:
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. 
Gamma is used to fine-tune the gamma table currently in use, ranging from 1 – 3 (2.22 = 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 2.22 (default) indicates the gamma table has not been adjusted. For 
more information, refer to Advanced Image Settings submenu, Gamma Ta b l e. 
• YELLOW NOTCH FILTER (YNF):
YNF is a channel based control with an additional global control. It works on a “last request gets 
served” basis. i.e. Enable YNF in the global control, YNF will be enabled. Thereafter; switch to a 
channel which does not use YNF, the YNF filter will be removed (or disabled). Then change the global 
control, the YNF filter will do whatever is requested; last request is honored.
•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   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.
