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 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.
•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.CHANNEL EDIT — STEP 3

Section 3: Operation
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 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.
• 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.
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 E
XIT or MENU).FIGURE 3-17 SIZE AND POSITION

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.
WHAT IS THE RESIZING DEFAULT? 
By default when displaying a new source, your image will utilize 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. 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 3-19 RESIZING DEFAULT
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, see below.

Section 3: Operation
 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 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 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 (For analog input signals only)
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. 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 (analog input signals only)
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 “5” is identical to 
the image appearance at “25”, 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.

Section 3: Operation
KEEP ASPECT ON AUTO SETUP
Ensures that auto setup for any source will maintain the input aspect ratio when the default size is calculated. 
NTSC and PAL formats always keep aspect ratio during auto setup regardless of the Keep Aspect on Auto 
Setup control.
BLANKING - Submenu
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.

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 
M
ENU). 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).
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, which defines a new channel.
VIDEO OPTIONS - Submenu
This submenu is used with Video Decoder Card inputs (Composite and S-Video) only.
•ENABLE DECODER (AGC) 
AGC affects decoded video images only. Enter a checkmark (default) in most instances. Activate the decoder 
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.

Section 3: Operation
• VIDEO STANDARD 
The projector automatically detects the incoming horizontal and vertical frequencies and sets the projector 
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.
Table 3.2 - Regions and Video Standards: Summary
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 (analog input signals only)
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 greys appear 
black) nor excessively elevated (i.e., where blacks appear dark grey). 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, select “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.
•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.
