 User’s Manual     3-15. 
NOTE: The C han nel key may display a channel 
list or not, depending on what you have 
defined for “Display Channel List” (see 
Menu Preferences later in this section). 
In order to access channels by using 
C han nel on 
the keypad, you must first create the channels. 
See below. 
To use a new source with the projector, a new 
channel must be added to projector memory 
so that the projector will respond properly to an input signal from that source in the 
future. A new channel can be created automatically, as described here, or it can be 
copied from an existing channel and then edited as necessary (see Copying or 
Deleting Channels later in this section). 
When you select a direct input (
Input  1, Inp ut  2, Input  3, Input  4, Input  5 or Input  6), 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 01-50. 
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 two 
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. 
If the incoming signal does match an existing channel, the image will be set up and 
displayed as usual according to the parameters currently defined for that channel.  
USING A CHANNEL: You can normally select a channel at any time by pressing C han nel 
(see right). If you want to prevent a channel from appearing in this list, you must edit 
the channel as described in Channel Edit later in this section. Such a channel can still 
be selected by entering its number as shown at right. 
NOTES: 1) The current 
channel is highlighted upon 
entering the channel list, 
or, if this channel is not 
displayed here, 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.

All available channels are listed in the Channel Setup menu, which describes how 
each channel can be accessed and which serves as the gateway for editing, copying 
and deleting channels. 
From the presentation 
level press 
Menu to display 
the Main menu. To 
display the Channel Setup 
menu, press
 
3, or 
move the highlight to the 
Channel Setup option and 
press
 
. The Channel 
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 
are connected on the input panel. The far left column lists 
channel numbers currently defined. The values in the far 
right columns indicate horizontal and vertical 
frequencies—if someone 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, 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 C han nel 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.

FUNCTIONS WITHIN THE CHANNEL SETUP MENU —To copy, delete or edit a channel, 
highlight the desired channel in the Channel Setup menu and do one of two things: 
• Press 
Func if you want to copy the selected channel or delete this or 
other channels. See Copying or Deleting a Channel below. 
• Press 
 if you want to edit channel setups (i.e., non-image related 
parameters) for the selected channel. See Editing a Channel Setup, 
below. 
TO COPY A CHANNEL, highlight the desired channel in the Channel Setup menu, then 
press 
Func 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 01-50. If you change your 
mind and do not want to copy the current channel, press 
Ex i t 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 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 confirmation box appears to make sure that you really 
want to delete. Select “Cancel” (default) if you don’t want to delete after all. 
The basic setups that describe how and where a channel can be accessed are listed in 
the Channel Setup menu. These channel setups can be edited at any time in the 
Channel Edit submenu. 
From the presentation level press 
Menu to display the main menu. To display the 
Channel Setup menu, press
3, or move the highlight to the Channel Setup option 
and press
 
. The Channel Setup menu will appear.

press
. The Channel Edit menu will appear similar to the sample shown in Figure 
3.12. 
 
Figure 3.12. Channel Edit Menu (SAMPLE) 
If desired, review and/or edit the following channel setups in the Channel Edit menu: 
• 
CHANNEL NAME: An alpha-numeric label can be defined and/or changed here. 
Channel names can be up to 12 characters in length. 
• 
CHANNEL NUMBER: A 2-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 50 channels. 
• 
INPUT: 1-8, corresponding to where on the projector’s input panel the source is 
connected. 
• 
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 han nel key is pressed. If unchecked, the channel must be 
accessed via 
C han nel 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.   Editin

• 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 
C han nel 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 disabled. 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. 
 
The most commonly used options for image adjustments are accessed through two 
menus: Size and Position (
1Menu)and Image Settings (2Menu), 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. 
Ex i 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 
23Menu 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 
Contra st to 
access the “contrast” slidebar immediately. Press 
Ex i 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) 
For a good and efficient first step in perfecting the image, press
 
Auto. This initiates an 
automated process in which the projector quickly optimizes critical display parameters 
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 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 
Ex i t or
 Menu). 
Resize Presets 
NOTE: The same resize presets are available to all “DW” widescreen models. 
Please note however, the graphics used to describe each preset in this section are of 
the SXGA+ models only.  
Select 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 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 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.

							Section 3: Operation 
 
  
 User’s Manual     3-21. 
 
• Select
 “NO RESIZING” to display 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. 
 
• Select “FULL SIZE” to use 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.  
• 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 black 
bars at top and bottom.  
 
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 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 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. 
 
  
						

							Section 3: Operation 
3-24   
  User’s Manual      
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.
