return to the current function menu. 
Slide bars in menus – The current value for a given 
parameter, such as size or vertical stretch, appears to the left 
of its slide bar icon (adjustment window). This number often expresses a percentage, 
or it may have units associated with it (such as pixels, degrees Kelvin, etc.), 
depending on the specific option. Press 
 to gradually adjust the setting up or 
down—both the number and the length of the bar change accordingly. Hold for 
continuous adjustment. Or press

Enter numbers directly from the keypad in order to specify numbers representing 
projectors, channels (source setups), or slots. As each digit is entered, it is displayed 
and the cursor moves on. Note that channel numbers are defined with two digits—for 
example, if you enter only a single digit (such as “7”) for a channel number, the 
channel will automatically be defined as “07”. Enter “07” to utilize this channel. 
NOTES: 1) Once you enter the first digit, this digit replaces all old digits. 2) If you 
press any non-numbered key, the number entered up to that point is accepted and 
updated as the new value. 3) Press 
Exit to cancel editing of numerical values. 
 
NOTE: See Section 2, Installation and Setup, for a full explanation of how to connect 
sources to the projector. 
The projector stores and automatically recalls up to 50 different channels (source 
setups) for a variety of inputs. This memory feature allows you to define and 
conveniently use a wide variety of customized setups rather than having to repeatedly 
re-configure the projector for different presentations. Depending on what you have 
defined, each physical source connection (i.e., input at the projector) can have several 
different channels associated with it. 
INPUT – An input is a source physically connected at the projector. Input describes the 
source signal according to which input slot it is connected.  
SWITCHING INPUTS – Press the appropriate direct key —Input 1,Input 2,Input 3,Input 4,Input 5 or 
Input 6 to quickly display from one of the six inputs connected to the projector. The 
image will be displayed according to the following: 
If it is the first time you have used the source/input (or if you used the input but did 
not define a channel by adjusting anything), the projector will recognize the new input 
signal based on its frequencies and polarities, and will automatically display an image 
according to default settings for such a signal. In general, the image from the new 
source will be as large as possible without losing its aspect ratio. This and other 
default image settings depend on the incoming source. 
If you used the source once before and changed a display parameter such as 
contrast, V-Position, etc., then a channel was automatically created and still exists in 
projector memory (see below). Using one of the 
Input keys will automatically recall 
this channel—and all its setup parameters—and update the display accordingly. 
If more than one channel exists for the input, the image will be displayed according 
to the setup parameters for the first channel with matching characteristics. 
NOTE: Inputs 7 and 8 require the Dual SD/HD-SDI module in either of the 
projector’s option slots. For their selection, see also 3.2 Using the Remote or Built-
In Keypad. 
CHANNEL - A channel is a collection of measurements, locations and settings that 
tailor the display of a signal to your specific needs. Since source types and 
applications can vary greatly, you will likely want to adjust and define a wide variety 
of parameters, such as brightness, contrast, size, etc., in order to customize and 
optimize the display from or for a particular source. For example, the display settings 
you choose for a VCR source may be very different from those you choose for a high-
resolution computer source, or one signal may simply vary from another signal used   Editin

previously through the same input location. Once you have adjusted a display 
parameter, such as pixel tracking or contrast, all current settings are collectively stored 
in the projectors memory as a unique two-digit channel, such as 
09. You can 
have numerous distinct channels available for the same input, any of which can be 
selected by using the 
Channel key on the keypad followed by the two-digit channel 
number. 
Shown at right is a sample channel list as would be available from
Channel. This is 
typically called the channel list. 
NOTE: The 
Channel 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 
Channel 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, Input 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 Channel 
(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.

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 Channel 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 
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. See Figure 3.4.

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 
Channel key is pressed. If unchecked, the channel must be accessed via Channel 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 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 
Channel 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 slide 
bars, checkboxes and pull-down lists. 
Exit 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 
(available for certain display parameters only). For example, press 
Contrast to access the 
“contrast” slide bar immediately. Press 
Exit to return to your presentation. 
3.5 Adjusting the 
Image  
						

							Section 3: Operation  
3-20 020-100001-01 Rev. 01 (04/07) 
NOTES: 1) To hide these “direct” slide bars, disable the “Display Slide bars” 
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 Slide bars 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 
Exit or
 
Menu). 
Resize Presets 
NOTE: The same resize presets are available to all HD and HD2 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.

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. 
 
• 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.
