the 2-digit number representing the switcher and slot location for the desired signal
(note there is no on-screen feedback for entering the numbers).
Regardless of which method you use to select a source/input, 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. Note that a graphic source will
resize into a full-screen image, whereas video or HDTV sources will resize only as
much as possible while maintaining their aspect ratio.
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 an
Input key 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.
CHANNEL -
A channel is a collection of measurements, locations and settings that
tailor a display 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, tint, size, etc., in order to customize and optimize the display
coming from 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 earlier
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 projector's
memory as a unique 2-digit channel, such as
. You can have numerous distinct
channels available for the same input, any of which can be selected by using the Chan
key on the keypad followed by the 2-digit
channel number.
NOTE: The Chan key may display a channel
list or not, depending on what you have
defined within the Menu Preferences menu
(see Menu Preferences later in this section).
Shown at right is a sample channel list

Chan .
In order to use channels ( Chan on the keypad),
you must first create them. 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 (press Input or Input1 , Input2 , Input3 or Input4 ), the existing
channels in the projector are searched for matching input and signal parameters. If no
match to the incoming input signal is found in the currently defined channels, a new
