NOTE: See 
Section 2, Installation and Setup, for a full explanation of how to
connect sources to the Vista
GRAPHX 10K.
Vista
GRAPHX 10K stores and automatically recalls up to 99 different channels 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.
,1387#0 An input simply describes a physical location for an incoming signal
connection. These connections are always either on the projector itself (one of
the four inputs at the front of the projector) or on any switcher connected to the
projector’s switcher port. 
,QSXW describes the source signal according to two
criteria only — to which switcher it is connected and to which slot it is
connected — and is represented by a 2-digit number entered on the keypad. The
first digit specifies the switcher (0-9), the second specifies the slot (1-9). Note
that the projector is always considered “switcher #0”.
(;$03/(6=
,QSXW = use source connected to switcher #1, slot #3
,QSXW = use source connected to the projector, slot #1 (i.e.,
 ,QSXW4)
You can switch to an input in either one of two ways. Pressing the appropriate
direct key — 
,QSXW4,  ,QSXW5,  ,QSXW6, or ,QSXW7 — is a quick and seamless way to
display from one of the four inputs at the front of the projector. Or, if your
projector has a switcher connected to it at the 
6:,7&+(5 port, press the general
,QSXW key and enter the 2-digit number representing the switcher and slot location
for the desired signal (note there is no on-screen feedback).
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 adjust anything), the projector will recognize the input signal based on its
frequencies and polarities, and will automatically display the image according to
default settings for such a signal. It will resize as needed, producing an image as
large as possible while maintaining the original aspect ratio.
If you used the source once before and changed a display parameter such as
focus, contrast, etc., then a channel was created and still exists in projector
memory (see below). Using an 
,QSXW key will automatically recall this channel 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 in the channel list. (GLWLQJ#1XPHULFDO#9DOXHV

&+$11(/#0 A channel is a collection of measurements and settings that tailor a
display to your specific needs. Since source types and applications vary greatly,
you will likely want to adjust and define a wide variety of parameters, such as
brightness, contrast, tint, etc., in order to customize and maximize the display
coming from that 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 vary from another used earlier through the
same input location. Once you have adjusted a display parameter, such as zoom,
focus, or pixel tracking, all current settings are collectively stored in the
projectors memory as a unique 2-digit channel, such as 
. You can have
numerous distinct channels to select for the same input, any of which can be
used by using the 
&KDQ key on the keypad.
NOTE: The precise function of the 
&KDQ key is flexible
and depends on how you have defined it from within
the 
Preferences menu (see 
Preferences later in this
section). Shown at right is an example of a channel list
from 
&KDQ.
In order to use channels (
&KDQ on the keypad), you must first create them. See
below.
To use a new source with Vista
GRAPHX 10K, a new channel must be added to
your system so that the projector will respond properly to input from that source
in the future. A new channel can be created automatically, which is the easiest,
or you can use the New button in the Channel List menu.
A channel is automatically created when an input signal is sent to the projector
for display and you then change a parameter (such as adjusting brightness, etc.).
The channel# assigned to an automatically created channel will be the highest
available number from 99 down. Note that automatic channels do not appear by
default in any channel list that may appear whenever you press 
&KDQ — you must
first enter a checkmark for the In Menu option in the Channel List menu for
each automatic channel that you want to list.
You can also define a channel from within the Channel List menu accessed from
the Main menu. This procedure is as follows:
From the presentation level press 
0HQX to display the main menu. To display the
Channel List menu, press 
, or move the highlight to the Channel List icon and
press 
(QWHU.
The Channel List (Figure 3-8) displays a table of all defined channels and how
they are connected to the projector. The numbers in the far left column represent
each channel number defined so far, automatic or not. Other columns list details
pertaining to each channel setup, such as its name, switcher number, slot location
and other information.
The last two columns in the Channel List menu list the frequencies and polarity
(“ + ” or “ - “) detected for each channel signal. If neither symbol is present,
there is no sync.

Beneath the Channel List window, select the New button, which will store the
current signal as a channel with the following defaults assigned:
· channel number = the lowest unassigned number (up to 99).
· switcher (SW) number = 0 (represents the projector itself). Or, if the input
source is connected to a switcher, the default will be the lowest switcher
number available (from 1-9).
· slot (SL) = 1 (
,QSXW4), 2 (,QSXW5), 3 (,QSXW6), or 4 (,QSXW7) for projector inputs, or
current slot number (1-9) if the source is connected to a switcher.
· InMenu = checked. The source will then appear in the channel list whenever
&KDQ  key is pressed.
· AutoSource = checked. The projector will be able to automatically find this
channel on power up if the input signal matches.
· Locked = unchecked. Settings for the channel can be changed.
If you define a new channel without a signal present, the projector memory
remains uninitialized until you Update the setup with an actual signal. See
Updating a Channel below.

sampled. Proper pixel tracking ensures that the image is of the correct proportion
and not stretched or compressed from left-to-right.
NOTE:  By default, the projector samples at the correct frequency for a given
source. For best results, it is recommended that this default not be overridden.
Pixel tracking is adjusted most effectively using a good test pattern, such as a
smooth gray image made up of a clear pattern of tiny black and white dots, or a
similar graphic image. Steady flickering or several soft vertical stripes or bands
across the entire image indicates poor pixel tracking. Adjust the slidebar up or
down until the stripes broaden to the point where one large stripe fills the image.

Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming
signal. It is used primarily for adjusting RGB inputs.
NOTE: Adjust pixel phase after pixel tracking is properly set.
Adjust pixel phase when the image (usually from an RGB source) shows
shimmer or “noise”. Pixel phase adjustment is done most effectively from within
a proper test pattern, such as a smooth gray image made up of a clear pattern of
tiny black and white dots, or a similar graphic image. Adjust until the image is
stable and each dot is clearly defined. Using the numbers on the slidebar as a
guide, you will notice that you can actually stabilize the image at more than one
point—i.e., you may find that the image appearance at 11 is the same as the
image appearance at 38, thus you can select either setting.
