NOTE: See Section 2, Installation and Setup, for a full explanation of how to
connect sources to the VistaPro 2000.
When you first use a source with the VistaPro 2000, you may want to adjust and
define a wide variety of parameters, such as brightness, contrast, tint, etc., in
order to customize the display for 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. Once defined, the settings for a particular
source are collectively stored in the projectors memory as a unique source
setup. VistaPro 2000 stores and automatically recalls up to 80 source setups so
that you do not have to repeatedly re-configure the projector when returning to a
previously used source. Note that you can have more than one source setup for
the same physical source.
You can switch to a specific source in either one of two ways. Pressing the
appropriate direct key (
 ,   ,    or  ) is a quick and seamless
way to display the image for that source. Or, perhaps if your system includes
additional sources, you can press 
 to use one of three
other methods of source selection, such as a pull-down list
of all sources (default). Note that the precise function of
the 
 key is flexible and depends on how you have
defined it from within the Preferences menu (see
Preferences, below).
NOTES: 1) In 1- or 2-digit source selection, VistaPro 2000 time-outs after 5
seconds of inactivity, selecting the current source and returning to the previous
menu. 2) From presentation level, press  
 or  to cycle through the list.
Regardless of which method you use to select a source, the image will be
displayed according to the parameters (the source setup) last defined for that
source. If you have not yet defined any parameters, a new source setup is
temporarily defined according to a default mode table defined in the projector.
This will not be saved as a new source setup unless you change a parameter.
To use a new source with VistaPro 2000, a new source setup must be added to
your system so that the projector will respond properly to input from that source
in the future. A new source setup can be created automatically, or you can use
the New button in the Source Setup menu.
A source setup is automatically created when an input signal is sent to the
projector and parameters are changed. The source# assigned to an
automatically created source will be the highest available source number from 99
down. Automatic source setups will not appear in any source list that may appear
whenever you press 
 — you must first enter a checkmark for the In Menu
option in the Source Setup menu.
You can also perform a source setup from within the Source Setup menu
accessed from the main menu. This procedure is as follows:
From the presentation level press 
 to bring up the main menu. Highlight the
Source Setup icon and press 
 to call up the Source Setup menu.

The Source Setup menu (Figure 3.8) displays a table of any defined source
setups and how they are connected to VistaPro 2000. The numbers in the far left
column represent each source setup defined so far. Other columns list details
pertaining to each setup, such as its source name, switcher number, slot location
and other information.
The last two columns in the Source Setup menu list the frequencies and polarity
(“ + ” or “ - “) detected for each source signal. If neither symbol is present, there
is no sync.
Use the scroll bar to see and work with any additional sources not visible in the
table.
Figure 3.8. Source Setup Menu
Beneath the Source Setup window, select the New button, which will store the
current signal as a source setup with the following defaults assigned:
· source number = the lowest unassigned number (up to 99).
· switcher (SW) number = 0 (represents the projector itself). Or, if the
source is connected to a switcher, the default will be the lowest switcher
number available (from 1-9).
· slot (SL) = 1 (
), 2 (), 3 (), or 4 () if there is no switcher,
or current slot number (1-9) if the source is connected to a switcher.
· InMenu = checked. The source will then appear in the source list whenever
  key is pressed.
· AutoSource = checked. The projector will be able to automatically find this
source on power up if the input signal matches.
· Locked = unchecked. The source setup can be changed. STEP 2

If you define a new source setup without a signal present, the projector memory
remains uninitialized until you Update the setup with a signal present. See
Updating a Source Setup below.
Repeat Steps 1 and 2 for each remaining new source you wish to add. Press 
or  on the keypad to accept all new sources defined.
You can edit the setup information assigned to a source. For example, you can
enter text for the source name (such as VHS#1 or My PC), or you can
change the switcher number, slot number, etc. pertaining to a specific source.
From the presentation level press 
 to bring up the main menu. Highlight the
Source Setup icon and press 
 to call up the Source Setup menu.
Highlight and select the center button at the bottom of the
screen. From the pull-down list, select Edit. This will turn this
button into an Edit button until you select a different option
— Copy, Delete, or Update — from the list.
NOTE: For quick access while in the first four columns of the Source Setup
window, use 
 for Edit,  for Copy, and   for Delete.
Using the arrow keys, return to the setup window above the Edit button and
select the desired source. Edit as necessary to accurately reflect your source
connections:
· Source#:
 Enter any new valid source number from 1-99. If the number you
choose has already been assigned, a message box will appear upon exiting
the source setup window. Either cancel and enter a different number or
overwrite the old source.
· Source Name: Enter a maximum of twenty characters to describe your
source (see Editing Text, above)
· Switcher#: Enter 0 if the signal is physically connected to the projector
itself. Enter 1-9 if the signal is physically connected to a switcher.
· Slot#: Enter 1-9 for a specific slot on a switcher or 1-4 for a connection to
the projector itself.
· Checkboxes: Toggle any checkboxes as desired for the source.
Repeat for each source you wish to edit. Press 
 or  (using keypad) to
accept all editing.
Highlight and select the center button at the bottom of the screen.
From the pull-down list, select Copy. This will turn this button
into a Copy button until you select a different option — Edit,

Select OK only if you really
want to delete all sources,
regardless of whether they are
locked or not.
NOTE: You cannot delete the current source with Delete or Delete All.
To update a new source so that the projector will be able to lock
on to this source in the future, highlight and select the center
button at the bottom of the screen. From the pull-down list, select
Update. This will turn this button into an Update button until
you select a different option — Edit, Copy, or  Delete —
from the list.
Using the arrow keys, return to the main source setup listings above the
Update button and select the source setup you wish to update. The setup will
change to reflect any new settings, recognizing the horizontal and vertical scan
frequencies and recording them in the last two columns.
All image control functions can be accessed in two menus: Size and Position and
Image Settings, each of which is called up by its own triangular icon in the main
menu. Or, if desired, you can call up individual menu functions directly from
presentation level by pressing the 
 key followed by the appropriate two-digit
number listed on the back of the remote keypad (and shown below).
While in either of these two menus, you can change settings affecting the image
from the current source by working with the appropriate slidebars, checkboxes
and  pull-down lists.  
 will always return to presentation level and accept any
changes you may have made within a menu. If at any time you want to cancel
changes you have made and instead revert to the last saved settings for the
current source, select the on-screen Revert button.
Using the arrow keys for navigating, highlight and select any of the following
slidebars or pull-down lists to alter your image. Refer to Using slidebars and

changes. Changes made to the Size & Position menu will be saved when you exit
the menu (press 
).
Figure 3.9. Size & Position Menu
Horizontal Position
(
SHORT CUT:    from presentation level.)
Moves picture right and left.
NOTE: The number on the slidebar represents where the approximate center of
the image lies in relation to the total number of pixels available horizontally and
varies widely according to the signal. Watch the image while adjusting.
Vertical Position
(SHORT CUT:    from presentation level.)
Moves picture up and down.
NOTE: The number on the slidebar represents where the approximate center of
the image lies in relation to the total number of lines available vertically and
varies widely according to the signal. Watch the image while adjusting.
Pixel Tracking
(SHORT CUT:    from presentation level.)
Adjusts the frequency of the pixel sampling clock, indicated by the number of
pixels per line, so that all pixels generated by a particular source are sampled.
Proper pixel tracking ensures that the image is of the correct proportion and not
stretched or compressed from left-to-right. 
						

							OPERATION
VistaPro 2000 Users Manual3-17
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.
Adjustment of pixel tracking is done most effectively from within 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
(SHORT CUT:    from presentation level.)
Adjusts the phase of the pixel sampling clock relative to the incoming signal.
Primarily used for adjusting RGB input.
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.
Top, Bottom, Left or Right Blanking
(SHORT CUT:     —     from presentation level.)
Blanks (turns to black) the top, bottom, left, or right edge of the image so that
any unwanted information is hidden. Blanking may be required for any signal
that does not fill the 848 x 600 pixels available on the VistaPro 2000
.
Resizing Factor
(SHORT CUT:    from presentation level.)
Enlarges or reduces the size of the image by the ratio
specified (1 represents the original image size). To enlarge
an image, select an option in which one of the numbers is larger than 1. For
example, to increase the size of an image by 25%, select the 1:1.25 option. To
reduce image size, select an option in which one of the numbers is smaller than
1. For example, to reduce an image to 78% of its original size, select the
1:0.78 option. Note that correct proportion is maintained when applying ratios.
Unlike these numerical ratios, the anamorphic option stretches the horizontal
more than the vertical (at a ratio of 4/3). The anamorphic option corrects the
appearance of those video formats that resemble standard NTSC in most
respects, but which have been compressed horizontally by a ratio of 3/4. 
						

							OPERATION
VistaPro 2000 Users Manual3-18
Dynamic Scaling is yet another option in the Resizing Factor pull-down list.
Selecting this option generates a separate submenu of controls as described
below.
When to Use Dynamic Scaling
Like the numeric resizing ratios, dynamic scaling allows you to increase or
decrease the size of your image. With dynamic scaling, however, you can also
control the horizontal and vertical sizes independently and move the image to a
specific area of the screen. Use dynamic scaling in order to match your image
precisely to the specific screen size and aspect ratio (proportion) present in your
application.
Note that only sources recognized as “non-video” can be adjusted through
dynamic scaling, such as graphics RGB signals and line-doubled (or better)
video signals. While images from NTSC, PAL, or SECAM signals can be
adjusted through dynamic scaling if the signal first runs through a separate line-
doubler (or better) before reaching the projector, the frequencies of these signals
in their initial state (NTSC = 15.73 kHz / 59.94 Hz, and PAL/SECAM = 15.62
kHz / 50.00 Hz) will be recognized by the projector as video only—dynamic
scaling will not be possible until their frequencies are changed to non-video
through line doubling.
How to Access & Adjust Dynamic Scaling
The three sets of horizontal/vertical
dynamic scaling controls reside in
their own submenu called Dynamic
Scaling (see right). Access this
submenu through the “
Resizing
Factor
” pull-down list in the Size &
Position menu—select the
“
Dynamic” option.
Note that the 
   shortcut to
the “
Resizing Factor” pull-down list
does not permit access to this menu
but instead applies whatever
dynamic scaling values have
previously been set for the current
source (which will be defaults for
the current source, if never set).
Each control in the dynamic scaling menu is described below, followed by a
typical step-by-step dynamic scaling procedure. For all adjustments, use the 
or  keys to increase or decrease. Press  to accept the changes and return
to the Dynamic Scaling submenu (or 
 to return to presentation level). Dynamic Scaling

Horizontal Margin
Moves the image left or right, essentially by displacing it with the left margin
amount you specify. When adjusted as far as possible to either side, the image
aligns with the edge without loss or wrapping to the opposite side. Note that the
margin is limited by the size of the image set in Horizontal Display, below.
Range: 0-240 pixels
Vertical Margin
Moves the image up or down, essentially by displacing it with the top margin
amount you specify. When adjusted as far as possible up or down, the image
aligns with the edge without loss or wrapping to the opposite edge. Note that the
margin is limited by the size of the image set in Vertical Display, below.
Range: 0-255 lines
Horizontal Display
Stretches or compresses the image horizontally. The value you choose for this
setting determines how many pixels are used across the image. Note that the
horizontal display setting cannot be more than twice the horizontal capture
setting.
Range: 1-848 pixels
Vertical Display
Stretches or compresses the image vertically. The value you choose for this
setting determines how many lines from top to bottom are used for displaying the
image.
Range: 1-600 lines
Horizontal Capture
Determines what portion of the image is displayed horizontally, much like a
horizontal zoom function. The higher the setting, the smaller the image. The
horizontal caption setting represents the number of active pixels present across
the image—i.e., this value should match the horizontal resolution of your current
source in non-zoom situations. Note that the horizontal capture setting cannot be
less than half of the Horizontal Display setting.
NOTE: The adjustment increments represent individual pixels, however the
image changes at 16-pixel increments only.
Range: 320-1024 pixels
Vertical Capture
Determines what portion of the image is displayed vertically, much like a zoom
function. The higher the setting, the smaller the image. The vertical capture
setting represents the number of active lines present from top to bottom—i.e.,
this value should match the vertical resolution of your current source in non-
zoom situations.
Range: 2-1024 lines
