Typical Dynamic Scaling Procedure
STEP 1  
 
Set both Horizontal Margin and Vertical Margin to “0”. The image
will “start” in the upper left corner.
 NOTE: If both margins are set to 0 and the image is still too far to
the right and/or too low, you may have to return to the Size &
Position menu and change the main Horizontal Position and
Vertical Position.
STEP 2  
 
Set Horizontal Capture and Vertical Capture. These values should
match the resolution of your current source in non-zoom situations,
such as 1024 (H) x 768 (V). Set so that all of the image is displayed
exactly within the display window.
STEP 3  
 
Adjust both Horizontal and Vertical Display so that the image is
sized in each direction as desired for your application.
 NOTE: If the Horizontal Display setting appears to stop
prematurely at too low a setting, it is possible that the current
Horizontal Capture setting is too low and is interfering. If so,
increase the Horizontal Capture first.
STEP 4  
 
If necessary, re-adjust Horizontal Margin and/or Vertical Margin
until the image is placed exactly where you want it.
STEP 5  
 
Repeat Steps 3 and 4 until you are satisfied with both the size and
placement of the image.
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
other controls (above) if you need help in selecting options and accepting
changes. Changes made to the Image Settings menu will be saved when you exit
the menu (press

Figure 3.10. Image Settings Menu
Brightness
(SHORT CUT:    from presentation level.)
Increases or decreases the amount of perceived light in the image (0-100). If
video or data is displayed with a black background, adjust until the background
just changes from black to dark gray.
Contrast
(SHORT CUT:    from presentation level.)
Increases or decreases the perceived difference between light and dark areas of
your image (0-100). If contrast is set too high, the bright parts of the image lose
detail and clarity.  If set too low, the light areas will not be as bright as they
could be and it may be difficult to distinguish between foreground and
background information.
NOTES: 1) For best results, adjust brightness before contrast.  2) If room
lighting changes, it may be necessary to re-adjust both.
Color
(SHORT CUT:    from presentation level.)
Adjusts color saturation level, or the amount of color in a video image. For
example, setting Color to 0 produces a black and white image. If Color is set
too high, the color levels in the picture will be over-powering and unrealistic.
Use 
 or  until the desired color saturation level is displayed. 
						

							OPERATION
VistaPro 2000 Users Manual3-22
Tint
(SHORT CUT:    from presentation level.)
Adjusts color hue to obtain true color reproduction of NTSC video signals. Use
 or  until the you reach optimum balance of red-to-green in your image. It is
best to adjust tint while displaying a proper test pattern — otherwise, it is
recommended that tint remain at its default setting.
Detail
(SHORT CUT:    from presentation level.)
Adjusts the sharpness of the video image. Use 
 or  until the display is as
sharp as possible, keeping in mind that any level of detail above 50% will
increase the level of detail as well as introduce some level of noise in the image.
Set below 50% to filter the signal and remove noise from a noisy source. Keep at
50% to apply no detail.
Color Temperature
Allows a color temperature to be selected from a list of 3200,
5400, 6500, 9300, Custom Global or Custom Local. Color
Temperature is measured in degrees Kelvin and represents
the coloration (reddish or bluish) of the whites displayed by
the projector — the lower the temperature, the more reddish
the whites. Use the following as a guide for most
applications:
Color Temperature (K) Typical Application
3200 theatre
5400 film and film-to-video transfers
6500 most video and computers
9300 some computers with a bluish setting
In specialized applications when none of the temperatures are suitable for the
current source, select Custom Local to affect that source.
NOTE: Selecting Custom Local will apply the specific Custom Local
temperature that may have been determined best for a particular source and
pre-set in the Service menu by a qualified service technician. There may be a
different color temperature available for each source. For more information,
contact your dealer or Electrohome.
In special applications when none of the temperatures are suitable for any of
your sources, select Custom Global. This temperature will affect all sources.
NOTE: Selecting Custom Global will apply the Custom Global temperature
that has been determined best for all sources used and pre-set in the Service
menu by a qualified service technician.

Video Standard
If Auto is checked, the projector will automatically
detect the video standard present and display this standard
in the adjacent box. If Auto is unchecked, press 
 at
the adjacent pull-down list to view or select a different
video standard from a complete list available to the
projector. Selecting a specific standard forces the projector
to process the signal according to this standard. Re-check
the Auto checkbox to return to automatic detection of the standard.
NOTE: This option should remain set at auto for all instances EXCEPT: 1) a
poor quality input signal or 2) a black-and-white video signal. In order to detect
and display such signals, uncheck Auto and specify the relevant standard.
Signal Type
If Auto is checked, the projector will automatically
detect the type of signal present (unless it is RGB-Video
or YUV) and will display the signal type to the left in the
adjacent box. If Auto is unchecked, press 
 at the
adjacent pull-down list to view or select a different signal
type from a complete list available to
the projector. Re-check the Auto
checkbox whenever you want to
return to automatic detection of the
signal type.
NOTES: 1) RGB-Video (which requires
a third-party decoder) and YUV signals
cannot be automatically recognized — if
you use either of these sources, you must select the corresponding signal type from
the list.  2) It is recommended that this option remain set at auto for other signal
types.
VCR
(SHORT CUT KEY:    from presentation level.)
This option determines to what degree the projector tolerates signal disturbances.
Enter a checkmark only if the NTSC 3.58 image generated from your VCR
source appears noisy or unstable, or if the image has a very high level of detail.
Leave blank for all other sources.
Sync Tip Clamping
This option can brighten the image produced from certain high resolution, high
frequency graphic sources. Enter a checkmark if the image appears unusually
dim or if there are horizontal streaks across the image. Delete the checkmark if
the image is either sufficiently bright or overly bright.
NOTE: Does not apply to video sources or any RGB source with sync
information on the video (e.g., sync-on-green).

Figure 3.11. Preferences Menu
Front IR Keypad / Rear IR Keypad
An IR remote keypad is either a Protocal A keypad (the original setting at
manufacture) or a Protocol B keypad. Either protocol may or may not be
recognized by the two sensors on the projector (front and rear), depending on
what option you choose here. If the two sensors are both on, they will recognize
the same protocol (Vista A, Vista B, or both) — changing an option for one
sensor automatically changes the other to match. If you want only one sensor to
respond to a particular protocol (Vista A, Vista B, or both), disable the other
sensor by setting its protocol to OFF.
NOTE: Keypads are set at manufacture to Protocol A. See 2.10, Keypad
Protocols for information about setting keypad protocols.

Wired Keypad
A wired keypad is either a Protocol A keypad (the original setting at
manufacture) or a Protocol B keypad. You can prohibit the projector from
responding to a particular protocol, or you can ensure that the projector responds
to either protocol. You can also prevent the projector from responding to the
keypad. In this menu, select one of the following protocols for the projector:
OFF
The projector will not respond to the
wired keypad.
AThe projector will respond only to a
wired keypad set to protocol A.
BThe projector will respond only to a
wired keypad set to protocol B.
A or BThe projector will respond to a wired
keypad set to either protocol A or B.
NOTE: Keypads are set at manufacture to Protocol A. Please see 2.10,
Keypad Protocols for information about setting keypad protocols.
Baud Rate
The baud rate setting determines the speed of
communications. It is important if you are controlling the
projector with an external device such as a computer or
another projector via an RS-232 port. The VistaPro 2000 baud
rate must be set to match the baud rate of the controlling
device. If you are unsure about what baud rate to assign, refer
to the documentation for the controlling device. By default, the projector baud
rate is set to 9600.
NOTE: 1) The baud rate setting does not affect the switcher port, which remains
at 9600. 2) See 2.9, Serial Port Connections and Appendix D for more
information about cable connections between devices.
Source Selection
Choose how you want to select sources from the 
 key.
Choices are 1-digit entry, 2-digit entry, or a scrollable list of
sources (note that each source to be included in the list must
also be tagged in the In Menu checkbox in the Source Setup
menu).
Image Orientation
Choose from Front, Rear, Inverted Front, Inverted Rear
according to your installation. If the setting is incorrect,
the image will be reversed and/or upside down. See 2.6,
Operating Orientation for an illustrated explanation.

required whenever you want to communicate with a single projector within a
multiple-projector application (see 
 key, above).
For more information about controlling multiple projectors, see Section 3.8.
Display Slidebars
If checked, will allow direct slidebars to be superimposed over the current image
when an adjustable parameter is selected. These slidebars include volume,
contrast, brightness, position, pixel tracking and phase, and others. If unchecked,
direct slidebars (or any from 
 codes) will remain invisible during adjustment.
Lamp Timer Message
If checked, will display a lamp timer message as the lamp in the projector
exceeds its 750-hour life. The lamp timer message will time-out (disappear from
screen) after 30 seconds.
NOTE: For maximum lamp performance and safety, it is recommended that
display of this message remain enabled — enter a checkmark in the checkbox.
Error Messages
If checked, on-screen messages will notify you of errors as they occur. See 3.9,
Error Messages.
Opening Screen
If checked, an opening screen such as the Electrohome VistaPro logo will be
displayed upon power up until a source is selected.
Video Termination
Check this option to terminate the video input (75 
S). The input should be
terminated unless the signal loops through (continues) to another projector or
display device, in which case the last projector in the chain should be terminated.
Auto Power up
If checked, the projector will automatically power up without pressing 
.
Note that unsaved display adjustments may be lost after a power failure.
Broadcast Keys
Check if you want keypad commands sent to one projector to be relayed to all
projectors in a network. The 
   command on the built-in keypad (or 
on remote keypads) will still allow you to control a specific projector.
This primarily read-only menu (Figures 3.12 and 3.13) consists of four separate
read-only menus plus a text editing box used for entering the serial number of a
new lamp. The four menus list a variety of details about the standard and
optional components currently in use on the projector. 
Refer to these menus for
information about hardware and software versions installed, number of lamp
hours logged, and projector model and serial number. In addition, the Status
Menu identifies the current source, switcher, slot and frequencies present. Call

Recording the serial number of the new lamp automatically resets the lamp timer
to 0 to reflect the number of hours the lamp has been used. The timer will now
begin logging each hour of use for the new lamp, recording the current level in
the main Status menu. See 4.4, Replacing the Lamp and Filter for complete
instructions on installing a new lamp assembly.
WARNING
If you enter a serial number and select the Accept
button WITHOUT having installed a new lamp, the
timer will incorrectly return to 0 and will therefore
no longer be accurate. The old lamp may expire
without warning.
NOTE: Once entered, the new lamp serial number is also automatically added to
the Lamp History list of lamp serial numbers in the Service menu (password-
protected).
The Service menu is password-protected and can be used by qualified service

When working with multiple projectors, you may want to use the RS-232 ports
to chain the projectors together in a network that you control from either a
keypad or a computer/controller (see 2.9, Serial Port Connections). Or you may
prefer that each projector stands alone, in which case you will probably use a
single IR remote keypad. In either case, you can switch back and forth between
broadcasting to all projectors or controlling each projector individually.
Make sure you have assigned a unique projector number to each projector
present — this number will be required in order gain the exclusive attention of
an individual projector. To assign a projector number: Service

In the Preferences menu, scroll down to Projector# and enter a three-digit
number (000 to 999) to identify the current projector. Press 
 to accept the
entry and return to the main menu.
Repeat for each projector, using a unique three-digit number for each. Once
every projector has its own number, you can begin to control the network.
If you are using an IR remote, press 
 to display an editable window. Enter
the three-digit number you have assigned to the projector you wish to control.
All keypad commands will then affect this projector exclusively until you press
 again and enter a different number, or
until you switch to broadcast mode (below).
If you are using a wired remote keypad
(optional) in a network of projectors, make sure that the projector to which the
keypad is connected has its “Broadcast Keys” option checked. Press 
 to
bring up the editable box. Enter the three-digit number assigned to the projector
you want to control — keypad commands will now affect only the desired
projector until you press 
 again and enter a different number, or until you
switch to broadcast mode (below).
NOTES: 1) If you are using a computer or controller to issue commands, use the
correct RS-232 software command to gain control of a single projector.
On the IR remote or wired keypad, press 
 to display the projector box. Press
 without entering a number — the keypad commands will now affect all
projectors.
Make certain that only one projector has its Broadcast Keys option selected
(checked) — the remaining projectors should have the option unchecked and
their keypads disabled (do this in Preferences menu). The Broadcast Keys
projector will then relay keypad commands to the others. If using a wired
remote, make sure to select the “Broadcast Keys” option for the projector to
which the wired remote is connected.
NOTE: 1) If you are using a computer or controller to issue commands, use the
correct RS-232 software command to broadcast.
