Introduction
VistaPro 2000 Users Manual 1-1
VistaPro 2000 is a professional-quality DMDÔ projector that uses Digital Light
Processing
Ô from Texas Instruments to achieve high-brightness multimedia and
video projection. It is ideal for use in large audience venues in which there may
be high levels of ambient light, such as in auditoriums and lecture halls. The
VistaPro 2000 is compatible with standard international video formats and can
interface with IBM-compatible PCs, Macintosh
Ò and computer workstations.

à 848 x 600 pixels resolution
à 2000 ANSI lumens
à interchangeable lenses
à diagonal screen size up to 30 feet
à NTSC, PAL and SECAM compatible (export model requires optional decoder)
à displays input from PCs, VCRs, laser-disc players, video cameras, etc.
à intuitive on-screen menus
for setup and control
à built-in and infrared (IR)
remote keypads
à controller and switcher
compatibility
à keypad selectable input

à RS-232 input with loop-
through for networking
multiple projectors
à 5-language capability
à modular design for ease of servicing
VistaPro 2000 accepts data/graphics and video input signals for projection onto
flat or curved front or rear projection screens. High brightness light is generated
by an internal 1 kilowatt CERMAX
Ò Xenon lamp. This light is modulated by
three DMD (digital micromirror device) panels which each provide digitized red,
green, or blue color information. Light from the ON pixels of each panel is
reflected, converged and then projected to the screen through a single front lens,
where the pixels are all superimposed to create a sharp full-color image.
The projector body is comprised of powder-coated aluminum and an ABS front
bezel. Covers can be removed as necessary for quick replacement of the lamp or
filter. The projectors modular internal design provides for ease-of-service and
minimal down-time.

Installation & Setup
VistaPro 2000 Users Manual 2-1
This section explains how to install and set up the projector.  If you are familiar with the projector and want to
quickly set it up for temporary use, follow the Quick Setup instructions. For a complete setup, follow the
instructions and guides covered in the remaining subsections.
NOTES: 1) The lens for the projector is not mounted when shipped from the factory. For instructions on how to
install or replace a lens, refer to 4.5, Replacing the Lens. 2) This manual assumes the video decoder is installed.
Follow these 6 steps for quick setup of the VistaPro 2000.
Position the Projector
Set the projector at the proper throw distance (projector-to-screen distance) and
vertical position. See 2.3, Projector Position and Mounting. Make sure that the
projector is level from side-to-side (see 2.7, Leveling).
Connect a Source
Locate the input panels at the rear of the projector. The upper right panel accepts
an RGB input (via BNC connectors). The lower left panel accepts a composite
video and S-video input. Connect a source to the appropriate panel.
Connect the Line Cord
Plug the special notched AC line cord (power cord) into the AC power socket at
the left rear of the projector. This cord is rated at 15 amps rather than the 8-10
amps in other typical cords. Input power required is 100 VAC to 240 VAC, 50 to
60 Hz @ 11 amps.
WARNING:
 Use only the special notched AC line cord. Do not
attempt operation if the AC supply is not within the
specified voltage and power range.
Turn the Projector ON
Using either the built-in or IR remote keypad, press 
 and hold for a second
to turn the projector on. The VistaPro logo will be displayed after a brief delay.
Let the projector warm up for five minutes.
Select a Source
Using either the built-in or IR remote keypad, press

Make Necessary Display Adjustments
With the input image displayed, rotate the lens barrel to increase or decrease
image size (applies to zoom lenses only). Then rotate the nearby Vertical Offset
knob to achieve the best overall image position and brightness without a
distortion in picture geometry. Next, rotate the focus adjustment knob (next to
the lens barrel) to achieve best focus. Press 
 to refine other display
adjustments, press
 
 if you want to select a different source. See 3.5, Using
Sources.
Although VistaPro 2000 delivers a high brightness quality output, the final
display quality could be compromised if the projector is not properly installed.
This subsection discusses issues you should consider before proceeding with a
final installation. Even if you do not intend to use VistaPro 2000 in a fixed and
permanent installation, this subsection will help you to better understand what
may be done to enhance display performance.
Choose the installation type which suits your needs: front or rear screen, floor
mount or inverted mount.

Screen type is important when designing a projection system. Inexperienced
users or installers should always consult their dealer when deciding on screen
type. The following guidelines explain the differences between screen types. STEP 6

Screen Type

VistaPro 2000 Users Manual2-3
Front Screen Installations
There are two basic screen types: flat and curved. The choice between a flat
screen or a curved screen is dependent on audience viewing angle and screen
gain. There is always a trade-off between viewing angle and gain. Viewing
angles for both screen types are illustrated in Figures 2.1 and 2.2 (plan views).
Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all directions so the audience can see the display
from various angles. Because of the lower gain, flat screens are more effective
when ambient lighting is reduced.
Figure 2.1. Audience Coverage with Flat Screen
Figure 2.2. Audience Coverage with Curved Screen
Curved screens have gains larger than 1 (due in part to the screen material) and
viewing angles much less than 180°. Most curved screens have different
horizontal and vertical viewing angles. Incident light does not reflect equally in
all directions. The reflected light concentrates in a conical volume or viewing
cone. Audiences within the viewing cone see a brighter image than that from an
equal area on a flat screen. Audiences outside the viewing cone see a dimmer
image.
NOTE: VistaPro 2000 lenses are designed primarily for use with flat screens.
However, its depth-of-field range allows the lens to be focused on curved
screens as well. Focus remains sharp in the corners, however there may be
significant pincushion distortion, primarily at the top of the screen.

VistaPro 2000 Users Manual2-4
Rear Screen Installations
There are two basic types of rear screens: diffused and optical. A diffused screen
has a surface which spreads the light striking it. Purely diffused screens have a
gain of less than 1. The main advantage of the diffused screen is its wide viewing
angle, similar to that of a flat screen for front screen projection. Optical screens
take light from the projector and redirect it to increase the light intensity at the
front of the screen. This reduces it in other areas. A viewing cone, similar to that
of a curved front screen installation, is created.
To summarize, optical screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone. Diffused screens are best suited
when a wide viewing angle is required but there is low ambient room lighting.
Screen size may be from 8 to 30 feet diagonal (2.4 to 9.1 meters) for projector
models with 5:1, 1.5:1 - 3:1 (zoom), and 3:1 - 7:1 (Zoom) lenses. If the projector
has a 1.2:1 lens, screen size can range from 5 to 25 feet diagonal (1.5 to 7.6
meters). Choose a screen size which is appropriate for your lens and application.
If the projector will be used to display text information, the image size must
allow the audience to recognize all text clearly. The eye usually sees a letter
clearly if eye-to-text distance is less than 150 times the height of the letter. Small
text located too far from the eye may be illegible at a distance despite the image
being projected sharply and clearly on the screen.
To fill a screen with an image, the aspect ratio of the screen must be equal to the
aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of
its width to its height. Standard video from a VCR has a 4:3 or 1.33:1 aspect
ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10 foot
(3m) high screen, the width of the screen must be at least 13.3 feet (4m).
Note: Screen size is often specified as diagonal size. Screens specified by
diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are not
typically specified by diagonal size.
The high brightness output of VistaPro 2000 is well suited for locations where
ambient lighting is less than optimum for projection; however, it is desirable that
the projector be operated in an ideal projection room environment. For
temporary installations where the room may not be designed for projection, there
are many simple things which can be done to avoid problems caused by
unwanted light.
Visiting a movie theater can give you an idea of what makes a good projection
environment. Walls, floors and furnishings are dark and matte finished. A
projection room should not have white reflective ceilings or non-directional
lighting such as fluorescent lights. The white ceiling spreads light, making the
room appear brighter. Keep lighting and reflections to a minimum.
If it is not possible to eliminate fluorescent lights, consider using parabolic
reflectors (egg crates) to direct light down to the floor. Incandescent spot
lighting is a better way to obtain illumination. Light dimmers or rheostats allow
you to further control the lighting. Screen Size

Room Lighting 
						

							INSTALLATION & SETUP

Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have
windows, make sure that window coverings are opaque and overlapping — some
window coverings are designed to provide up to 100 percent blockage of outside
light. Ideally, the material should have a matte finish.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2.3 shows an
installation where poor screen placement allows too much unwanted light to
enter the screen. In Figure 2.4, the screen and the projector are positioned so that
unwanted light is minimized.
Figure 2.3. Poor Screen Placement
Figure 2.4. Better Screen Placement
Even with all lighting removed it is still possible that room reflections within the
room can degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to
the screen. Again, reflective surfaces should be kept to a minimum.
Here are some other considerations and tips which can help you improve your
installation:
· Ventilation is an important factor when preparing a projection room. The
ambient temperature should be kept constant and below 35°C (95°F). Keep
the projector away from heating and/or air conditioning vents. Changes in Other Considerations
 
						

							INSTALLATION & SETUP
VistaPro 2000 Users Manual2-6
temperature can cause drifts in the projector circuitry which may affect
performance.
· Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide
projectors, speakers, power amplifiers, elevators, etc.
· For rear screen applications, less space is required if a mirror is used to fold
the optical path.
· Choose the right screen size for the application:
à As screen size increases, magnification increases which reduces
brightness. Select a screen size which is appropriate for the venue,
but not larger than that required.
à Installing a large screen in a small room is similar to watching
television close up; too large a screen can overpower a room. A good
rule of thumb is to be no closer than 1.5 times the width of the
screen.
à Larger screens require greater attention to lighting conditions.
· When laying out the projection room, consider positioning the projector and
screen in a manner which will achieve maximum audience coverage and
space efficiency. For example, placing the screen along the larger wall in a
rectangular room will reduce audience coverage. Figure 2.5 shows two
examples of how audience coverage is maximized.
Figure 2.5. Screen Locations for Maximum Audience Coverage
As mentioned, installation type, screen type, and lighting all affect where the
projector is positioned. In addition, both throw distance (the distance between
the projector and screen) and vertical position must be determined for every new
installation. Both are calculated based on screen size and projector lens type.
Make sure that the room can accommodate the required position of the projector
for the chosen screen size.
Throw distance is the distance between the projectors front feet and the screen
(measured perpendicular to the screen and projector, not necessarily parallel to
floor). As the distance between the projector and the screen increases, image size
also increases.2.3 Projector
Position
and Mounting
Throw Distance 
						

							INSTALLATION & SETUP
VistaPro 2000 Users Manual2-7
Throw distance is roughly equal to the width of the screen multiplied by the type
of lens you are using. For example, if using a 1.2:1 lens, throw distance should
be roughly equal to 1.2 
x the screen width. Once you know your screen size, you
can determine how far away the projector should be:
Table 2.1
Lens Type Approx. Throw Distance
5:1 5 x screen width
1.2:1 1.2 x screen width
1.5:1 -  3:1 1.5 x screen width up to
3 x screen width
3:1 - 7:1 3 x screen width up to
7 x screen width
NOTE: Throw distance is measured perpendicular to the screen and projector,
not necessarily parallel to the floor. It is good practice to simulate the setup with
the projector fully warmed-up to determine the actual throw distance required.
The vertical position of the projector in relation to the screen also depends on the
size of the screen and the lens type. Correct vertical position ensures that the
image will be rectangular in shape rather than keystoned (having non-parallel
sides). Vertical position can be offset up or down using the vertical adjustment
knob on the front of the projector. The vertical offset range of a projector with a
fixed lens is shown in Figure 2.6. Maximum offset with a zoom lens is 75%.
Figure 2.6. Projector Position and Vertical Offset Range with Fixed Lenses
For typical front or rear floor mounts, mount the projector
on a secure table or cart. Take care with a mobile cart—
avoid sudden stops, excessive force and uneven surfaces that
may cause the projector and cart combination to overturn. Vertical Position
