Using a 5:4 Screen with “S” Models
With one exception, XGA images will—
by default—resize to fill an SXGA screen
with “S” models. The exception
(illustrated in Figure 2.7) is that video
signals will retain their aspect ratio—fill
the screen by increasing Vertical Stretch
to slightly expand the image to the top and
bottom edges of the screen. For details,
see 3.6, Adjusting the Image.

To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2.9 shows an
installation where poor screen placement allows too much unwanted light to enter the
screen. In Figure 2.10, screen and the projector are positioned so that unwanted light
is minimized.

• 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:
◊ As screen size increases, magnification increases and reduces brightness.
Select a screen size which is appropriate for the venue, but not larger
than that required.
◊ Installing a large screen in a small room is similar to watching television
close up; too large a screen can overpower a room. A...

Throw distance is roughly equal
to the horizontal width of the
screen multiplied by the type of
lens you are using. For example,
if you are using a 0.8:1 lens,
proper throw distance will be
approximately 0.8 
x the screen
width. Once you know your
screen size and lens, you can
estimate throw distance needed
(see example in Figure 2.12).
IMPORTANT: For proper
placement in an installation,
always refer to the throw distance formula and/or graph for...

NOTES: 1) If you cannot raise or
lower the image enough using
mechanical vertical offsets, try
adjusting V-Position in the Size
and Position menu (see 3.6,
Adjusting the Image). 2) If the
image becomes keystoned or
exhibits uneven brightness, the
projector may simply be too high
or low in relation to the screen. 3) Recommended offset ranges can be exceeded,
however this may affect image...

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.
The table or cart should be reasonably level. Fine adjustments to the projector level
can be made by adjusting the height of the projector legs; refer to 2.7,...

In rear screen applications where space behind
the projector is limited, a mirror may be used
to fold the optical path. See right. The position
of the projector and mirror must be accurately
set—if considering this type of installation, call
your dealer for assistance.
The rear panel of the projector provides standard input panels to which you may
connect a variety of sources. See Figure 2.16–the lower left area (
INPUT 1) typically
accepts an RGB...

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources, typically to
an RGB source such as VGA, SVGA, XGA, Mac, PowerMac, DEC, Sun, SGI and
others. This projector supports multiple sync types with RGB signals: sync-on-green,
composite sync, and separate H & V syncs.
NOTE: Depending on the source, you may need a custom adapter cable with BNC
connectors at the projector end and a different type of connector at the other (such as
a...

Connect a YPbPr signal (component video) to INPUT 1 as shown in Figure 2.18.
Figure 2.18. Connecting YPbPr Signal
NOTES: 1) If, for some reason, the projector fails to recognize a YPbPr signal,
specify this Color Space option within the Image Settings menu. See 3.6, Adjusting
the Image. 2) Do not connect digital component signals (known as YCbCr) to 
INPUT
1
. Use the appropriate digital interface installed at INPUT 2.
