Your Projector has a 2x zoom lens. This
means that the picture you get on the
screen at maximum magnification is twice
as big as that projected at minimum
magnification. For example, at a distance
of 22 feet you get a 100-inch picture on
the screen at full magnification. You can
use the zoom lens to reduce this to 50
inches at minimum magnification.
If you want a picture size of 100 inches,
the Projector can be between about 22
and 44 feet from the screen. Choose a
screen and projection distance in the
middle of the zoom range (mid-range
magnification). This gives the best
picture quality and means you can fit the
picture exactly to your screen by zooming
in or out a little.
The table alongside shows you typical
picture sizes at various distances. More
information is given in the "Technical
Specification" on page 40.
3) Choose the type of screen
Choose the type of screen-mount you
prefer (stand type, wall-mount, pull-down
etc).
Choose a screen with a width to height
ratio of 4:3 (aspect ratio of 1.33) to match
the NTSC picture format. A black
masking border around the screen will
give a crisp rectangular picture.
The picture appears brightest (highest
gain) when you sit directly in front of it
and gets dimmer as you move to the sides.
Try to keep the viewing angle as narrow
as possible for most viewers.
Choose the type of screen surface best
suited to your room and viewing
conditions:
Pearlescent - highest gain, narrow
viewing angles.
Silver lenticular - medium gain, wide
viewing angles. This type of screen is not
recommended.
Matt white - wide viewing angles, needs
darkened room.
Polarized - By using this type of screen,
the contrast in a light environment can
be improved.
If in doubt, consult your dealer on the
best choice of screen for your room.

Larger picture sizes can be reached by putting the Projector at a
greater distance.
For best results, choose your screen and projection distance using
mid-range magnification of the zoom iens.
