Note
• A Polarized screen can not be use for this LCD Projector, because its polarizing effect will add to the polarization
already designed into the Projector (to increase its efficiency). The resulting image will not appear in its true
color.
This type of screen can be seen from anywhere,
so there are no limits on the viewing position.
However, the surrounding walls should be
darkened as in a movie theater, otherwise a
clear picture cannot be obtained.
This type of screen gives a picture which is 2-4
times brighter than a white screen. A variety of
types are available from different manufacturers,
and each type has different brightness
characteristics. Some also have restrictions on
the possible range of viewing positions.
* Care should be taken with screens that have
a high gain, as these types of screen can
cause color distortion at the left and right
edges.
* This type of screen is recommended when the
Projector is suspended from the ceiling.
This type of screen is similar to the silver
screen, except that no color distortion occurs
at the left and right edges. Moreover, most of
the light is reflected at the same angle as the
angle of incidence.
* This type of screen is recommended when
the Projector is placed on the floor.
This type of screen is made of PVC (polyvinyl chloride).
It has the same characteristics as silver screens, but sometimes it can have hot
spots.
This type of screen is made of acrylic plastic.
It is extremely durable and has excellent optical characteristics. It performs in the
same way as silver screens.
