Setting up the Screen

Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Notes
• The projector lens should be perpendicular (square-on) to the screen. If the horizontal line passing
through the lens center is not perpendicular to the screen, the image will be distorted, making viewing
difficult.
• For an optimal image, position the screen so that it is not in direct sunlight or room light. Light falling
directly on the screen washes out the colors, making viewing difficult. Close curtains and dim the lights
when setting up the screen in a sunny or bright room.
• A polarizing screen cannot be used with this projector.
Standard Setup (Front Projection)
Place the projector at the required distance from the screen
according to the desired picture size. (See page 23)

• The distance from the screen to the projector
depends on the size of the screen.
• The default setting can be used, when placing the
projector in front of the screen. If the projected
image is reversed or inverted, readjust the setting to
"Front" for "PRJ Mode" in the "Options" menu.
Audience
• Place the projector so that an imaginary horizontal
line that passes through the center of the lens is
perpendicular to the screen.
