￿Setting Up the Screen and the Projector

Selecting a Location

The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 25" measured diagonally when the projector is roughly 0.9 m (3.1’) from the wall or screen. The largest the image can be is 300" when the projector is about 7.6 m (25.0’) from the wall or screen. Use the drawing below as a guide.

H1 and H2: H1 is the height of the screen from the intersection of optical axis and screen surface, and H2 is the height of the intersection when an image is projected at right angle to the screen.

TIP:

•For the relationship between the screen size and projection distance, see the table on page 61.

•The sizes in the above table have been obtained assuming that the aspect ratio is 4:3. They may vary from the actual sizes depending on the type of the projected image.

•The Zoom lever adjusts the image size (diagonal) +/- 20%.

NOTE:

This projector can be hung from the ceiling (Ceiling mounted) with it turned up side down.

When a translucent screen is used, the projector can project an image from behind the screen (Rear).

When the projector is hung from the ceiling or projector projects an image from behind the screen, the image must be inverted vertically or horizontally. See page 43.

• When hanging the projector from the ceiling, optional brackets (part No. LV-CL12) are required.
