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 1.1 m (3.7’) from the wall or screen. The largest
the image can be is 300" when the projector is about 8.8 m (29.1’) from the wall or screen. Use the drawing below as
a guide.
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 46.
• When hanging the projector from the ceiling, optional brackets (part No. LV-CL11) are required.
TIP:
For the relationship between the screen size and projection distance, see the table on page 64.
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%.
