Guidelines for the Projector Installation Position and
Screen Size

The relationship between the projection distance and the screen size is shown below. Use these values as
guidelines for determining the installation position.

Cautions
•
The projection distance is the horizontal distance from the surface of the projector lens to the surface of the screen.
In the case of the DPX-1, the surface of the lens is recessed by approximately 4 cm (1-9/16 inch) from its exterior.
•
Although the ceiling bracket permits adjustment of the vertical angle of the projector over a range of ±15˚, a large
angle adjustment will distort the projected image somewhat. Therefore, we recommend adjusting both the angle of
the projector and the angle of the screen.

Projection distance
(See the diagram below.)
Distance from ceiling installation surface to
center of lens
PMT-L11: 20 cm (7-7/8 inch)
PMT-H15: 90 to 147 cm (35-7/16 to 57-7/8 inch)
(can be adjusted in 3 cm (1-3/16 inch) steps)
Ceiling
When “SCREEN ASPECT” is set to 16:9 in the
SETUP menu, it is possible to use the projector’s
digital shift function to adjust the distance from the
center of the projector’s lens to the top edge of the
screen. The range of adjustment is indicated at right.
Distance from the center of the
ceiling bracket to the front edge
of the projector:
approximately 20 cm (7-7/8 inch)
