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.

When using a 4:3 Screen

Screen size Projection distance (Wide/Tele.)

(inch) (m) (feet, inch)

60 2.4 – 2.9 7’ 10” – 9’ 6”

80 3.2 – 3.9 10’ 6” – 12’ 10”

100 4.0 – 4.9 13’ 1” – 16’

120 4.8 – 5.8 15’ 9” – 19’

150 6.1 – 7.3 20’ – 23’ 11”

200 8.1 – 9.8 26’ 7” – 32’ 2”

When using a 16:9 Screen

Screen size Projection distance (Wide/Tele.)

(inch) (m) (feet, inch)

60 2.6 – 3.2 8’ 6” – 10’ 6”

80 3.5 – 4.2 11’ 6” – 13’ 9”

100 4.4 – 5.3 14’ 5” – 17’ 5”

120 5.3 – 6.4 17’ 5” – 21’

150 6.6 – 8.0 21’ 8” – 26’ 3”

200 8.8 – 10.6 28’ 10” – 34’ 9”

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.

Adjustment Through Digital Lens Shift

Screen size Distance to top edge of screen

(inch) (cm) (inch)

60 19 – 44 7-1/2 to 17-5/16

Distance from center of projector’s lens to top

edge of screen

(See the owner’s manual for the projector.)

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)
