Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4 : 3
minimum
maximum
Aspect ratio 16 : 9
minimum
maximum
Installable angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector
may be installed
at a vertical
angle of ±30°.

NOTE: Distances calculated with the above equations will include a slight error.
• Horizontal direction
The projector may be installed at a horizontal angle of ±10°.
PT-LB1
unit : mm (inch)
L: Distance to screen
H: Height from the edge of screen to
center of lens
NOTE:
Illustrations show the projector installed
using optional ceiling bracket.
This illustration is not drawn to scale.
* This distance is especially recommend-
ed for ceiling-mounted use and other
permanent installations.
NOTE:
Values shown are approximate.
The value for L (distance to screen)
varies slightly depending on the zoom
lens characteristics.
When the shortest projection distance is
used, a small amount of distortion may
occur in the image due to the zoom lens
characteristics.
