Setting up
When planning the projector and screen geometry, refer to the figures below and the information on the following
pages for reference. After the projector is roughly positioned, picture size and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens shifting mechanism.
Screen size and throw distance
L (LW/LT)
Projection distance
SH
Height of the projection area
SW
Width of the projection area
H
Vertical distance between the lens centre level
and the bottom edge of the projected image.
SD
Diagonal length of the projection area
NOTE:
• All following measurements and the calculation results are approximate and may differ slightly from the actual
measurements.
• The throw ratio is based on the value during projection onto an 80-inch screen size.
• Lens shift is not available when using the ET-DLE055, and so the height position (H) is SH/2.
• See the operating instructions that is provided with the projector.
• Special care should be used when DLP projectors are used in the same room as high power laser equipment. Direct or
indirect hitting of a laser beam on to the lens can severely damage the Digital Mirror Devices™ in which case there is a
loss of warranty.
