3.4 Positioning the projector
CAUTION: The position and physical securing of the projector must be sufficient to prevent it from
accidental or involuntary movement. Proper securing of the projector is the responsibility of the
installer and user. The Projector are heavy, and can cause severe damage and injuries if falling.
General guidelines
Proper positioning of the projector lessens the overall picture setup time, and ensures a better image with
fewer artifacts.
Focus and sharpness of the image can be adversely affected if the lens axis is not fully
perpendicular to the projection surface.
Using extended cable lengths may result in reduced image quality as well as loss of control
information such as EDID (Extended Display Information Data).
The following guidelines can help you determine the best physical location for the projector.
• Only install the projector on a sturdy flat surface, or in an approved rigging frame.
• Do not install the projector in a thoroughfare or another area where it is at risk of being pushed or jostled.
• Allow sufficient free space around the projector for ventilation and exhaust, as described in section 4.2
• Use the throw ratio of the installed lens as a guideline for the projector ’ s physical distance from the screen.
• Wherever possible, the projector lens surface should be positioned so that it is perfectly perpendicular to
the center of the screen.
Use the projector offset (lens shift), rather than physical angling, to correct any off-center positioning.
• Minimize the source cable length as much as possible.
DP, HDMI and DVI are short-haul interfaces using pre-assembled cables with limited cable lengths.
• Limit the use of power cable extensions wherever possible. Where physical limitations necessitate their
use, make sure that the extension cord has adequate surge protection and meets all electrical
requirements of the connection.
• Keep the projector away from equipment that emits electromagnetic energy for example, motors,
transformers and elevators.
