BenQ recommends that if you intend to permanently install the projector, you
should physically test the projection size and distance using the actual projector
before you permanently install it, so as to make allowance for this projector's optical
characteristics. This will help you determinethe exact mounting position so that it
best suits your installation location.
To optimize the projection quality, we suggest to project images in an area without
grayscale.
To avoid damaging the DLP chips, never aim a high-power laser beam into the
projectiom lens.
