Note:
A 5-percent tolerance exists between these numbers due to the difference among optical components. BenQ recommends that
if you intend to permanently install the projector, you should physically test the projection size and distance using the actual
projector in situ before you permanently install it, so as to make allowance for this projector's optical characteristics. This will
help you determine the 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.
