Installation
Projection dimensions
• The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio
• *The vertical offset value is the vertical distance from the bottom edge of the image (when
the projector is on a table, diagram on the left), or top edge of the image (when the
projector is ceiling mounted, diagram on the right) to the centerline of lens.
• Due to the lens optical characteristics, every projector has its vertical offset ratio. The
vertical offset value normally gets larger while the projection distance increases.
• All measurements are approximate and may vary from the actual sizes.
• 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 your projection quality, we suggest doing the projection by following the values
in the non-gray cells.
• The values in the gray cells are for reference only.
