The screen aspect ratio is 16:10 and the projected picture is in a 16:10 aspect ratio.
a. base on an image 762 mm from the floor, if the image is lower, the min ceiling height is reduced by the
measurement.
b. Assume the thickness of projection screen(X) is 0 mm.
c. Assume the thickness of projection screen(X) is 30 mm.

The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio.
a. base on an image 762 mm from the floor, if the image is lower, the min ceiling height is reduced by the
measurement.
b. Assume the thickness of projection screen(X) is 0 mm.
c. Assume the thickness of projection screen(X) is 30 mm.
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.
