The above numbers are approximate and may be slightly different from the actual measurements. Only the
recommended screen sizes are listed. If the your screen size is not in the table above, please contact your
BenQ dealer for assistance.
An examination of the table reveals that you can place the projector lens in the range from 0.99 to 10.91m
distance from the screen, which will give you a projected image from 0.75 x 0.42m to 6.1 x 3.43m.
