Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the
projected image size. BenQ has provided separate tables of dimensions for both 16:9 and 4:3 screen ratios to
assist you in determining the ideal location for your projector.
1. Determine the aspect ratio of your screen, (16:9 or 4:3)?
2. Select the
Screen Size
you desire from the 16:9 ratio screen dimension table or 4:3 ratio screen dimension
table below, according to what screen type you have. Install the projector at a distance between the
Min.
and
Max.
Projection Distance
values in the table.
3. Decide the preferred height of your projector.
For example, if you are using a 16:9 screen with 80 inches diagonal, you are suggested to place your projector
within a range between 2.34m to 3.18m from the screen. The ideal height of your projector lens center will be
level with the bottom or top side of the screen.

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.
A
n examination of the table reveals that you can place the projector lens in the range from 1.08 to 11.91m
distance from the screen, which will give you a projected image from 0.82 x 0.46m to 6.64 x 3.74m full screen.
