Positioning your projector

English

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 from the screen

corresponding to between the Min. and Max. Projection Distance values in the table.

3. Decide the exact 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.

An 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.
