Positioning your projector

12

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 (4:3 or 16:9).

2.

Determine the projection distance allowed in your room. Install the projector at a 
proper distance from the screen.

3.

Refer to the table of 4:3 or 16:9 Screen Size depending on your screen ratio. Locate the 
suitable value in the column of “Distance from Screen”. In the same row, you will find 
the maximum and minimum projected image sizes.

4.

Determine the preferred height of your projector.

For example, if you are using a 4:3 screen with 2.5 meters projection distance, the maximum 
image size is close to 1.91 meters diagonal.

If you place the projector above or below the screen, you have to tilt it down or up to center 
the image on the screen after turning the projector on. In these situations, some image 
distortion will occur. Use the Keystone function to correct the distortion. See page

 for 

keystone correction.
