Positioning your projector 17

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.

Projection dimensions

Refer to "Dimensions" on page 62 for the center of lens dimensions of this projector

before calculating the appropriate position.

MX666

The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio

For example, if you are using an 120-inch screen, the recommended projection distance is

4246 mm and the vertical offset is 137 mm.

If your measured projection distance is 5.5 m (5500 mm), the closest match in the

"Projection distance (mm)" column is 5485 mm. Looking across this row shows that a 155''

(about 3.9 m) screen is required.
