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 57 for the center of lens dimensions of this projector before calculating the appropriate position.

For example, if you are using an 120-inch screen, the recommended projection distance is 4400 mm and the vertical offset is 91 mm.

If your measured projection distance is 6.0 m (6000 mm), the closest match in the "Distance from screen (mm)" column is 5500 mm. Looking across this row shows that a 150'' (about 3.8 m) screen is required.
