Screen Size and Projection Distance

The distance from the lens to the screen determines the actual image size. The recommended distance and projection distance values given below are for when the projector is fitted with a standard lens or an optional wide zoom lens. If the projector has been fitted with an optional lens, refer to the documentation provided with the lens.

Recommended distance

77–1113 cm (2.5–36.5 ft.)

 

 

While referring to the following table, position the projector so that the images are projected onto the screen at the optimum size. The values should be used as a guide for setting up the projector. The actual values will vary depending on projection conditions and the zoom setting.
