Screen Size and Projection Distance

The distance between the projector's lens and the screen determines the actual image size.

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.
