Setting up

Adjusting the projection size

The size of the projected image is basically determined by the distance from the projector's lens to the screen.

screen will vary depending on the lens shift setting.

While referring to the table below, 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.

Lens shift adjustment

The lens shift dials can be used to position the image and is especially useful when using the projector in the

following locations. p.16

Hanging from the ceiling

A screen in a high location

Projector situated to the side so that the screen can be viewed sitting right in front of it Projector situated on a shelf, etc.

When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens shift correction is adjusted optically. However, for optimal image quality the lens shift function should not be used.
