Setting up your projector

Setting up the screen

Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the projection angle of the projector. (See page 11.)

•Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of the screen center.

•Do not install the screen where it is exposed to direct sunlight or lighting. Light directly reflecting on the screen makes the projected images whitish and hard to view.

Screen size and projection distance

Refer to the following table to determine the screen size and projection distance.

•For the aspect ratio setting, see page 19.

•The figures in the tables are approximate and may be slightly different from the actual measurements.

•The lens shift height and width show distances from the factory default position.

•Depending on the installation conditions, warm air that is emitted from the exhaust vents may flow into the intake vent, causing the projector to display “TEMPERATURE!!” and then stop projecting images.
