Setting up the Projector (Continued)
Picture (Screen) Size and Projection Distance
The projection screen size varies according to the distance from the lens of the projec- tor to the screen. Install the projector so that projected images are projected onto the screen at the optimum size by referring to the table below. Use the values in the table as a reference when installing the projector.
