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 projector 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. When using a wide screen (16:9) and projecting 16:9 image Picture (Screen) size Diag.
