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): In case of displaying the 16:9 picture on the whole of the 16:9 screen.
