Screen Size And Projection Distance - Sharp PG-MB60X Setup Manual

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.
