You
can adjust the sharpness of the projected image using the focus
buttons.

minutes after turning on the projector before setting the focus,
zoom, and lens shift for maximum accuracy. If you
installed any of the following lenses, see the link below on
focusing with a short throw lens instead: ELPLX01S, ELPLX01WS, ELPLX02S, ELPLX02WS, ELPLU03S, or
ELPLU04.
