*When you do not operate source selection, the projector will assume the input selection condition that was previously used.

*See "Auto Source" on Page E-49 for information about the Auto Source on and off conditions.

*When the input format has been switched, you may be required to reconnect the input signal.

A press of the AUTO button starts the automatic adjustment.

Note

*If the display position is shifted, vertical lines appear on the picture, or the projection is not good even after using automatic adjustment, please perform image adjustment manually. See "Picture Adj. / Fine Picture / H Position / V Position " on Page E-42.

*If the position is off or there are dark vertical bands on the picture, press the AUTO button with the screen as bright as possible (make the screen as bright as possible by for example displaying the trash window over the entire screen). If the problem per- sists after pressing the AUTO button several times, set manually at the “Picture Ad- justment” menu.
