Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only
display one full screen at a time. When starting up, the projector automatically searches for the
available signals.
Be sure the Advanced menu - Display > Auto Source Search menu is On if you want the
projector to automatically search for the signals.
To manually select the source:
1. Press /SOURCE. A source selection bar appears.
2. Press / until your desired signal is selected and
press OK.
Once detected, the selected source information will
appear at the corner of the screen for seconds. If
there is multiple equipment connected to the
projector, repeat steps 1-2 to search for another
signal.
Though the password function is disabled, you need to keep the old password in hand should you ever need
to re-activate the password function by entering the old password.
• The brightness level of the projected image will change accordingly when you switch between different
input signals.
• For best display picture results, you should select and use an input signal which outputs at the
projector’s native resolution. Any other resolutions will be scaled by the projector depending upon the
“aspect ratio” setting, which may cause some image distortion or loss of picture clarity. See Aspect
Ratio on page 33.
