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 Quick Auto Search function in the SOURCE menu is On if you want the
projector to automatically search for the signals.
To select the source:
1. Press SOURCE on the projector or remote
control. A source selection bar appears.
2. Press
and press MODE/ENTER.
Once detected, the selected source information
will display 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.
• The brightness level of the projected image will change
accordingly when you switch between different input signals.
Data (graphic) "PC" presentations using mostly static images
are generally brighter than "Video" using mostly moving images
(movies).
• The native display resolution of this projector is in a 16:9 aspect
ratio. For best display picture results, you should select and use
an input signal which outputs at this 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
• Firewall in the PC must be switched off to allow USB Display to work.
