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 displays.
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 4:3
(MX819ST/TS819ST)/16:10 (MW820ST/TW820ST) 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
