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 SYSTEM SETUP: BASIC > Auto Source menu is
On if you want the projector to automatically search for the signals.
To 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 picture from the selected source will appear.
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.
• 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
