Setting Up the Projector 25
Connecting an RGB Video Source
Follow these instructions to connect the projector to a video player or
satellite receiver that has an RGB video output port using the VGA
computer cable that came with the projector.
Before starting, make sure the projector and your DVD player or
other video source are turned off.
1. Connect one end of the VGA computer cable to the
Computer1/Component Video1 or the
Computer2/Component Video2 port on the projector.
2. Connect the other end to the video port on your player.
3. To play sound through the projector, follow the instructions
beginning on page 27.
If you don’t need to make any other connections, you can plug in
your projector and turn it on. See page 30 for instructions.
If more than one device is connected to the projector, select
Computer 1 (RGB) or Computer 2 (RGB) as the source, depending
on which port you used. See page 32 for details.
