Connecting a computer or monitor
Connecting a computer
The projector provides two VGA input sockets that allow you to connect them to both  
IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are  
connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
1. Take the supplied VGA cable and connect one end to the D-Sub output socket of  the computer.
2. Connect the other end of the VGA cable to the 
Computer in 1 or Computer in 2 
signal input socket on the projector.
3. If you wish to use the remote paging function, take a USB cable and connect the A 
type end to the USB port of the computer, and the other end to the 
Service socket 
on the projector. See  “Using the remote mouse control” on page 14  for details.

a projector. Usually a key combo like FN + F3 or CRT/LCD key turns the 
external display on/off. Locate a function key labeled CRT/LCD or a function 
key with a monitor symbol on the notebook. Press FN and the labeled 
function key simultaneously. Refer to your notebooks documentation to find 
your notebooks key combination.

and connect the DVI end of the cable to the DVI input socket of the video monitor.
3. Connect the other end of the cable to the Monitor Out socket on the projector.Important
„The  Monitor Out  output only works when  Computer in 1 or Computer in 2
