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 USB display, take a USB cable and connect the A type end 
to the USB port of the computer, and the other end to the USB B socket on the 
projector.
Important
•
Many notebooks do not turn on their external video ports when connected to 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.
Connecting a monitor
If you want to view your presentation close-up on a monitor as well as on the screen, 
you can connect the Monitor Out signal output socket on the projector to an external 
monitor with a VGA cable following the instructions below:
To connect the projector to a monitor:
1. Connect the projector to a computer as described in Connecting a computer on 
page 13.
2. Take a suitable VGA cable (only one supplied) and connect one end of the cable to 
the D-Sub input socket of the video monitor.
Or if your monitor is equipped with a DVI input socket, take a VGA to DVI-A cable
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 is made to the 
projector.
