4. Connection
When connecting a signal source to the projector, be sure to:
1.
Turn all equipment off before making any connections.
2.
Use the correct signal cables for each source.
3.
Ensure the cables are firmly inserted.
In the connections shown below, some cables may not be included with the projector (see
"Shipping contents" on page 10
). They are commercially available from electronics stores.
Connecting a computer
The projector provides VGA and DVI input sockets that allow you to connect it to both
IBM® compatibles and Macintosh® computers. A Mac adapter (an optional accessory) is
needed if you are connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer (either through a VGA
cable or VGA to DVI-A cable):
The final connection path should be like that shown in the following diagram:
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 notebook's documentation to
find your notebook's key combination.
