Connection
When connecting a signal source to the projector, be sure to:
1. Turn all of the equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure that the cables are firmly inserted.
Connecting to a laptop or desktop computer
A Mac adapter (an optional accessory) is needed if you are connecting to Macintosh
computers.
Many laptops 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 laptop. Press FN and the
labeled function key simultaneously. Refer to your laptop’s documentation to learn your
laptop’s key combination.
