Connecting to an External Computer Monitor
If you connected the projector to a computer using a Computer port, you can also connect an external
monitor to the projector. This lets you see your presentation on the external monitor even when the
projected image is not visible.
Note: Monitors that use a refresh rate less than 60 MHz may not be able to display images correctly.
1. Make sure your computer is connected to the projector's Computer port. If there are two computer
ports, make sure you use the Computer1 port.
2. Connect the external monitor's cable to your projector's Monitor Out port.

cables as necessary.
2. Locate the appropriate cable to connect your external speakers, such as a stereo mini-jack-to-pin-
jack cable, or another type of cable or adapter.
