Check that all of the cables required for projection are securely connected.
Press the [Computer1/2] button or [S-Video/Video] button on the remote control or the [Source]
button on the projector's control panel to select the images.
Turn the power on for the devices.
If the image signals are only being output to the computer's LCD monitor or to the accessory
monitor, you need to change the output to an external destination as well as the computer's own
monitor. For some computer models, when the image signals are output externally, they no longer
appear on the LCD monitor or accessory monitor.

monitor"
If the connection is made while the power is already turned on, the function [Fn] key that switches

the computer off and then back on again.
