•The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER-1jack.

•If you wish to use this connection method when the projector is in standby mode, make sure the Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See "Standby Settings" on page 46 for details.

Connecting video source devices

You need only connect the projector to a video source device using just one of the connecting methods, however each provides a different level of video quality. The method you choose will most likely depend upon the availability of matching terminals on both the projector and the video source device as described below:

Terminal name	Terminal appearance	Picture quality
HDMI		Best
Component Video		Better
S-Video		Good
Video		Normal

Connecting audio

The projector has built-in speaker(s) which are designed to provide basic audio functionality accompanying data presentations for business purposes only. They are not designed for, nor intended for stereo audio reproduction use as might be expected in home theater or home cinema applications.

The built-in speaker(s) will be muted when the AUDIO-OUTjack is connected.

•The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See "Connecting audio" on page 17 for details.

•If the selected video image is not displayed after the projector is turned on and the correct video source has been selected, check that the video source device is turned on and operating correctly. Also check that the signal cables have been connected correctly.

Playing sound through the projector

You can make use of the projector (mixed mono) speaker(s) in your presentations, and also connect separate amplified speakers to the AUDIO-OUTsocket of the projector.

If you have a separate sound system, you will most likely want to connect the audio output of your Video source device to that sound system, instead of to the mono audio projector.

You can also use a microphone to output the sound through the projector speaker(s).

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 45 for details.
