Connecting Video source devices You can connect your projector to various Video source devices that provide any one of the following output sockets: • HDMI • Component Video • S-Video • Video (composite) You need only connect the projector to a Video source device using just one of the above 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: Best video quality The best available video connection method is HDMI. If your source device is equipped with an HDMI socket, you can enjoy uncompressed digital video quality. See "Connecting an HDMI device" on page 15 for how to connect the projector to an HDMI source device and other details. If no HDMI source is available, the next best video signal is Component video (not to be confused with composite video). Digital TV tuner and DVD players output Component video natively, so if available on your devices, this should be your connection method of choice in preference to (composite) video. See "Connecting a Component Video source device" on page 16 for how to connect the projector to a component video device. Better video quality The S-Video method provides a better quality analog video than standard composite Video. If you have both composite Video and S-Video output terminals on your Video source device, you should elect to use the S-Video option. See "Connecting an S-Video source device" on page 16 for how to connect the projector to an S-Video device. Least video quality Composite Video is an analog video and will result in a perfectly acceptable, but less than optimal result from your projector, being the least video quality of the available methods described here. See "Connecting a composite Video source device" on page 16 for how to connect the projector to a composite Video device. Connecting audio You can make use of the projector speaker in your presentations, and also connect separate amplified speakers to the Audio Out socket of the projector. The audio output is controlled by the projector Volume and Mute settings. Connecting an HDMI device You should use an HDMI cable when making connection between the projector and HDMI devices. 1. Take an HDMI cable and connect one end to the HDMI output port of the video device. 2. Connect the other end of the cable to the HDMI input port on the projector. 15
