Connection 21 Connecting Video source devices This section describes how to connect the projector to Video source devices using video cables. Video cable connections are recommended for Video presentations. You can connect your projector to various Video source devices that provide any one of the following output sockets: •DVI •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 DVI. If your source device is equipped with a DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end analog video quality. See Connecting a DVI source device on page 22 for how to connect the projector to a DVI source device and other details. If no DVI source is available, the next best video signal is Component Video (not to be confused with composite Video). Digital TV tuners and DVD players output Component Video natively, so if available on your devices, they should be your connection method of choice in preference to S-Video or (composite) Video. See Connecting a Component Video source device on page 23 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 24 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 25 for how to connect the projector to a composite Video device. Connecting Audio The projector has a built-in mono speaker which is designed to provide basic audio functionality accompanying data presentations for business purposes only. It is not designed for, nor intended for stereo audio reproduction use as might be expected in home theatre or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speaker. Downloaded From projector-manual.com BenQ Manuals
Connection 22 Connecting a DVI source device The projector provides a DVI input socket that allows you to connect it to a DVI source device like a DVD player, or a VGA output device like a notebook or desktop computer. There are three types of DVI connectors: DVI-A, DVI-D, and DVI-I. The DVI-I socket is an integrated connector which supports both formats: DVI-A, and DVI-D. DVI-A format is used to carry a DVI signal to an analog (VGA) display, or vice-versa. Although some signal quality is lost from the signal conversion, it still transmits higher picture quality than a standard VGA connection. DVI-D format is used to directly carry a digital signal to a digital display without signal conversion. The pure digital connection provides faster and higher image quality than an analog connection, due to the nature of the digital format. DVI-A and DVI-D formats are non-interchangeable. You cannot connect a DVI-A format connector to DVI-D equipment and visa-versa. Make sure you know which kind of format your equipment is fitted with before you purchase any cables. Or you can purchase a DVI-I cable which will be more useful in any type of DVI connection situation. Examine your source device to determine if it has an unused DVI output socket available: • If so, you can continue with this procedure. • If not, you will need to reassess which method you can use to connect to the device. To connect the projector to a DVI source device or a computer: For information on connecting a DVI source device to a computer through a VGA to DVI-A cable, see Connecting a computer on page 18. 1. Take a DVI (DVI-D or DVI-I) cable and connect one end to the DVI output socket of the DVI source device. 2. Connect the other end of the cable to the DVI signal input socket on the projector. 3. If you wish to make use the projector (mixed mono) speaker, take a suitable audio cable and connect one end of the cable to the audio output sockets of the video device, and the other end to the AUDIO socket of the projector. Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See Audio Settings on page 51 for details.

Connection 23 In the unlikely event that you connect the projector to a DVD player via the projector’s DVI-D input and the projected picture displays wrong colors, please change the color space to YUV. See Changing Color Space on page 31 for details. Connecting a Component Video source device Examine your Video source device to determine if it has a set of unused Component Video output sockets available: • If so, you can continue with this procedure. • If not, you will need to reassess which method you can use to connect to the device. To connect the projector to a Component Video source device: 1. Take a Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 RCA type connectors to the Component Video output sockets of the Video source device. Match the color of the plugs to the color of the sockets; green to green, blue to blue; and red to red. 2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with a D-Sub type connector) to the D-SUB/COMP. IN socket on the projector. 3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio cable and connect one end of the cable to the audio output socket of the computer, and the other end to the Audio socket of the projector. Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See Audio Settings on page 51 for details. The final connection path should be like that shown in the following diagram: • The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See Connecting Audio on page 21 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. Audio cable A/V device Component Video to VGA (D-Sub) adaptor cable Downloaded From projector-manual.com BenQ Manuals
Connection 24 Connecting an S-Video source device Examine your Video source device to determine if it has an unused S-Video output socket available: • If so, you can continue with this procedure. • If not, you will need to reassess which method you can use to connect to the device. To connect the projector to an S-Video source device: 1. Take an S-Video cable and connect one end to the S-Video output socket of the Video source device. 2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector. The final connection path should be like that shown in the following diagram: • The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See Connecting Audio on page 21 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. • If you have already made a Component Video connection between the projector and this S-Video source device using Component Video connections, you need not connect to this device using an S-Video connection as this makes an unnecessary second connection of poorer picture quality.
