BenQ recommends that if you intend to permanently install the projector, you should physically test the projection size and distance using the actual projector in situ before you permanently install it, so as to make allowance for this projector's optical characteristics. This will help you determine the exact mounting position so that it best suits your installation location. 16 Positioning your projector 4. Connection When connecting a signal source to the projector, be sure to: 1. Turn all equipment off before making any connections. 2. Use the correct signal cables for each source. 3. Ensure the cables are firmly inserted. In the connections shown below, some cables may not be included with the projector (see "Shipping contents" on page 8). They are commercially available from electronics stores. Connecting a computer The projector provides a VGA input socket that allows you to connect it to a laptop or desktop computer. To connect the projector to a laptop or desktop computer: 1. Take the supplied VGA cable and connect one end to the D-Sub output socket of the computer. 2. Connect the other end of the VGA cable to the D-SUB signal input socket on the projector. The final connection path should be like that shown in the following diagram: Laptop or desktop computer VGA cable Many laptops do not turn on their external video ports when connected to a projector. Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/LCD or a function key with a monitor symbol on the laptop. Press FN and the labeled function key simultaneously. Refer to your laptop’s documentation to find your laptop’s key combination. Connection 17 Connecting Video source devices You can connect your projector to various Video source devices that provide any one of the following output sockets: • 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 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 19 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. 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 an S-Video or a composite Video source device" on page 20 for how to connect the projector to an S-Video or composite Video device. 18 Connection 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 the (optional accessory) 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 socket on the projector. The final connection path should be like that shown in the following diagram: A/V device Component Video toVGA (D-Sub) adaptor cable If you connect the projector to a Digital TV (DTV) tuner, the following resolution is supported: • 480i • 480p • 576i • 576p • 720p (50/ 60 Hz) • 1080i (50/ 60 Hz) • Component Video is the only video output that delivers native 16:9 aspect ratio picture. • If the selected video picture 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. Connection 19 Connecting an S-Video or a composite Video source device Examine your Video source device to determine if it has an unused S-Video or composite Video output socket available: • If so, you can continue with this procedure. • If not, you will need to reas...
