Connecting a DVI source device

The projector provides a DVI-I input socket that allows you to connect it to a DVI source device like DVD player, or a VGA output device like notebook or desktop computer.

There are three types of DVI connector: 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 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 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 a DVI-D equipment. Make sure what kind of format you need before you purchase the cable. Or you can purchase a DVI-I cable which will be more useful in any type of DVI connection situations.

Examine your source device to determine if it has an unused DVI or VGA (D-Sub) 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 through a DVI cable:

For information on connecting a DVI source device to a computer through a VGA to DVI-A cable, see "Connecting a computer" on page 22.

1.Take the 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-I signal input socket on the projector.

3.If you wish to make use the projector speakers, 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 PC Audio socket or Audio L/R sockets on the projector.

Once connected, the audio can be controlled by the remote control (Volume +/-) or projector On-Screen Display (OSD) menus. See "Volume", "Treble", "Bass", and

"Mute" on page 45 for details.

The final connection path should be like that shown in the following diagram:
