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.
