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 13.
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 48 for details.
