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.
