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 or a computer (either through a DVI cable or VGA
to DVI-A cable):
Many notebooks 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/
• With a DVI (DVI-I or DVI-D) cable
• With a VGA to DVI-A cable
1.
Take the 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.
1.
Take a VGA to DVI-A cable and connect the
VGA end to the D-Sub output socket of the
computer.
2.
Connect the DVI end of the VGA to DVI-A
cable to the DVI-I 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, an the other end to the AUDIO
socket of the projector.
Once connected, the audio can be controlled by the projector volume and mute settings. See
"Mute"
and
"Volume" on page 34
for details.
