DVI Video Cables - (Digital Visual Interface)
DVI, short for Digital Visual Interface, has been developed primarily
for high-performance digital displays such as digital LCD monitors.
DVI handles bandwidths in excess of 160 MHz, used with UXGA and HDTV,
and can support higher resolutions with the use of a dual set of links
(Dual Link Cables), which allows resolutions over 1280 x 1024 pixels.
Dual Link vs Single Link DVI Cables
Dual Link cables support a higher bandwidth than Single Link cables,
and are fully backwards compatible, therefore Dual Link cables will
work in all Single Link applications.
DVI-I Connector
DVI-I equipment will support both analog (VGA) and digital (DVI) signals.
If you are connecting two DVI-I devices, you can either use a DVI-I
cable or a DVI-D cable. If you are connecting a DVI-I input/output
to a VGA (HD15) input/output, you must use a DVI-A
to HD15 cable.
DVI-D Connector
Equipment with a DVI-D connector only supports a digital signal. Your
only choice in cables is a DVI-D to DVI-D cable.
If you want to connect a DVI-D input/output to a VGA (HD15) input/output,
you will have to use an external video converter
which will translate the single in the direction you require.
DVI-A Connector
You will never find a DVI-A female connector on any equipment. DVI-A
is only used on male ended cables and used in analog (VGA) to DVI
applications.
DVI Cable Length Limitations
Typically, the maximum distance you can extend a DVI cable is 15 feet over a
copper cable. Infinite Cables has developed DVI cables that can extend up to 50ft at a maxium resolution of 2560×1600 (higher than the current standard) without the need of a single booster. To travel DVI over longer distances, you will need to
either use a DVI extender or booster.
