Home Theater, DVI Cable Information and Help


So What is DVI? DVI Stands for Digital Visual Interface. DVI is the digital interface standard produced by the DDWG (Digital characterize Working Group). Led by Compaq, Fujitsu, Silicon Image, Hewlette Packard, NEC, Intel and IBM, the DDWG’s main objective is to “address the industry’s requirements for a digital connectivity specification for high-performance PCs and digital displays.”

With the need to adjust to both digital and analog monitors, this new digital interface standard was produced to transform analog signals into digital signals. DVI’s High bandwidth capabilities make it ideal for HDTV connections. Also obtainable in dual link, DVI can reach higher resolutions nevertheless.

Using the pictures on the right, you can determine the kind of connection you need, be it DVI-D, or DVI-I. To determine the actual signal being used you will have to consult your manual for the device being connected. For more information concerning DVI:

DVI-D Digital. Connectors on DVI-D do not have the 4 additional pins, these are meant for carrying Digital signals only. Digital must be connected to Digital and Analog to Analog. While you can plug a DVI-D cable into a DVI-I socket, both devices you are connecting must sustain Digital signal format. Analog to Digital will not work.

DVI-I Analog or Digital. Connectors are basically the same as DVI-D with the exception of 4 additional pins. You’ll notice both have 3 rows of pins to the left, and one horizontal pin to the right. The DVI-I connection has 4 additional pins, 2 on top and 2 on bottom. These pins are used to carry the needed signals for RGBHV analog video. (Red, Green, Blue and Horizontal). You can use DVI-I on both DVI-D and Analog connections, but remember, an analog device will not be compatible with a Digital device. For more pictures of these items visit:


Adapters HD15 to DVI-I (VGA to analog) adapters exist to connect your analog device to a analog characterize by DVI connection.

Remember that while DVI-I is usable for Digital characterize, the additional 4 pins make it usable for Analog in addition. The needed adapters is obtainable in our store.
