DVI Cables - Fundamentals - Tutorial

 Definition:
 DVI, the Digital Video Interface standard is a new form of video interface technology made to maximize the quality of flat panel LCD monitors and high-end video graphics cards. DVI is  becoming increasingly popular with video card manufacturers, and most cards purchased include both VGA and DVI output ports. In addition to being a ncomputer interface, DVI is  also used as the digital transfer method of choice for HDTV, EDTV, Plasma Display, and other ultra-high-end video displays for TV, movies, and DVDs.

DVI Variations:

1. DVI-D (Digital) format is used for direct digital connections between source video  (namely, video cards) and digital LCD monitors. This provides a faster, higher-quality image than with analog, due to the nature of the digital format DVI-D eliminates the  analog conversion process and improves the connection between source and display.

2. DVI-A (Analog) format is used to carry a DVI signal to an analog display, such as  a CRT monitor or an HDTV. Although some signal quality is lost from the digital to analog conversion, it still transmits a higher quality picture than standard VGA.

 3. DVI-I format is an integrated system capable of  transmitting either a digital-to-digital signal or an  analog-to-analog signal, but it will not work transmitting  a digital-to-analog or analog-to-digital signal.

Single and Dual Links
The Digital formats are available in DVI-D Single-Link and Dual-Link as well as DVI-I  Single-Link and Dual-Link format connectors. The dual links provide an increase of speed and signal quality;

 Choosing The right DVI Cable:
 Determining which type of cable to use for your DVI products is critical in getting the right product the first time. Check both of  the female DVI plugs to determine what signals they  are compatible  with. Be sure to look for a label, or check the product documentation to make sure you know what type it is. If you have plugs that are DVI-D, they will accept a  DVI-D  cable. If you have plugs that are DVI-A, they will accept a DVI-A cable. If you have plugs that are DVI-I, they will accept any type of DVI cable.

DVI Extension Cables
It is possible to extend existing DVI cables by the use of DVI-I extension and DVI-D  Extension cables. The maximum signal length, however, is 5 meters, and going beyond that may result in quality loss.
