DVI (Digital Video Interface Connectors)

DVI was developed by DDWG (Digital Display Working Group) to improve analog and digital image quality in PC applications. There are three types of DVI connectors:

1. DVI-A for Analog signals.
   
2. DVI-D for Digital signals
   
3. DVI-I (Integrated) for both analog and digital signals.

The length of the cable is flexible from 5 to 25 meters. It handles bandwidth about 160MHz.This provides connection between computer and its display devices. This is used with LCD monitor not with old VGA cable. DVI gives better quality compared to the VGA.

Therefore, before buying an LCD, make sure that graphics card has DVI connector and same time also make sure that LCD has it too. Most of the LCD today has both VGA and DVI connector but there may be some which has VGA connector, to save cost.

DVI is digital solution and need no conversion, also faulty VGA cables would result in degradation of quality. Cost is low and high speed way to interconnect peripheral devices.

Applications:

1. Computer Monitors
   
2. Set Top Boxes
   
3. A/V Receivers
   
4. HDTV
   
5. Computer Video Cards
   
6. High-End DVD players
