Digital Visual Interface
                            DVI
What is DVI:
  •   Digital Visual Interface
  •   Supports digital and analog in a single connector
  •   The purpose is to provide an industry specification for high-
      speed digital interfaces between a PC and a display device that
      is display technology independent
  •   The end user will be able to simply plug the display monitor to
      the computer using the DVI connector system regardless of
      display technology
  •   The Digital Display Working Group (DDWG) “Promoters” are
      Intel, Compaq, Fujitsu, HP, IBM, NEC and Silicon Image, and
      are the creators of the DVI spec
  •   The Promoters intend to make avail
                           DVI
Applications:
   • Next Generation High-Resolution Video
     Applications
      –   Set-Top Boxes
      –   High-End TV/Monitors
      –   Video Graphics Applications
      –   Workstations
      –   Personal Computers
      –   Retail Business Equipment
                              DVI
Features & Benefits:
   •   Meets the requirements of all facets of the PC industry, allowing
       the adoption of a single monitor interface specification
   •   Bridges the transition from analog to digital video display
       designs
   •   Supports analog and digital interfaces which allow the end user
       to connect the display with the DVI connector equipment
       regardless of display technology
   •   Plug and play connectivity for ease of use
   •   Serial digital data transmission for reduced EMI and reduced
       crosstalk
   •   Dielectric properties control ensure no inter-pair skew issues
                      DVI
Trends & Market Drivers:

   • High resolution graphics
   • DVI will replace standard VGA Connector as
     digital monitor prices decline
                       DVI
