DVI = Digital Visual Interface
DVI-D = DVI-Digital
DVI-A = DVI-Analog
DVI-I = DVI-Integrated (Digital & Analog)

Developed by the Digital Display Working Group (DDWG).

Contents

Comments

Analog or Digital

  • DVI-D single link (TMDS pairs 0-2 present, 3-5 may be present in the plug, but are not wired)
  • DVI-D dual link (all TMDS pairs MUST be present and wired)
  • DVI-A (analog pins only present, digital pins may be present in the plug, but are not wired)
  • DVI-I (all pins present and wired)

Connector

  • The pinout image has wrong pin count and numbers [and I don't know how to change it]. There should be 3x8 pins, numbered 1-8,9-16 and 17-24.
  • Do not mix with the Plug & Display (P&D) connector, wich looks very similay and has got 3x10 pins+5 analog.
  • The DVI-D connector has a narrower C5 pin than DVI-A/I to avoid damage to C1-4 if attempted plugged into a DVI-D socket.
  • The DVI-I is normally just used for an output or input socket, not a cable, unless its an extension cable.
