DVI and HDMI Interfaces Worth Knowing

In today’s fast changing video display market connector interfaces are evolving. For many years the 15 pin high density connector (HD15) was the standard. This is in the process of changing. The HD15 interface is an interface that can only be used for analog video signal. With the advent of digital video two new interfaces are becoming popular. The first is DVI (Digital Video Interface). The DVI interface is offered in multiple versions (DVI-I, DVI-A and DVI-D) as well as single link and dual link configurations. The table below illustrates the various DVI configurations allowing easy visual identification.

Various DVI Configurations

Shown are a number of DVI connector interfaces that can be identified by the pin configurations. They include DVI-A (analog only), DVI-D (digital only) and DVI-I (analog and digital). In addition, single link and dual link configurations exist for both DVI-D and DVI-I. Shown are the major configurations illustrating the distinguishing features for each type of DVI interface.
Analog and Digital  Analog Only  Digital Only

DVI-I Single Link
Three rows of 6 pins and two contacts above and below the flat blade.		 
DVI-A
One row of 5 pins, one row of 3 pins and one row of 4 pins with two contacts above and below the flat blade.		 
DVI-D Single Link
Three rows of 6 pins and no contacts above or below the flat blade.

DVI-I Dual Link
Three rows of 8 pins and two contacts above and below the flat blade.		   
DVI-D Dual Link
Three rows of 8 pins and no contacts above or below the flat blade.
Another up and coming interface is HDMI (High Definition Multimedia Interface). The unique feature of HDMI besides its small size is the capability to carry both audio and video signals in a digital format. The matrix below shows a comparison of all the major digital video interfaces.
