What Are DVI Cables And Its Types

by Danny white

DVI stands for Digital Video Interface which is used to connect the VDC (video display controller) and a monitor. It was originally invented to support an image in digital format, now it has become a popular choice to enhance the quality of videos on monitors and LCD screens. Earlier DVI cable was also used as a digital transfer method for TV for a short time but is commonly used in computers. Today, most of the video cards already come with DVI ports for high-resolution video content. DVI can transmit digital video up to 2560*1600 resolutions. 

Depending on the format they support, Digital Video Interface Cables are divided into three categories- DVI-A (Analog), DVI-D (Digital), and DVI-I (Interface). A DVI connector has a width of 37mm and consists of multiple pins. These connectors are categorized into single-link and dual-link based on data rates. Below are the three types of DVI cable connectors based on the format they support:

 

  • DVI-A: This is a rare type of DVI connector that supports an Analog format. It comes with a total of 17 pins and does not contain a dual link. A DVI-A connector can transmit a maximum of 1920*1080 resolutions. One of their important uses is that they can be used to connect old devices to new equipment. The signals supported by DVI-A are similar to that of VGA but with some changes and, to connect a VGA video card to a DVI-A monitor, you need to have VGA to DVI adapter.

 

 

  • DVI-D: This connector only supports digital video signals. It is one of the most widely used connectors and works with both DVI-D and DVI-I cables. A single-link DVI-D connector has 24 pins divided into three rows and has a maximum resolution of 1920*1080 at 4.59 Gbps and the dual-link DVI-D connector has a total of 25 pins and a maximum of 2048*1536 resolution at 9.9 Gbps.

 

 

  • DVI-I: A DVI-I cable is an integrated type of cable connector that can transmit both analog and digital video signals. But it cannot transmit analog signals into digital and vice versa. A DVI-I connector supports all types of DVI cables. A single-link DVI-I cable has 23 pins with 1600*1200 resolution at 4.95 Gbps and there are total 29 pins in dual-link DVI-I cables that support resolution up to 2048*1536 at 9.9 Gbps.
