Difference between DVI and DVI-D

There are a few different types of DVI connectors, but the two most common are DVI-D and DVI-I. They look very similar, but they have different purposes. In this blog post, we’ll take a look at the difference between DVI-D and DVI-I connectors, and explain which one you should use for your needs.

What is DVI?

DVI is the digital video interface standard that was developed by the Digital Display Working Group (DDWG). The DVI standard specifies a digital interface for transmitting uncompressed digital video data to a display. DVI is commonly used on personal computers and laptops, as well as on TVs and monitors. DVI uses a DVI connector to connect to a DVI-compliant device. DVI connectors come in three different types: DVI-I, DVI-D, and DVI-A. DVI-I connectors are compatible with both digital and analog signals, while DVI-D connectors are only compatible with digital signals.

What is DVI-D?

DVI-D is a digital video interface that is used to connect a source of digital video (usually from a personal computer) to a display device such as a monitor or projector. It uses a cable with 24 pins and is capable of carrying a digital video signal at resolutions up to 1080p. DVI-D is the most common type of DVI connector and is also compatible with HDMI cables.

Difference between DVI and DVI-D

  • DVI (Digital Visual Interface) is a video interface standard that is used to connect computers and other devices to displays and monitors. DVI-D is a subset of the DVI standard that uses digital signaling to transmit video data. DVI-D connectors are typically used with DVI-equipped devices such as computers, DVD players, and DVRs. DVI-D cables are also used to carry HDCP (High-bandwidth Digital Content Protection) signals. DVI signals can be transmitted over long distances using DVI extenders. DVI switches can be used to route DVI signals from multiple sources to a single display. DVI splitters can be used to send a single DVI signal to multiple displays.
  • The main difference between DVI and DVI-D is that DVI supports both digital and analog signaling while DVI-D only supports digital signaling. This means that DVI can be used with both digital and analog displays while DVI-D can only be used with digital displays. Another difference between DVI and DVI-D is that DVI has a higher maximum resolution than DVI-D.


In order to understand the difference between DVI and DVI-D, it is important to first understand what each of these connectors is. DVI stands for Digital Visual Interface, while DVI-D stands for Digital Visual Interface – Dual Link. The main difference between these two types of connectors is that a single link DVI connector can only support up to 1920×1200 resolution at 60Hz, while a dual-link DVI connector can support up to 2560×1600 resolution at 60Hz. If you are looking for a connector that can support higher resolutions, then you will need to use a dual-link DVI-D connector.
