DVI Full Form

DVI Full Form

Edited By Team Careers360 | Updated on May 25, 2023 09:14 AM IST

What is the full form of DVI?

DVI stands for Digital Video Interference. A video display interface creates an industry standard for transmitting digital video content into digital display devices. It links a display device, such as monitor projectors, computer display monitors, flat-panel Liquid crystal displays (LCDs), and other gadgets, to the video source. Its development is done to displace the established Video graphics array (VGA ) standard.

Uncompressed digital video is transmitted over the DVI interface, which can be configured to handle a variety of modes, including DVI-D (only digital), DVI-A (just analogue), and DVI-I. (analogue and digital). Any VGA interface is compliant with this specification. And while DVI is primarily associated with computers, it is occasionally used in consumer gadgets like Digital versatile disc (DVD) players.

DVI connectors

Some types of DVI connectors are-

  • DVI-I Single link- It has three rows with six pins and two contacts in each row.

  • DVI-I Dual link- It also has three rows but each row contains eight pins and two contacts.

  • DVI-D single link- It has three rows with six pins but contacts are absent.

  • DVI D- Dual link- It has three rows with eight pins and no contacts.

  • DVI-A- It has three rows but all three rows have different numbers of pins i.e the first row has five pins, the second row has four and the last row has three pins.

Proposed DVI structures

Some proposed DVI structures are listed below-

  • IEEE 1394- It was a combined data stream but unsuitable for apps that need uncompressed HD video.

  • HDMI- It is also called High definition multimedia interface. It includes digital audio transmission.

  • UDI- It stands for unified display interference. It was disapproved later.

History of DVI

DVI was created by the DDWG (Digital Display Working Group) in 1999 to replace the analogue transmission mechanism now used by VGA with a digital transmission method.

Compared to the current VGA technology, it enabled DVI to help display hardware in developing additional colours. Better pigments were now visible on projectors, computers, and other screens.

Benefits of DVI

  1. DVI transmits digital signals, so there is no need to convert the information that is in digital form. It reduces processing and, as a result, improves transmission speed.

  1. DVI can transmit analogue and digital signals, while VGA can only convey analogue signals.

  1. Compared to VGA, it displays a noticeably superior, sharper, and more precise visual quality.

  1. The connectors support resolutions up to 1920 x 1200 pixels for single-link format and 2560 x 1600 pixels for dual-link format.

  1. Plug and Play connectors are available. Unlike VGA, there is no need to restart the system.

Demerits of DVI

  1. DVI is a more outdated technology that only allows a certain level of resolution.

  1. Overall, colour capacity is lower than that of the successors.
