The DVI connector on a device is given one of three names, depending on which signals it implements: To promote interoperability between DVI-D and HDMI devices, HDMI source components and displays support DVI-D signalling. For example, an HDMI display can be driven by a DVI-D source because HDMI and DVI-D both define an overlapping minimum set of supported resolutions and frame buffer formats.

One of the purposes of DVI stream encoding is to provide a DC-balanced output that reduces decoding errors. This goal is achieved by using 10-bit symbols for 8-bit or less characters and using the extra bits for the DC balancing. Digital Visual Interface ( DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content. IEEE 1394 was proposed by High-Definition Audio-Video Network Alliance ( HANA Alliance) for all cabling needs, including video, over coax or 1394 cable as a combined data stream. However, this interface does not have enough throughput to handle uncompressed HD video, so it is unsuitable for applications such as video games and interactive program guides. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics.

Retrieved 31 January 2023.In some cases, DVI can carry over audio when connected to a physical HDMI adapter. For more information about that, take a look at this article. If you have the option to use HDMI or another port liked Display Port, use those instead, DVI and VGA should only be used as a last resort because the quality isn’t the best.

DVI devices manufactured as DVI-I have support for analog connections, and are compatible with the analog VGA interface [1] by including VGA pins, while DVI-D devices are digital-only. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). [2] Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players. The maximum resolution on a DVI-D dual link is 2560×1440 at 60 Hz, the same as the DVI-I dual link resolution. Digital video pixel data is transported using multiple TMDS twisted pairs. At the electrical level, these pairs are highly resistant to electrical noise and other forms of analog distortion. DVI made its way into products starting in 1999. One of the first DVI monitors was Apple's original Cinema Display, which launched in 1999.So you can use it to connect to a secondary old monitor or TV that only has DVI or VGA inputs. The output resolution will be good enough for documents and watching movies but it won’t be true-HD and I definitely do not recommend it for games. In December 2010, Intel, AMD, and several computer and display manufacturers announced they would stop supporting DVI-I, VGA and LVDS-technologies from 2013/2015, and instead speed up adoption of DisplayPort and HDMI. [18] [19] They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity". An earlier attempt to promulgate an updated standard to the analog VGA connector was made by the Video Electronics Standards Association (VESA) in 1994 and 1995, with the Enhanced Video Connector (EVC), which was intended to consolidate cables between the computer and monitor. [3] [4] EVC used a 35-pin Molex MicroCross connector and carried analog video (input and output), analog stereo audio (input and output), and data (via USB and FireWire). At the same time, with the increasing availability of digital flat-panel displays, the priority shifted to digital video transmission, which would remove the extra analog/digital conversion steps required for VGA and EVC; [5] :5–6 the EVC connector was reused by VESA, [6] which released the P&D standard in 1997. [3] P&D offered single-link TMDS digital video with, as an option, analog video output and data (USB and FireWire), using a 35-pin MicroCross connector similar to EVC; the analog audio and video input lines from EVC were repurposed to carry digital video for P&D. [5] :4 [7] :§1.3.3 As I mentioned earlier, DVI and VGA are dying standards, but they still have some practical uses. DVI-I is good because it can support modern resolutions (1080P at 60Hz) and you can easily convert it to other connector types. Most analog connectors, such as VGA, require active adapters to convert to HDMI, but you don’t need that with DVI.

Docter, Quentin; Dulaney, Emmett; Skandier, Toby (2012). CompTIA A+ Complete Deluxe Study Guide: Exams 220-801 and 220-802. Indianapolis, Indiana: John Wiley & Sons, Inc. ISBN 978-1118324066. DVI's digital video transmission format is based on panelLink, a serial format developed by Silicon Image that utilizes a high-speed serial link called transition minimized differential signaling (TMDS). Because P&D was a physically large, expensive connector, a consortium of companies developed the DFP standard (1999), which was focused solely on digital video transmission using a 20-pin micro ribbon connector and omitted the analog video and data capabilities of P&D. [4] :3 [5] :4 DVI instead chose to strip just the data functions from P&D, using a 29-pin MicroCross connector to carry digital and analog video. [8] Critically, DVI allows dual-link TMDS signals, [9] meaning it supports higher resolutions than the single-link P&D and DFP connectors, which led to its successful adoption as an industry standard. Compatibility of DVI with P&D and DFP is accomplished typically through passive adapters that provide appropriate physical interfaces, as all three standards use the same DDC/EDID handshaking protocols and TMDS digital video signals.

Single Link and Dual Link

Thunderbolt: an interface that has the same form factor as Mini DisplayPort (in version 1 and 2) or USB-C (in version 3 and 4) but combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal, permitting the connection of PCIe devices in addition to video displays. It provides DC power as well.

However, DVI-I and DVI-D are still found on monitors and computers. I won’t be talking about DVI-A in this article because it’s rarely used today. MicroCross DVI (Digital Visual Interface) Connector System" (PDF). Molex. November 1999 . Retrieved 31 January 2023. DVI is the only widespread video standard that includes analog and digital transmission in the same connector. [13] Competing standards are exclusively digital: these include a system using low-voltage differential signaling ( LVDS), known by its proprietary names FPD-Link (flat-panel display) and FLATLINK; and its successors, the LVDS Display Interface (LDI) and OpenLDI.

Wrapping it Up

Unified Display Interface (UDI) was proposed by Intel to replace both DVI and HDMI, but was deprecated in favor of DisplayPort. Walton, Jarred (March 2, 2007). "Dell 2407WFP and 3007WFP LCD Comparison". AnandTech . Retrieved November 7, 2013. DVI-D single link has the same bandwidth as DVI-I single link, so the maximum resolution is the same at 1920×1200 at 60 Hz. Like other ways of transmitting video, there are two different regions: the active region, where pixel data is sent, and the control region, where synchronization signals are sent. The active region is encoded using transition-minimized differential signaling, where the control region is encoded with a fixed 8b/10b encoding. As the two schemes yield different 10-bit symbols, a receiver can fully differentiate between active and control regions. To make it easier to understand, most graphics cards have at least one dual-link DVI port, single-link DVI-I is kind of dated.
