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.

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.
How to Convert DVI to HDMI
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. Manchester, Gary (October 7, 1996). "Molex PnD intellectual property letter" (PDF). Archived from the original (PDF) on February 22, 2003. 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.
Some DVD players, HDTV sets, and video projectors have DVI connectors that transmit an encrypted signal for copy protection using the High-bandwidth Digital Content Protection (HDCP) protocol. Computers can be connected to HDTV sets over DVI, but the graphics card must support HDCP to play content protected by digital rights management (DRM).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. The DVI specification includes signaling for reducing power consumption. Similar to the analog VESA display power management signaling (DPMS) standard, a connected device can turn a monitor off when the connected device is powered down, or programmatically if the display controller of the device supports it. Devices with this capability can also attain Energy Star certification. MicroCross DVI (Digital Visual Interface) Connector System" (PDF). Molex. November 1999 . Retrieved 31 January 2023. VGA (Video Graphics Array) is a hardware specification for display monitors and computers that allows a computer to display applications on a VGA-based monitor via a VGA cable. VGA technology is one of the oldest forms of display hardware in computing and is outfitted in virtually every computer system in the world. VGA uses analog signals but is compatible with most digital devices. While DVI technology has superseded VGA technology, both specifications are often included in personal computers, with VGA technology being much more common in laptop computers than desktop computers.
The DVI connector on a device is given one of three names, depending on which signals it implements:
How to Convert DVI to VGA
DVI (Digital Visual Interface) is a hardware specification for computers and display equipment that is similar to VGA. DVI-D (Digital Visual Interface Digital) refers to DVI technology that is used exclusively with digital devices, while other versions of DVI can be used with analog devices. While VGA technology was made for analog computers, DVI technology is more modern and is intended for digital computers and display equipment, such as monitors and projectors. While VGA and DVI produce similar quality on regular monitors, DVI produces much higher picture quality on LCD monitors and other high-definition equipment.

December 2000 . Retrieved 31 January 2023. DisplayPort (a license-free standard proposed by VESA to succeed DVI that has optional DRM mechanisms) / Mini DisplayPort 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.
Wrapping it Up
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). To ensure a basic level of interoperability, DVI compliant devices are required to support one baseline display mode, "low pixel format" (640×480 at 60Hz). The maximum resolution on a DVI-D dual link is 2560×1440 at 60 Hz, the same as the DVI-I dual link resolution. 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.
