Although the pin layout is copied from VESA EVC, the connector shell is slightly different: EVC uses a trapezoid shape, while P&D uses a D-shape. The interface is protected by patents issued to Molex .
The physical arrangement of the EVC pins is identical to the newer VESA Plug and Display (P&D), which carries digital video over the pins used in EVC to carry analog audio (input and output) and video input.

The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, HD-15or erroneously DB-15(HD). DE-15 is the accurate nomenclature under the D-sub specifications: an "E" size D-sub connector, with 15 pins in three rows.
All VGA connectors carry analog RGBHV (red, green, blue, horizontal sync, vertical sync) video signals. Modern connectors also include VESA DDCpins, for identifying attached display devices. In both its modern and original variants, VGA utilizes multiple scan rates, so attached devices such as monitors are multisyncby necessity. The VGA interface i...
The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 320×400px @70 Hz, or 320×480px @60 Hz (12.6 MHz of signal bandwidth) to 1280×1024px (SXGA) @85 Hz (160 MHz) and up to 2048×1536px (QXGA) @85 Hz (388 MHz). There are no standards defining the quality required for each resolution, but higher-quality cables typica...
Some high-end monitors and video cards used multiple BNC connectors instead of a single standard VGA connector,[which?] providing a higher quality connection with less crosstalk by utilising five separate 75 ohm coaxial cables. Within a 15-pin connector, the red, green, and blue signals (pins 1, 2, 3) cannot be shielded from each other, so crosstal...
Various adapters can be purchased to convert VGA to other connector types. One common variety is a DVI to VGA adapter, which is possible because many DVI interfaces also carry VGA-compatible analog signals. Adapting from HDMI or DisplayPortto VGA without an active converter is not possible because those connectors don't output analog signals. For c...
A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have minor ...
Digital Visual Interface (DVI) 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 ...
The Flat Display Mounting Interface ( FDMI ), also known as VESA Mounting Interface Standard ( MIS) or colloquially as VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel monitors, televisions, and other displays to stands or wall mounts.

Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
The VESA Digital Flat Panel ( DFP) interface standard specifies a video connector and digital TMDS signaling for flat-panel displays. [1] It features 20 pins and uses the PanelLink protocol; the standard is based on the preceding VESA Plug and Display (P&D) standard, ratified in 1997.
