Source-derived summary

The VESA Enhanced Video Connector (EVC) is a VESA standard that was intended to reduce the number of cables around a computer by incorporating video, audio, FireWire and USB into a single cable system, terminating in a 35-pin Molex MicroCross connector. The intent was to make the monitor the central point of connection. The EVC physical standard was ratified in November 1994, and the pinout and signaling standard followed one year later.

History

The Video Electronic Standards Association (VESA) began working on a successor to the VGA connector for analog video and released the EVC physical standard in November 1994, followed by a pinout and signal standard in November 1995. After the P&D standard was released in June 1997, revisions to the EVC standards were issued in November 1997.

EVC was used for few products, perhaps most commonly found on the HP9000 B/C/J-class workstations introduced in 1997. Although EVC did not find favour with computer manufacturers, it evolved into the somewhat more popular VESA Plug and Display (P&D) standard using a physically identical 35-pin interface with a different shell, capable of transmitting video (both analog and digital) and data. Digital Visual Interface (DVI, 1999), essentially a modified version of P&D stripped of the data signals with higher maximum resolution by adding a second, three-pair digital video channel, would become the industry standard for digital video connections and achieved widespread implementation.

Technical

A VESA EVC connector is capable of carrying analog video (VGA-based) output, video input (composite or S-video), FireWire, analog stereo audio (input and output), and USB signals. Analog video is carried by the C1–C4 pins surrounding the C5 crossed ground plane; this was a development of the 13W3 connector, which was typically fitted to high-end workstations and had three miniature coaxial terminals embedded in the connector.

Editorial summary

Begin with the source’s own compact description: “VESA Enhanced Video Connector” is interface standard for displays and peripherals. The dossier treats that line as a proposition to test through VESA, Enhanced and Video, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1994, 1995, 1997, 1999—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, VESA, Enhanced and Video is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “interface standard for displays and peripherals” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q4006940. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1994, 1995, 1997 and 1999.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
