'''VESA''' ({{IPAc-en|ˈ|v|iː|s|ə}}), formally known as '''Video Electronics Standards Association''', is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989<ref name="CA SOS VESA Entity Detail">{{cite web |title=Business Entity Detail: Video Electronics Standards Association |url=http://kepler.sos.ca.gov |author=California Secretary of State |author-link=Secretary of State of California |id=Entity Number C1645094 |url-status=dead |archive-url=https://web.archive.org/web/20150315010639/http://kepler.sos.ca.gov/ |archive-date=March 15, 2015 |access-date=May 27, 2016 |df=mdy-all }}To retrieve the information, search for Entity Number C1645094.</ref> and has its office in San Jose.<ref name="CA SOS VESA Entity Detail"/><ref>{{cite web |title=Contact VESA |url=http://www.vesa.org/about-vesa/contact-vesa |author=Video Electronics Standards Association |website=VESA.org |access-date=May 27, 2016 }}</ref> It claims a membership of over 300 companies.<ref name="VESA mission">{{Cite web |last=Video Electronics Standards Association |title=Mission/Vision |url=http://www.vesa.org/about-vesa/missionvision |access-date=2020-07-16 |website=VESA.org }}</ref>

In November 1988, NEC Home Electronics announced its creation of the association to develop and promote a Super VGA computer display standard as a successor to IBM's proprietary Video Graphics Array (VGA) display standard. Super VGA enabled graphics display resolutions up to 800×600 pixels, compared to VGA's maximum resolution of 640×480 pixels—a 56% increase.<ref name="InfoWorld 1988-11-14">{{cite news |title=NEC Forms Video Standards Group |first=Mark |last=Brownstein |work=InfoWorld |issn=0199-6649 |date=November 14, 1988 |volume=10 |issue=46 |page=3 |access-date=May 27, 2016 |url=https://books.google.com/books?id=wTsEAAAAMBAJ&pg=PT2 }}</ref>

The organization has since issued several additional standards related to computer video displays. Widely used VESA standards include DisplayHDR, DisplayPort, and Flat Display Mounting Interface.

== Standards == * Feature connector (VFC), obsolete connector that was often present on older videocards, used as an 8-bit video bus to other devices * VESA Advanced Feature Connector (VAFC), newer version of the VFC that widens the bus to either a 16-bit or 32-bit bus * VESA Local Bus (VLB), once used as a fast video bus (akin to the more recent Accelerated Graphics Port (AGP)) * VESA BIOS Extensions (VBE), used for enabling standard support for advanced video modes<ref name="byte_12_1990_vga_to_the_max">{{Cite magazine |date=December 1990 |title=VGA to the max |magazine=BYTE |last=Kliewer |first=Bradley Dyck |url=https://archive.org/details/byte-magazine-1990-12/page/n403/mode/2up |access-date=2026-01-06 |pages=355-360 |volume=15 |issue=13 |issn=0360-5280}}</ref> * Display Data Channel (DDC), a data link protocol which a host device can use to control an attached display and communicate EDID, DPMS, MCCS and similar messages * Extended Display Identification Data (EDID), a data format for display identification data * Monitor Control Command Set (MCCS), a message protocol for controlling display parameters such as brightness, contrast, display orientation from the host device * DisplayID, display identification data format, which is a replacement for E-EDID * VESA Display Power Management Signaling (DPMS), which can be used to invoke power saving modes in monitors * Digital Packet Video Link (DPVL), a display link standard that can be used to update only portions of the screen * VESA Stereo, a standard 3-pin connector for synchronization of stereoscopic images with LC shutter glasses * Flat Display Mounting Interface (FDMI) * Generalized Timing Formula (GTF), video timing standard * Coordinated Video Timings (CVT), a replacement for GTF * VESA Video Interface Port (VIP), a digital video interface standard * DisplayPort (DP), a digital display interface standard * VESA Enhanced Video Connector, an obsolete standard for reducing the number of cables around computers * DisplayHDR, a standard to simplify HDR specifications for the display industry and consumers

== History == At the time DisplayPort was announced, VESA was criticized for developing the specification in secret and having a track record of developing unsuccessful digital interface standards, including Plug & Display and Digital Flat Panel.<ref>{{cite web |title=Commentary: Will VESA survive DisplayPort? |date=13 October 2005 |url=http://digitimes.com/displays/a20051007PR200.html }}</ref>
