VESA (Template:IPAc-en), 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">Template:Cite webTo retrieve the information, search for Entity Number C1645094.</ref> and has its office in San Jose.<ref name="CA SOS VESA Entity Detail"/><ref>Template:Cite web</ref> It claims a membership of over 300 companies.<ref name="VESA mission">Template:Cite web</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">Template:Cite news</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
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>Template:Cite web</ref>
