* VESA Feature Connector ( VFC ), obsolete connector that was often present on older videocards, used as an 8-bit video bus to other devices

The Feature connector was an internal connector found mostly in some older VESA Local Bus, ISA and PCI graphics cards, but also on some early AGP ones.

USB signals are not incorporated into the connector, but were earlier incorporated into the VESA Plug and Display connector used by InFocus on their projector systems, and in the Apple Display Connector, which was used by Apple until 2005.

M1-DA connectors are sometimes labeled as DVI-M1 ; they are used for the VESA Enhanced Video Connector and VESA Plug and Display schemes.

* VESA Enhanced Video Connector, an obsolete standard for reducing the number of cables around computers.

* VESA Local Bus ( VLB ), once used as a fast video bus ( akin to the more recent AGP )

* VESA BIOS Extensions ( VBE ), used for enabling standard support for advanced video modes ( at high resolutions and color depths )

* VESA Display Power Management Signaling ( DPMS ), which allows monitors to be queried on the types of power saving modes they support

* Flat Display Mounting Interface ( FDMI ), which defines " VESA mounts "

* VESA Video Interface Port ( VIP ), a digital video interface standard

VESA Display Power Management Signaling ( or DPMS ) is a standard from the VESA consortium for managing the power supply of video monitors for computers through the graphics card e. g. ; shut off the monitor after the computer has been unused for some time ( idle ), to save power.

In the event, the new EISA bus was itself a commercial failure beyond the high end: By the time the cost of implementing EISA was reduced to the extent that it would be implemented in most desktop PCs, the much cheaper VESA Local Bus had removed most of the need for it in desktop PCs ( though it remained common in servers due to for example the possibility of data corruption on hard disk drives attached to VLB controllers ), and Intel's PCI bus was just around the corner.

The closest to an " official " definition was in the VBE extensions defined by the Video Electronics Standards Association ( VESA ), an open consortium set up to promote interoperability and define standards.

Though Super VGA cards appeared in the same year as VGA ( 1987 ), it wasn't until 1989 that a standard for programming Super VGA modes was defined by VESA.

Enhanced Graphics Adapter ( EGA ) and better adapters natively support text modes beyond 80 × 25 character cells: 80 × 43 ( EGA ), 80 × 50 ( Video Graphics Array, VGA ), 132 × 50 and 132 × 60 ( VESA compatible Super VGA ), etc., increasing the simulated graphic resolution available, doubled again through the half block characters.

Graphics emulation includes text mode, Hercules, CGA ( including some composite modes and the 160x100x16 tweaked modes ), Tandy, EGA, VGA ( including Mode X and other tweaks ), VESA, and full S3 Trio 64 emulation.

BootSkin uses a boot-time device driver ( vidstub. sys ) to access the display directly using VESA BIOS Extensions ( VBE ), unlike other bootscreen changers which alter the boot screen image inside the kernel.

* Recommended-Pentium 90 MHz or better, 16 Mb RAM, VESA Local Bus ( VLC ) or PCI video card with fast DOS access & 1Mb of video memory, VESA 2. 0 Compliant Video card ( or software driver ), 4X speed CD-ROM and speed compensating joystick

Windows Vista and newer versions can make use of the VESA BIOS Extension support of newer graphics hardware to show their splash screen in a higher resolution than VGA allows.

VESA BIOS Extensions ( VBE ) is a VESA standard, currently at version 3, that defines the interface that can be used by software to access compliant video boards at high resolutions and bit depths.

DDC version 3, December 1997, introduced the DDC2Bi protocol and support for VESA Plug and Display and Flat Panel Display Interface on separate device addresses, requiring them to comply with EDID 2. 0.

This version had a slightly bowed back and lacked the VESA Flat Display Mounting Interface of the earlier iMac G5s.

The first version, 1. 0, was approved by VESA on May 3, 2006.

By the time there was a strong market need for a bus of these speeds and capabilities, the VESA Local Bus and later PCI filled this niche and EISA vanished into obscurity.

The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of ISA plus one VESA Local Bus as the bus configuration.

VESA ( Video Electronics Standards Association ) Local Bus worked alongside the ISA bus ; it acted as a high-speed conduit for memory-mapped I / O and DMA, while the ISA bus handled interrupts and port-mapped I / O.

The VESA Local Bus relied heavily on the Intel 80486 CPU's memory bus design.

When the Pentium processor arrived there were major differences in its bus design, and was not easily adaptable to a VESA Local Bus implementation.

This was a result of VESA Local Bus being a direct branch of the 80486 memory bus.

* VESA Local Bus, a local bus based on the Intel 80486 CPU

Compaq ) and then the VESA Local Bus Standard, were late 1980s expansion buses that were tied but not exclusive to the 80386 and 80486 CPU bus.

VESA Local Bus is an example of a local bus design.

The PC clone market did not want to pay royalties to IBM in order to use this new technology, and for desktop machines vendors of PC-compatibles stayed largely with the 16-bit AT bus, ( embraced and renamed as ISA to avoid IBM's " AT " trademark ) and manual configuration, although the VESA Local Bus was briefly popular for Intel ' 486 machines.

Older ones were based on the 16-bit ISA bus or the transitional 32-bit VESA and EISA buses.

This is the case, for instance, with the VESA Local Bus which lacks the two least significant bits, limiting this bus to aligned 32-bit transfers.

* Glueless PCI 2. 1 bus interface and VESA VL-Bus ( 325 ) interface

Their speeds often far exceeded the speed of normal ISA or even early PCI buses, e. g. 40 MByte / s for a standard ISA-based SVGA, up to 150 MByte / s for a PCI or VESA-based one, while the standard 16 bit ISA bus ran at ~ 5. 3 MByte / s and the VESA bus at up to 160 MByte / s bandwidth.

However most still had either PCI or VLB slots alongside the still-ubiquitous ISA slots, and so-called " VIP " ( VESA / ISA / PCI ) boards with all three slot types were also produced.

These kits only worked with CRT computer displays and employed either VGA pass-through, VESA Stereo or proprietary interface for left – right synchronization.

A synchronization signal is generated for LC shutter glasses worn by the viewer, using either a standard VESA Stereo plug to connect wired glasses or wireless emitters, or brief flashes of light on the viewing screen during the blanking interval.
