VESA

From Wikipedia, the free encyclopedia

VESA (Video Electronics Standards Association) is an international standards body for computer graphics founded in the late 1980s by NEC Home Electronics and eight other video display adapter manufacturers.

Pronounced VESA - As in Mesa, AZ not as VISA.^{[citation needed]} This is a common misconception amongst many.

VESA's initial goal was to produce a standard for 800x600 SVGA resolution video displays. Since then VESA has issued a number of standards, mostly relating to the function of video peripherals in IBM PC compatible computers.

[edit] Standards

VESA 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 above VFC that widens the 8-bit bus to either a 16-bit or 32-bit bus.
VESA Local Bus (VLB), once used as a fast video bus (akin to the modern AGP).
VESA BIOS Extensions (VBE), used for enabling standard support for advanced video modes (at high resolutions and color depths)
Display Data Channel (DDC), allowing monitors to identify themselves to the video boards they're attached to. The format of the actual identification data is however called extended display identification data (EDID).
VESA Display Power Management Signaling, which allows monitors to be queried on the types of power saving modes they support
A number of standards relating to flat-panel screens, video connectors, video cable timings etc.
Digital Packet Video Link
Flat Panel Display Interface (FPDI), logical and electrical standard for flat panel display interfacing.
Flat Display Mounting Interface (FDMI), which defines "VESA mounts"
Generalized Timing Formula (GTF), video timings standard
Coordinated Video Timings (CVT), a replacement for GTF
VESA Video Interface Port (VIP), a digital video interface standard.
DisplayPort Standard, a digital video interface standard.
VESA Enhanced Video Connector - an obsolete standard for reducing the number of cables around computers.
