VESA

VESA stands for Video Electronics Standards Association. It is an international non-profit trade association established in 1989 by major computer and display manufacturers to create and promote open standards for video displays. The organization coordinates the development of interfaces, mounting systems, power management, and performance specifications to ensure compatibility across devices and brands.

Among its best-known standards are the VESA Mounting Interface Standard (MIS), which defines the hole patterns used to attach displays to stands and mounts; the VESA BIOS Extensions (VBE), which defined a standardized interface to graphics hardware for early PC BIOS and operating systems; and DPMS, the Display Power Management Signaling standard for reducing monitor power usage when idle.

VESA also played a key role in the development of DisplayPort, a high-bandwidth digital display interface introduced in the mid-2000s that is widely used to connect computers to monitors and other displays. In the early 1990s, VESA introduced the VESA Local Bus (VLB), a high-speed expansion bus for IBM-compatible computers, now considered legacy technology.

Today, VESA continues to publish standards and conformance specifications, coordinate member-driven projects, and promote interoperability among display devices, graphics adapters, and related equipment. Members include manufacturers and technology companies from around the world. The organization also maintains branding and test specifications to assist manufacturers in implementing compliant products.
