What Is a VESA VGA Monitor?
VESA is a worldwide monitoring body for a variety of computer graphics standards. They're best known for Flat Display Mounting Interfaces (FDMI), which allow monitors to attach to walls. FDMI-compliant VGA monitors are known as VESA VGA Monitors.
VESA (Video Electronics Standard Association) was founded in the late 1980s by NEC and several other monitor manufacturers. It operates primarily as a trade group to maintain common benchmarks and standards for computer video technology. VESA's other best known standard is the Display Port benchmark for mobile computers.
VESA monitors may have one of a number of mounting interfaces. The most popular by far have a pattern of holes that are either 3 inches by 3 inches or 3 inches by 4 inches. These holes are used to screw in mounts, which are then used to attach the monitor to a wall or other surface.
The VGA standard (Video Graphics Array) is a popular benchmark for computer graphics that was developed in the late 1980s. It is best known for blocky 640x480 pixel resolution and a relatively large color palate. Although VGA is not the most popular video standard anymore, it's often used for mobile devices and specialty computers in the sciences.
