Flat Display Mounting Interface
The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel monitors, TVs, and other displays to stands or wall mounts. It is implemented on most modern flat-panel monitors and TVs.
As well as being used for mounting monitors, the standards can be used to attach a small PC to the mount or function as a monitor mount.
The first standard in this family was introduced in 1997 and was originally called Flat Panel Monitor Physical Mounting Interface (FPMPMI), it corresponds to part D of the current standard.
Most sizes of VESA mount have four screw-holes arranged in a square on the mount, with matching tapped holes on the device. The horizontal and vertical distance between the screw centers was originally 100 mm. A 75 mm × 75 mm layout was defined for smaller displays. Later, variants were added for screens with as small as a 4-inch diagonal.
The FDMI was extended in 2006 with additional screw patterns that are more appropriate for larger TV screens. Thus the standard now specifies 7 sizes, each with more than one variant. These are referenced as parts B to F of the standard or with official abbreviations, usually prefixed by the word "VESA".
Unofficially, the variants are sometimes referenced as just "VESA" followed by the pattern size in mm, which is slightly ambiguous for the names "VESA 50" (4 possibilities), "VESA 75" (2 possibilities) and "VESA 200" (3 possibilities). However, if "VESA 100" is accepted as meaning the original variant ("VESA MIS-D, 100"), then all but "VESA MIS-E" and "VESA MIS-F, 200" have at least one unique dimension that can be used in this way, as can be seen from the tables below.

More details can be found by purchasing a copy of the standard itself, including rules to ensure cables don't prevent using the mounts.

In practice, many screens that almost comply with part F of the standard deviate in various minor ways, and most brands of compliant brackets are designed to handle these deviations with little or no trouble for the end user:
Manufacturers of FDMI compliant devices can license the use of a hexagonal "VESA mounting compliant" logo.
