VESA, the Video Electronics Standard Association, is an international body that sets standards for computer graphics. VESA standards also relate to display devices, and the safe and proper attachment, or mounting, of such devices.
A VESA wall mount, also referred to as FDMI, or Flat Display Mounting Interface, is a device that screws or otherwise attaches to a wall and supports display devices such as plasma televisions and other flat-panel monitors. Manufacturers that produce VESA wall mounts must meet certain variant standards to be VESA compliant.
The MIS-D, or original VESAmount, includes a panel that must contain four screws in a square arrangement. These screws require a vertical and horizontal distance between them of 100 mm. MIS-D screws use an M4 thread, or ridge that wraps around the screw to form a helix shape. M4 refers to a 4-mm diameter screw head. MIS-D screw holes are 10 mm deep; 10 mm fasteners are typically included with the VESA mount. Another VESA mount variant is the MIS-D 75, which has a 75-mm layout.
Manufacturers of VESA-compliant devices can display a label verifying that they meet the appropriate standards, called the "VESA mounting compliant" logo.
