The original VESA mount (MIS-D) consisted of four screws arranged in a square, with the horizontal and vertical distance between the screw centers being 100 mm. This is still the most commonly used configuration for desktop computer displays. A 75 mm × 75 mm layout was defined for smaller displays.
The MIS-D screw holes have an M4 thread and are typically 10 mm deep. Appropriate fasteners (typically ~10 mm long) are often supplied with the mount rather than the display, but they are also easily available from many hardware stores.
The FDMI was extended in 2006 with a collection of additional screw patterns that are more appropriate for larger TV screens.
