What is VESA compatibility and how do I know if my monitor is compatible?

VESA (Video Electronics Standards Association) defines the standard hole pattern on the back of monitors for mounting. The most common patterns are 75×75mm (smaller monitors, 19"–22") and 100×100mm (most 24"–32" monitors). Larger displays may use 200×100 or 200×200mm. To verify: look for a square pattern of four holes on the monitor back — measure center-to-center in millimeters. Most monitors sold since 2010 are VESA compatible, but confirm before ordering.
