The VESA (Video Electronics Standards Association) interface is the distance between the four mounting holes on the back of a TV (shown as 'horizontal distance x vertical distance').
This interface is commonly used to mount screens on wall mounts or stands.
Generally speaking:
Measuring the distance between the (four) horizontal and vertical holes on the back of your TV is the fastest and easiest way to find the VESA size for your TV.
The first distance stated for a VESA interface is always the horizontal distance. The second distance is the vertical distance between the holes.
These two measurements produce the following format: HORIZONTAL x VERTICAL = VESA interface pattern.
