All our touchscreen have a 75mm or a 100mm VESA (Video Electronics Standards Association) connection on the back. The VESA dimensions are a universal standard that is used by almost all television and display manufacturers.
The VESA size is the distance (in mm) between the screw holes on the back (horizontal + vertical). The VESA standard makes it possible to easily attach the touchscreen to a universal wall bracket or mounting arm. Beetronics has a wall bracket that is optionally available here.
