Computing Plus Flat-Screen-Arms are supplied with a VESA Head fitting that incorporates both
75 x 75mm and 100mm x 100mm VESA standard mounting holes. We refer to this fitting as our Universal VESA Head Mounting Bracket (Un100). This VESA fitting suits the majority of flat screens with
VESA standards mounting built into their case or chassis.
The 75 x 75mm and 100 x 100mm is the distance in millimeters between the 4 mounting holes onto which the Flat Screen is mounted.
