This is a VESA mount for a Synergy Stand used for attaching a central, pole mounted screen.
It will attach to a VESA 75 or VESA 100 screen and will then attach to a central pole (S2-P1 or S2-P2).
The mount can be rotated through 360 degrees to allow switching between landscape and portrait mode without removing your screen. Forward and backward tilt is achieved by a hinge section directly behind the VESA plate.
All fixings and screws needed to attach the VESA mount to your screen and then to the central pole (S2-P1 or S2-P2) are included.
