A mounting system for an interface such as a flat panel display such as a computer monitor or television allows the display to be pivoted about a virtual pivot axis which passes through a center of gravity of the display. The system includes a support which is connected directly or indirectly to a support surface and a mount which is connected to a back side of the display. The support and the mount are slidable with respect to one another through an arc which has the virtual pivot axis as its center.
