A mounting system for a flat panel display includes a back assembly, a pair of arm assemblies, and a mounting assembly. Back assembly can include a slide plate connected to arm assemblies allowing arm assemblies and mount assembly to be horizontally shifted without the need to remove the mount from the wall and reattach it. Arm assemblies can include substantially hollow arms having removable covers for storing wires connected to display therein. Mounting assembly can include a tilt head that provides a path of rotation about a substantially horizontal axis that extends proximate the center of gravity of the mount and a flat panel display mounted thereon, allowing for easy adjustment and rotation of display, Mounting assembly can also include a pair of brace arms each comprised of two members configured to allow mount assembly to be expanded to mount various sized displays without extending beyond the width of the display.
