An all-in-one information handling system holds a display in a raised forward position with a support arm rotationally coupled at a rear side of the information handling system housing and a central location of the display. Gear arms integrated in the support arm engage a gear at the display and gear mechanism at the housing to synchronize rotation of the display from the forward and raised vertical position relative to the housing to a central and lower horizontal position by lowering the support arm to a horizontal position supported by the housing upper surface as the display rotates to the horizontal position.

An equipment boom and methods of installation are provided. The equipment boom includes a base member and at least one extension slidably received by the base member. A fixing arrangement is also provided which allows for fixing the axial length of the equipment boom.
