The present invention relates to an assembly for rotatably mounting a display unit to a surface for movement between a first angular position adjacent the surface, a second angular position spaced from the surface and a range of third angular positions spaced from the second angular position. A first pintle secured to a first hinge mount is rotatably connected to a first hinge bracket. A first friction element secured to the first hinge bracket imparts a first resistive friction to the first pintle. A first detent mechanism secured to the first hinge bracket releasably secures the first pintle in the second angular position and imparts a second resistive friction to the first pintle when the first pintle is rotated through the range of third angular positions. The display unit rotates in a controlled manner from the first angular position to the second angular position due to a gravitational force.
