A tablet mounting system may include a display having a perimeter edge surrounding a front face and a rear face, the front face having a transverse width and having a display region. An elongate opening may extend into the front face and spaced from the perimeter edge of the display to receive and facilitate mounting of a display support accessory. The elongate noncircular opening transversely extends along the front face from a first side of a transverse midpoint to a second opposite side of the transverse midpoint of the front face.
