A seatback entertainment display system for a vehicle is provided having a support member extending from a seatback frame, and an adjustment mechanism coupled to the support member, and a display device coupled to the adjustment mechanism. The support member may be a cantilever type beam or frame extending upwardly from the seatback at a position behind and adjacent to a headrest. The support member may also be a pair of rods arranged to fixedly receive the display device and movably receive the headrest. The adjustment device may include any one or more of a forward-rearward tilting mechanism, a side to side pivoting mechanism and an up-down translation mechanism. The seatback entertainment display system is adaptable to optimize a viewing angle for a rear seat occupant of the vehicle, throughout a normal adjustment range of the seat.
