A TV wall mounting device includes a wall mount box with vertical supports, a display mount receiving a TV, and an extending/contracting portion between the box and the display mount. The extending/contracting portion has lower and upper arms rotatably attached to the wall mount with rear axles, a pair of linear actuators rotatably attached to the wall mount, a front portion that rises and lowers with action of the actuators, and a horizontally-swiveling portion that is raised and lowered with the front portion and is capable of rotating right-left with respect to the front portion. The display mount is attached to the horizontally-swiveling portion. Parallel operation of the linear actuators, wherein each actuator extends and retracts while keeping the same length as the other actuator, causes the display mount to go up and down. Differential operation of the actuators causes the display mount to rotate right and left.

A display device (2) includes a processor (13) that outputs drawing data and a timing controller (11) that outputs the drawing data input from the processor according to horizontal synchronization and vertical synchronization. When a still image region where drawing data has not been updated compared with a previous frame and a moving image region where drawing data has been updated compared with a previous frame are included in one frame, the processor transmits data update information, which is for specifying the position of the moving image region or a line including the moving image region, to the timing controller temporally earlier than drawing data of the line including the moving image region. The timing controller performs processing for lowering the frame rate of the still image region or processing for thinning out some of image lines of the still image region based on the data update information.
