Abstract
The present invention improves the reliability of a display apparatus by suppressing the temperature rise of the display apparatus mounted on a wall. The display apparatus is provided with a wall mount switch to detect a wall mount member if the wall mount member is attached to the rear of the display apparatus. If it is detected by the wall mount switch that the display apparatus is mounted on a wall, the display power supplied to a display unit is set lower than normal by a power controller. This suppresses the temperature rise of the apparatus mounted on a wall.
