A method and an apparatus for controlling a display refresh rate of a display device are provided. The control method comprises: obtaining a display parameter of current display content of the display device; determining, based on the display parameter, whether a reduction condition of a display refresh rate is met, so as to obtain a first determination result; controlling the display device to reduce the display refresh rate from a first display refresh rate to a second display refresh rate, when the first determination result indicates that the reduction condition of the display refresh rate is met. The above schemes may collect automatically the display parameter of the current display content of the display device, and determine, depending on the display parameter, whether the display refresh rate needs to be reduced. When it is determined that the display refresh rate needs to be reduced, the display refresh rate will be automatically reduced. All of the processes may be completed automatically without participation of the user. This may significantly improve flexibility of adjusting the display refresh rate.
