On an electronic device which includes a display device comprising a display driving circuit, a processor, and a memory a method for changing a refresh rate of the display device includes: changing at least one of a first parameter, a second parameter, or a third parameter in response to identifying the occurrence of at least one of a scan rate change request or a change in scan rate change restriction, and applying the changed parameter among the first parameter, the second parameter, and the third parameter. The first parameter is the frequency of a first synchronization signal generated in the display driving circuit, the second parameter is the increase or decrease in a blank area to substitute for a portion of active video area in frame information, and the third parameter is the frequency of a second synchronization signal for rendering.
