[0117] According to one embodiment, if the processor (420) does not confirm the inclusion of second information indicating that at least one of the device information is a type of second external electronic device is a wearable device, it confirms that no other wearable device exists around the wearable electronic device, and can transmit a control command to at least one first external electronic device through a communication circuit (490) instructing to change the driving frequency of the display of at least one first external electronic device that transmitted the first information to the driving frequency of the display of the wearable electronic device (current driving frequency).
