1. A driving controller configured to determine a driving frequency and output a driving frequency signal representing the driving frequency to a host,
wherein the driving controller comprises:
a data processor configured to receive input image data from the host and generate intermediate image data based on the input image data; and
a frequency determiner configured to determine the driving frequency based on whether the intermediate image data represents a still image or a video image and output the driving frequency signal representing the driving frequency to the host,
wherein the driving frequency signal is output to the host before a data voltage corresponding to the intermediate image data is outputted to a display panel.
