A source driver, a controller, and a method for driving a source drive are provided. The source driver includes a controller configured to receive a start pulse signal, and generate and output one of a new start pulse signal if the start pulse signal is received, and an internal start pulse signal if the start pulse signal is not received, a shift register configured to receive video data, store the video data, and output the video data if the outputted start pulse signal is received by the shift register, a digital-to-analog converter (DAC) configured to convert the video data output from the shift register into an analog voltage signal, and output the analog voltage signal, and an output buffer configured to buffer the analog voltage signal output from the DAC, and output the buffered analog voltage signal.
