A power supply controlling system includes a receiving device, a power supply device, and a transmitting device connected to an information processing apparatus. The receiving device includes a transmitting portion that transmits a switch signal of a power supply switch used for on/off of the power supply device to the transmitting device via second signal lines used for the reception of a second video signal, which are different from first signal lines used for the reception of a first video signal. The transmitting device includes an acquiring portion that acquires the switch signal from the second signal lines on which the second video signal and the switch signal are mixed, and an outputting portion that outputs the switch signal to the power supply device. The receiving device and the transmitting device are connected with a single cable including the first and the second signal lines. |
