Abstract
A display apparatus includes a plurality of connectors including a first connector and a second connector, a power supply, a display panel, and circuitry. Each of the plurality of connectors is connectable with one of a plurality of external devices including a first external device and a second external device. The circuitry is to detect that one of the plurality of external devices is connected to one of the plurality of connectors, perform negotiation on electric power with the external device that is detected, and control the power supply to output, based on a result of the negotiation, electric power to be used by the external device that is detected from the connector. In a case that the circuitry detects that the first external device is connected to the first connector and the second external device is connected to the second connector, the circuitry is further to control the power supply to output electric power, input from the first connector connected to the first external device, from the second connector to the second external device. In a case that the electric power to be output from the second connector is determined to be smaller in amount than the electric power t…
