Abstract
An information processing device includes: a convertor that executes a control program to convert an input video signal, and, when having received a first notification querying for a connection state of the first display device and having detected a resistance value corresponding to a state where a first display device is connected on a path connected with the first display device, transmits a second notification; a display controller that transmits the first notification to the convertor when having received an instruction to update the control program, and updates the control program when having received the second notification as a response to the first notification; and a resistance changer that connects a dummy resistor to the path and causes the path to have the resistance value corresponding to the state when the resistance value corresponding to the state is not detected on the path.
