PROBLEM TO BE SOLVED: To provide a display system that eliminates the need of notification of failure information between display devices to facilitate recovery from a failure state.SOLUTION: When failure of a circuit from a server 110 has not occurred, a second display device 170A and a second display device 170B make a second port in an interrupted state incapable of transmitting/receiving data and acquire data from a first port, and when failure of the circuit from the server 110 has occurred, make the second port in a transmission state capable of transmitting/receiving data, acquire data from at least one of the first port and second port, and perform display on the basis of the acquired data.SELECTED DRAWING: Figure 3 |
