A host device supplying, via a hub, different picture signals to first and second projectors connected to ports, respectively, of the hub, executes a correlation process to obtain port numbers of the ports connected to the projectors, respectively, and serial numbers of the projectors, with the port numbers correlated with the serial numbers; an enumeration process to enumerate first and second display devices which are abstract or virtual versions of the projectors, respectively, to obtain display device information of each of the first and second display devices, and to obtain the serial numbers of the projectors in accordance with an order in which the first and second display devices were enumerated; and an array generation process to collate the serial numbers obtained by the correlation process to the serial numbers obtained by the enumeration process to store, in array elements, the display device information in an order identical to an order of the collated serial numbers, based on a numerical order of the port numbers obtained by the correlation process. 1. A non-transitory computer-readable medium storing a program that causes a computer execute processes , the computer supplying , via a hub , different picture signals to first and second displays connected to first and second downstream ports , respectively , of the hub , the processes including:a correlation process to obtain, for each of first and second display devices, port numbers of ports connected to the first and second displays and serial numbers of the first and second displays, with the port numbers correlated with the serial numbers, each of the first and second display devices being an abstract or virtual version of the first and second displays, respectively;an enumeration process to enumerate the first and the second display devices, obtain display device information of each of the first and second display devices in accordance with an order in which the first and second display devices ...
