DISPLAY DEVICE, SHARED DISPLAY SYSTEM, AND PROCESSOR FOR DISPLAY DEVICE

摘要

An input device receives display input for changing a display part, out of display information (P1), that is displayed on a display (30A). At least one processor causes the display to display a first display part of the display information (P1) according to the display input. The at least one processor selectively sets a synchronous mode (SYNC) or an asynchronous (ASYNC) mode, the synchronous mode being a mode in which the external device displays (30B) a second display part that is the same as the first display part, and the asynchronous mode being a mode in which the external device displays (30B) a third display part that is not dependent on the first display part. The at least one processor transmit display part information indicating the first display part to the external device in the synchronous mode and does not transmit the display part information in the asynchronous mode.
