    摘要: An electronic apparatus is provided. The electronic apparatus includes an input/output interface connected to a source apparatus, a display, and a processor configured to, based on detecting that the source apparatus is connected through the input/output interface, receive identification information of the source apparatus from the source apparatus, and based on the received identification information of the source apparatus, control the display to display a user interface (UI) for changing a resolution, and based on receiving a user input for changing a resolution through the displayed UI, identify whether the source apparatus can transmit a content of the resolution corresponding to the user input based on the identification information of the source apparatus, and based on identifying that the source apparatus can transmit a content of the resolution corresponding to the user input, transmit a signal requesting the content of the resolution corresponding to the user input to the source apparatus.

    摘要: A display apparatus includes a plurality of surfaces, and a display device provided on at least one surface among the plurality of surfaces. A plurality of communication sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces and configured to perform communication within a predetermined distance, each of the plurality of communication sections including different identification information. A control section is configured to perform control of the plurality of communication sections and the display device. When another display apparatus is connected to the display apparatus, the control section periodically performs time synchronization to synchronize an image displayed on the display device with an image displayed on a display device provided in the other display apparatus.
