Display apparatus and control method thereof
First Claim
1. A display apparatus used for a video wall formed by a plurality of display apparatuses that are sequentially connected to one another, the display apparatus comprising:
- a communicator comprising an output port to which a first display apparatus of the plurality of display apparatuses is connectable and an input port to which a second display apparatus of the plurality of display apparatuses is connectable, the communicator configured to receive an image signal of the video wall from the second display apparatus through the input port and to transmit the image signal to the first display apparatus through the output port so that the image signal is sequentially transmitted for the plurality of display apparatuses of the video wall;
a storage configured to store setting information of the display apparatus to display an image of the video wall;
a signal processor configured to process an image signal;
a display configured to display the image of the video wall based on the processed image signal; and
a processor configured to;
control the communicator to receive master setting information from the second display apparatus which is connected to the input port;
identify whether the received master setting information is different from the stored setting information;
control the storage to update the stored setting information with the received master setting information based on identifying that the received master setting information is different from the stored setting information;
control the signal processor to process the received image signal from the second display apparatus base on the updated setting information; and
control the display to display the image of the video wall based on the updated setting information, and control the communicator to transmit the updated setting information to the first display apparatus which is connected to the output port.

Abstract
A display apparatus, which has an input port and an output port for connection with at least one among a plurality of display apparatuses that constitute a video wall, and easily updates setting information by exchanging the setting information with a display apparatus connected by the input port and regarded as a master display apparatus and a display apparatus connected by the output port and regarded as a slave display apparatus, and a control method thereof. Thus, the setting information for the plurality of display apparatus connected together can be synchronized much easily.

15. A method of controlling a display apparatus which is used for a video wall formed by a plurality of display apparatuses that are sequentially connected to one another, the display apparatus comprising an output port to which a first display apparatus of the plurality of display apparatuses is connectable and an input port to which a second display apparatus of the plurality of display apparatuses is connectable, the method comprising:
-
storing setting information of the display apparatus to display an image of the video wall; processing an image signal received from the second display apparatus based on the stored setting information; displaying the image of the video wall based on the processed image signal; receiving master setting information from the second apparatus when the second display apparatus is connected to the input port; identifying whether the received first master setting information is different from the stored setting information; updating the stored setting information with the received master setting information based on the identifying that the received master setting information is different from the stored setting information; displaying the image of the video wall based on the updated setting information; and transmitting the updated setting information to the first display apparatus when the processor detects that the first display apparatus is connected to the output port. - View Dependent Claims (16, 17, 18, 19, 20)
