Abstract: Disclosed is each display apparatus interconnected in series based on a DisplayPort standard. Each of the display apparatus includes a processor configured to request a front-stage display apparatus to confirm whether a first image signal is normally transmitted during an operation for displaying an image based on the first image signal of a first source device received from the front-stage display apparatus, control to display the image based on the first image signal received from the front-stage display apparatus in response to receiving a confirmation signal confirming whether the first image signal is normally transmitted from the front-stage display apparatus, and control to receive a second image signal of a second source device from a rear-stage display apparatus in response to not receiving the confirmation signal from the front-stage display apparatus.
