Provided is a display apparatus including: a display panel, a backlight unit configured to output light, a backlight driver configured to drive the backlight unit by identifying a dimming section of the backlight unit corresponding to a variable refresh rate of an image, based on reception of a sync signal, a memory storing at least one instruction, and at least one processor configured to execute the at least one instruction. The display apparatus is configured to identify a first output frequency of a sync signal that varies based on the variable refresh rate of the image, output the sync signal to the backlight driver in a second output frequency that is a higher frequency than the first output frequency, based on predetermined information, and drive the backlight unit corresponding to the variable refresh rate of the image, based on receiving the sync signal in the second output frequency.

Display apparatus and driving method thereof

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.
