A display apparatus includes at least one display panel including a pixel array configured by a plurality of pixels. The display apparatus further includes at least one controller which receives image data from a host system and controls the driving of the display panel to display the image data. The controller transmits a frame synchronization signal notifying a transmission start time for every image frame included in the image data to the host system, detects a reception start time for an image frame received from the host system, and delays a transmission start time of a data signal corresponding to the image frame to the display panel based on a difference between a start time of the frame synchronization signal and the reception start time.
