Abstract: The present disclosure relates to a video wall. The video wall according to an embodiment of the present disclosure comprises: a plurality of displays disposed adjacent to each other; an image divider configured to divide an input image into a plurality of images; and at least one controller configured to control a plurality of image display apparatuses, wherein in response to a video displayed on the plurality of image display apparatuses being repeatedly played back, the controller is configured to store a boundary area and transmit the stored boundary area to adjacent image display apparatuses, and the respective image display apparatuses synthesize a received boundary area with an image area to be displayed, and display a portion of the synthesized image. Accordingly, an occurrence of black areas may be reduced while reducing afterimage on the video wall comprising the plurality of displays.
