Abstract: A screen position sensing method in a multi display system, a content configuring method, a watermark image generating method for sensing a screen position, a server, and a display terminal are provided. A screen position sensing method in a multi display system performed by a sensing server may include receiving identification information of display terminals from a display server, receiving an image output by each of the display terminals from a camera, and determining a screen position of each of the display terminals based on a watermark included in the image of the display terminals and the received identification information.
