A multi-vision system and a method of controlling a display device usable in a multi-vision environment are disclosed. The multi-vision system includes a video source providing a video signal, a user input unit receiving multi-vision arrangement information from a user, a display device coupled to the video source for receiving the video signal. The display device, which is further coupled to the user input unit for receiving the arrangement information, initially determines an image portion of the video signal on the basis of the received arrangement information, adjusts a size of the determined image portion, and displays the size-adjusted image portion. The arrangement information indicates a user-preferred multi-vision arrangement and a position of the display device in the multi-vision arrangement.
