Data for controlling the size of an image is stored in a memory when a multi-synchronization mode display is fabricated, and the image is automatically controlled using the stored data. A technique for controlling an image on the multi-synchronization display, includes: confirming if there is an input from a user for controlling the image; setting a variable range of a reference value determined when the display was fabricated, when it is confirmed that there is no input from the user; when the variable range is set, confirming if the user has operated an up-control/down-control key for controlling the image; and when it is confirmed that the user has operated the up-control/down-control key, increasing/decreasing data according to the up-control/down-control operation of the user.
