A method and an apparatus for outputting an on-screen display (OSD) of a display device are capable of preventing the display device from being damaged by the OSD, which represents an operation state of the display device. If an OSD activation signal which represents an abnormal state of the display device is inputted, a control section controls an OSD circuit section and outputs the OSD. If an output time of the OSD exceeds a predetermined reference time, a control section changes an output position of the OSD. The control section outputs the OSD to the changed output position. The control section repeatedly executes an operation for changing the output position of the OSD based on whether or not the output time of the OSD outputted to the changed output position exceeds the predetermined reference time. Accordingly, the method and apparatus are able to prevent a display device, such as a cathode-ray tube and a liquid crystal display, from being damaged by display of the OSD at one output position of the display device for a long time. Also, the method and apparatus are able to prevent the life of the display device from decreasing.
