A method and apparatus to display user-guide on-screen display information about a status of an external device on a display device connected with the external device may include attempting to detect a signal from the external device when the display device is in an external input mode, displaying OSD information indicating that a signal is being detected from the external device, for a predetermined time, if no signal is detected in the signal detection operation, and preventing the OSD information displaying operation if a signal is detected in the signal detection operation.
