description In a display device and its synchronizing signal detecting device and a detecting method, an image separation signal and a SOG separation signal are separated from an inputted image signal, and then whether a period variation of the separated signal is under a reference period variation and whether a ground section of the separated signal is under a reference time are determined. As a result, whether the separated signal is the image separation signal or the SOG separation signal is exactly detected. As a result, normal operation of the display device is achieved irrespective of DPM mode.
