The present invention relates to a display device and a method for identifying a display mode for a display device which receives a synchronous signal and a video signal. The display device measures a frequency or cycle of the synchronous signal, compares the measured frequency or cycle of the synchronous signal with a reference frequency or cycle to identify the display mode, and changes the reference frequency or cycle including a first and second reference value selectively for the step of comparing. According to the present invention, the display mode is stably identified.
