Abstract:
A display apparatus, equipped with a common input terminal inputting different video signals, can discriminate the type of an input video signal entered from the common input terminal. The display apparatus includes an input terminal inputting different video signals. A synchronizing signal separation unit separates a synchronizing signal from a video signal entered from the input terminal. A frequency measurement unit measures a frequency of the synchronizing signal. An input signal discrimination unit discriminates the video signal entered from the input terminal based on a type of the synchronizing signal separated by the synchronizing signal separation unit and a measurement result obtained by the frequency measurement unit.
