Abstract: The present invention relates to a method applied on displays for recognizing video signal timing of analog input. The present invention employs the horizontal-synchronized-signal interrupt value to distinguish among its inputted video signal timing, allowing to recognize its pixel and correctly display its corresponding video signal timing even when the inputted signal timings share the same horizontal frequency, vertical frequency, and polarity. In case when the display is displaying incorrect video signal timing, the present invention also allows inputting a switch signal to adjust its display mode accordingly, enabling the display to show the correct resolution of the video signal timing under normal operation.
