An apparatus and method are provided for automatically adjusting a pixel sampling clock frequency and phase of a video display to match the frequency and phase of a pixel clock used to generate an incoming video signal being received by the video display. Voltage transitions are detected between pixel intensities in a video signal. The voltage transitions are compared with pixel sampling clock pulse signals of the video display in order to correctly match the frequency and phase of the video signal, and thus produce a more stable and noise-free image on the video display.
