ABSTRACT:
A method is provided for accurately sampling pixels in a fixed-format display, which is connected to a host computer through an analog video display adapter. The method comprises the step of confirming that the fixed-format display is able to receive a pixel clock signal from the analog video display adapter. Another step is sending the pixel clock signal across an analog video sync line so that synchronization data and the pixel clock signal will be contained on the analog video sync line. An additional step is receiving the pixel clock signal in the fixed-format display. A further step is applying the pixel clock signal in the fixed-format display to sample pixels.
