An automatic coarseness setting method in a video display apparatus is provided. According to the automatic coarseness setting method, when an automatic adjustment command is input or when a new mode video signal is received to the video display apparatus, a pixel clock of an input video signal is detected, and a coarseness value is automatically set based on the detected pixel clock. Accordingly, it is possible to provide optimum video display using a coarseness value most suitable for the input video signal.
