      Hello,
      I have this parameters, who works great on my CRT TV, but I have some strange noises.
      I think horizontal sync pulse, vertical sync pulse and pixel clock frequency are not configured well....
      Here is my parameters :
      Horizontal resolution : 320
      Horizontal front porch : 32
      Horizontal sync pulse : 20 (by default)
      Horizontal back porch : 61
      Vertical resolution : 240
      Vertical front porch : 28
      Vertical sync pulse : 7 (by default)
      Vertical back porch : 28
      Frequency : 60
      Pixel clock frequency : 6400000 (by default)
      With this parameters, I have this :
      Horizontal scan rate : 14.78 kHz
      Vertical refresh rate : 48.78 Hz
