    Hi,
    

    I'm struggling with the ADV7850 in AutoGraphics mode when dealing with VGA non-VESA resolutions. I want to use sample data so that ADV7850 can support more resolutions.
    

    ps: I don’t have an evaluation board.
    

    

    Does anyone have code that calculates the pixel clock (pll_div_ratio), free run mode line length (ch1_fr_ll) and free run lines per field (cp_lcount_max)?
