    Hi，

    The total\Hbp\Hsync\Vbp\Vsync parameter should let the screen company to provide, which should from the screen spec.

     Below is the example that we need to have. (PCLK = Htotal*Vtotal*frame rate)

    Total Horizontal Pixels = 1946
    Total Vertical Lines = 2432
    Active Horizontal Pixels = 1836
    Active Vertical Lines = 2372
    Horizontal Back Porch = 38
    Vertical Back Porch = 36
    Horizontal Sync = 36
    Vertical Sync = 2
    Horizontal Front Porch = 36
    Vertical Front Porch = 22
    Horizontal Sync Polarity = Positive
    Vertical Sync Polarity = Positive
    Bits per pixel = 24
    Pixel Clock = 283MHz
    Regards,
