    Hi,
    

    This is confirmed on a prototype board using the ADV7480. 
    

    HDCP authentication fails when HDMI is connected from a notebook PC to a prototype board, but authentication succeeds with a DVD player. We are trying with the script file recommended by ADI. 
    

    Please tell me what is causing this.
    

    

    Best regards.
