    initial v1  
    66- I connected a 1280x1024 analog screen. I can set modes and refreshrates: all good.
    77- I connected a 1920x1080 analog screen. I can set modes and refreshrates: all good.
    8 - I looked at the syslog, for the 1920 screen, and compared the PLL settings done to the settings done for you in the non-working setup: they are -exactly the same-.
     8- I looked at the syslog, for the 1920 screen, and compared the PLL settings done to the settings done for you for the VGA screen in the non-working setup: they are -exactly the same-.

    1010There's just one conclusion I can think of: the PLLs are connected just the other way around. the PLL programmed for the internal panel actually programms the VGA output and vice versa. This would fit exactly the observations above.
