    monitor not detected


    In Windows 7, I was using extended display:
    primary=notebook screen
    secondary=external monitor


    Ater installing Windows 10, the primary screen is not detected by the system; only the external monitor works.

    In "System > Display" it says "didn't detect another display".

    The primary screen works only a few seconds while starting the pc, than it goes black and dead right before Windows logon screen.

    Already updated/installed/resinstalled/disabled/enabled drivers, but nothing worked.

    What video card do you have? Have you gone to Windows Update yet?

    SOLVED!
    BIOS was the problem. Mine was version A09, after upgrading to A12 (Dell official) the system detected the notebook screen.
