    Cant mirror desktop between laptop and projector

    When I connect my laptop to a projector, the projector becomes my primary
    monitor and my laptop screen goes black. The function key combo won't work to
    switch displays. I can't switch the displays in the change display panel
    (i.e. set up my laptop as the primary monitor - the option is greyed out).
    When I turn the presentation feature on in the control panel it doesn't
    detect another monitor that I can switch the settings for. I need to do my
    presentations with my desktop on both my laptop and the projector. Does
    anyone know a work around? Thanks

    Contact your laptop vendor.
    On any laptop I have ever used the Fn function key option has always
    permitted Laptop only, Other display only, or both.

    set the laptop screen and the external screen resolutions to the same
    value and see
    if that makes any difference.
