    Dual display not working blank screen on 'detect'


    Hi Guys,

    My dual screen has suddenly stopped working on my laptop. Now when I hit 'detect' my laptop screen goes black and I have to force restart the machine and disconnect the second laptop. Is this likely to be a hardware fault? Or how would I diagnose the problem?

    Cheers
