    Won't detect second monitor after Windows 10 upgrade


    I was automatically upgraded from Windows 7 Home Premium to Windows 10 yesterday and now my second monitor can't be detected. Windows says it doesn't detect the second one, even though it displays two. When I move the mouse, it moves across both screens, but the second monitor essentially just mirrors the main monitor. This only started happening after the upgrade.

    :)

    Windows 10 not detecting my second monitor

    As the topic says, windows 10 isn't detecting a second monitor plugged into my laptop, it detected it on windows 8.1 but after I upgraded to windows 10 it stoped working. And yes, I followed microsofts guide to add a second monitor. Is there anyone that
    could help me with this problem?
