    External monitors extending issue.

    I am trying to connect 6 external monitors to my laptop running on windows 10. I am using DVI-D dual-link to HDMI cable to connect the monitors to the HDMI splitter and HDMI to HDMI cable to connect the splitter to the laptop. There
    is just one problem when I am extending the screens, the external monitors seem to duplicate themselves rather than extend. So instead of 1 to 7 for all monitors combined, all my laptop only detects 1 and 2. 1 being my laptop and 2 being all the other external
    6 monitors. That means that all the external monitors showing me the same thing as in they duplicate and not extend. Any suggestion on it can be fixed so all the external monitors become the extension of my main laptop and do not duplicate?

    2 External monitors - 1 to extend and 1 to duplicate

    Hello,

    Does anyone know of a way to connect two external monitors to a Surface Pro 4 and have one monitor be duplicating the surface screen and the other monitor extending that screen?

    Thanks for the help!

    External Screen works only with extend, but not with duplicate.

    Extended screen with wndows 10

    I have a new HP laptop and an LG external monitor and want to extend the screen.
    As a starting point, I tried to extend the screen just using the laptop and the monitor.
    I pressed the windows icon and "P".
    Four options appear. "PC screen only", "duplicate" and "second screen only" all work.
    However, "extend" option appears not to work.
    The monitor has the expected image (if a website is opened) and an operational mouse pointer. However, the laptop screen shows none of the webpage and shows only the wallpaper image present when the device is turned on. The mouse pointer can be moved between screens.
    The web page is certainly not extended across two screens.
    Any suggestions?
    Thanks Michael.
