    Windows 10 Display Settings fails to detect 2 out of 3 monitors

    Triple monitor setup has worked well for years on Win7, but Windows 10 Display Settings fails to detect 2 out of 3 monitors.

    Device Manager says both Display adapters are "working properly". The latest drivers are installed for both. I also tried downloading the Intel driver direct from Intel and installing it, but that does not fix the problem.

    Device Manager says all three Monitors are "working properly".

    Adapters are Intel HD Graphics 4000 and NVIDIA GeForce 8400GS.

    Monitors are Dell U2412M (Digital), and two Samsungs reported as Generic PnP Monitor.

    The only monitor that is working is a Samsung plugged into the analog 9-pin port on the GeForce adapter.

    The Customize your display setting "detect" option reports "Didn't detect another display". Oddly, the display it does detect is numbered "2".

    Windows 10 is fully updated.

    Any ideas?

    3 monitors won't display in settings windows 10

    Thanks for trying but this was not the problem. I have it solved. I had a hdmi splitter for the 2 external monitors, which was suggested by Staples. An hdmi splitter is stupid because whatever is on 1 monitor is on the 2nd monitor, DUH, it's a splitter.
    And this is why in "Display Settings" only my laptop monitor & 1 monitor was shown. Solved by returning the hdmi splitter, plugging in 1 monitor directly to my laptop hdmi socket and getting a usb to hdmi adapter which plugs into my laptop usb socket & my
    2nd monitor plugs into the hdmi side of the adapter. Instantly all 3 monitors were shown in "Display Settings".

    Second monitor signal lost but recognised in Display Settings?

    1] Update Driver software
    2] Manually detect Monitor settings
    3] Hardware troubleshooting

    Above can be a checklist and if 1 and 2 don't issue will be detected on the third step i.e hardware issue.
