    2nd Monitor not detected

    I have same problem. Last night windows 10 did what was listed as the winter update. Since then my second monitor just mirrors the first monitor. Everything worked until the update. I have tried several things, booting with just the one monitor (ASUS)
    and delecting the first (ACER) and then adding both monitors, the control panel just sees the acer monitor. When I ask to detect second monitor it says second monitor not detected. I tried several different resolutions, that didn't help either. The same
    screen appears now on both monitors, but control panel senses only the acer monitor.

    Windows 10 will not detect second monitor and just mirrors the display

    Hi

    My son has a gaming pc with a new NVidia video card and running Windows 10 I believe and we have just purchased an ultra wide gaming monitor for his birthday.

    He wishes to keep his AOC existing monitor and have 2 monitors up and running and to extend the display and not mirror.

    We have connected both via HDMI using I think the term is a HDMI splitter purchased from Amazon.

    We have updated the Nvidia drivers as suggested and ensured all the cables are connected but when we go to Settings and additional display it does not detect the second monitor and the display is mirrored with no option to extend.

    Searched on the web for half a day with no real suggestions. I use 2 monitors at work without issue so cannot explain to him why it will not detect the 2nd display.

    Any help would be greatly appreciated. Thanks.

    Second monitor streamed using Elgato HD60 Pro not detected

    Hi,

    Thank you for writing to Microsoft Community forum.

    • How is the setup done? Do you mean to say that the monitor streamed is not being detected?

    Standard graphic cards that do not have the special DMS port will not be able to send out two separate display signals to two different
    monitors. Seems like the monitor is attached to the onboard GPU port instead of NVidia, if the display is not being detected despite of the GPU supporting dual monitors. You may plug the
    monitor into the NVidia GPU port and check if it’s being detected.

    If the issue persists, it could be due to faulty drivers. I suggest you to install the latest drivers from
    NVidia.

    Regards,
