  1. 3rd monitor not detecting


    Hi, Just after some help, Windows 10 updated to version 1909, and now the 3rd monitor will not detect, i have AMD Radeon HD 7900 Series graphics card, The catalyst control centre and eyfinity is only detecting 2 screens as well, I have tried restarting my PC, Uplugging and plugging back in the cables, updating the drivers, reverting back to old drivers, everything that google tells me to do, and even reset my pc, i can get each screen to work by extending, duplicate or using second monitor but only 2 screens will ever work at 1 time.


    Hope someone can help.


    Cheers

    :)

  2. 3rd monitor doesn't connect

    Hi,

    Thank you for posting your query on Microsoft Community.

    To better understand your query, kindly reply to the following questions.

    1. Did you try setting up the cables again?

    2. Did you try giving the recommended resolution and check if the monitor is detected?

    I would suggest you to make sure that the monitors are connected to the correct video port.

    However, you can go to the device manager and disable the monitor which is not working.

    Follow the steps below.

    • Press Windows key + X key and click on
      Device Manager.
    • Expand the Monitors.
    • Right-click on the monitor and select Disable.
    • After sometime, try re-enabling it and check if the device gets detected.
    Hope this helps. Please respond if you have further related queries.

    Regards,

    Windows 10 not detecting 3rd monitor

    Hi

    I mentioned at start of this thread the following

    In display settings, it is only detecting 2 monitors. One of these is my Laptop and the other is my monitors. Both the monitors are showing the same display but are being counted as 1 monitor

    So your latest suggestion is not working either.

    Windows 10 not detecting 3rd monitor

    Thank you for your response. If the above steps did not work, let's try a different approach. Try switching the third monitor to either of the two monitors that have working connection and see if it will detect the third one. If the monitor can't still be
    detected after switching places and connections, it's either the splitter cannot support multiple connections or broken, or the video card has problem.

    Keep us in the loop with the result.
