  1. Windows 10 1 out of 3 Monitors is Not Working


    Hi Community,I have some issue regarding the 3 Monitors setup. It was worked well previously when using 2 monitors but now it suddenly doesn't work anymore for both 3 monitors and 2 monitors.I have MSI Prestige 14 A11SCX connected to Dell WD19TB Docking Station.

    Windows 10 with 3 Monitors

    No, Windows 10 is not allowing me to extend my desktop to a 3rd display.

    I understand how to set up 3 monitors, and it was working fine in Windows 7. Windows 10 shows all 3 monitors, but only allows me to use 2 at a time. From my reading through these forums and other searches, it looks like many people are having this same issue.

    I am using 2 DVI monitors and 1 HDMI; not a DisplayPort. It looks like people can get 3 or monitors working with a DisplayPort, but I haven't seen any solutions to getting 3 standard monitors functioning in Windows 10. Are there any other suggestions or
    fixes from Microsoft for this?

  3. Windows 10 Update - Now my dual monitors do not work

    Hi,





    One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:



    • Which Windows 10 build are you using?
    • Have you already tried performing the troubleshooting steps suggested by
      Mauro Cavallin on June 16, 2017?
    • Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
    • What troubleshooting steps have you done so far?


    We will be waiting for your response.

    Does Windows 10 Support 3 monitors?

    Hi Chuck,



    As per the description, you are experiencing issue with you want to know Does Windows 10 support 3 monitors because you are able to see the display on 2 monitors but the third one is grayed out.



    I certainly understand your concern.

    There could be a possibility that this issue might have occurred due to outdated display drivers or corrupted drivers on the system.

    I would suggest you to try the following methods and check if that helps.



    Method 1:

    Run inbuilt Hardware & Device troubleshooter


    First, let’s try running inbuilt Hardware and Devices troubleshooter to get the problem automatically detected and fixed. It checks for common issues and makes sure that any new device or hardware attached to your computer
    was installed correctly.

    • Now click on view all option.

    • Click on Hardware and Device and follow the prompts to run the troubleshooter.
    If the issue persists, follow method 2

    Step 1: Update the Display driver.
    Please follow the steps given below to update the display driver.

      Run.

    • Click or tap Settings on the right side of the screen, and then select Install optional updates from the left results.

    • When the Windows Update control panel opens, click on “Check for Updates” on the top left corner to receive a fresh list of updates.
    Step 3: If the issue persists, I would suggest you to uninstall and reinstall the Display driver. Please follow the steps mentioned below to uninstall the display driver.


    • Open Device Manager.

    • Expand Display adapters.

    • Right-click the display card driver and click
      Uninstall.

    • After the un-installation is complete, reboot your computer as soon as possible.
