    When I connect my two monitors, they both go black.


    I just bought a Sceptre monitor and while trying to set it up with my laptop, I made the Sceptre the main screen. Once I made it the main screen, both monitors went black. What do I need to do to fix this?

    :)

    i have a problem to connect 2 monitors.

    Hi Ron,

    Thank you for posting your query in Microsoft Community.

    • What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
    • How are you connecting to the 2nd monitor?
    I suggest you to follow the steps from this article below:

    http://windows.microsoft.com/en-IN/windows-8/how-connect-multiple-monitors

    [Applies to Windows 10 as well]

    Regards.

    Hi Frank,

    Thank you for your interest in Windows 10.

    I understand the you have tried to resolve the issue and tried many steps. I really appreciate your efforts in resolving this issue. As you have mentioned that switching the cables make both the monitor
    work so I believe its not the driver issue. I would suggest you to try connecting another cable and check if the issue persists.

    Below is the Microsoft help article on How to connect a second monitor/ Multi monitors.

    Note: The steps for Windows 8/8.1 applies to Windows 10.

    Thank You.

    When I connect my two monitors, they both go black.

    Things to do once connected new G-Sync monitor

    I'm getting my G-Sync monitor today.

    I think I have to take the following steps:

    • Connect 1440p G-sync monitor with DP cable
    • Connect second 1080p 60Hz monitor by HDMI
    • Startup PC
    • Reinstall display driver
    • Restart PC (I always do that after display driver install)
    • Activate G-Sync in NV control panel (I believe also V-Sync is auto on after that?)
    • Set my 1440p monitor from 1080p to 1440p
    • Calibrate my 1440p monitor
    Also ingame, I should turn off V-Sync?
    Are there any problems running a second 60Hz 1080p monitor?

    Is there anything else I should do/know?
