  1. Second monitor flickers when extended or duplicated


    Windows 10 Pro build 19045.2251GPU: RTX 2080 - latest nvidia driversMonitor 1: 1440p 165hz via DPMonitor 2: 1080p 60hz via HDMI these are set correctly in display settingsI have a strange issue where my second monitor will flick on and off when extended or duplicated.Sometimes it's completely fine, other times it will flick on and off constantly, 1 second at a time. It may do this for an hour and then suddenly be stable with no issues. It may flick off once and then go back to being stable. I've not found a consistent pattern. Restarting my PC or flicking through the Win+P options seem to ha

  2. Problems while extending and duplicating on my second monitor

    Hi there!

    So I wanted to get a dual monitor for my laptop so I found a monitor at home. Its an NEC LCD monitor which takes a VGA cable for input. So I got a HDMI to VGA adapter, plugged it into my Laptop (Asus X510UAR) and it worked flawlessly. All the projection modes such as PC only, Duplicate, Extend and Second Screen.

    But when i wend to adjust the resolution for the second monitor in the display setting, idk what i pressed accidentally, but now my second monitor shows a black screen during Duplicate mode and while extending to the dual monitors, the mouse cursor does shift to another screen, but the dual screen is still black(even though apps are working on it. And when i switch to only the second screen, the second screen works completely fine(Indicating that the hardware is absolutely fine)

    I've tried with many forum suggestions such as changing the resolution of both the screens as well as changing the primary monitors and the configuration of both the screens and orientation as well but no luck. I've even tried changing the Microsoft administrator account to a new account to reset to the default setting but no luck there as well. And other ways to reset to the default setting weren't possible on my laptop.

    Please do suggest what could be the possible ways to solve the issue which wasn't there when i initially started.

    Thanks!

    Windows Version 1903(OS Build 18362.592)

  3. Second monitor not detected after update

    Hi Tom,

    There are several reasons that could have caused the issue you are experiencing. One of these is the update you previously performed in Windows, either it was not configured properly by the system or the update components were corrupted. Kindly answer the
    following questions for clarification:

    • Have you tried updating the monitor and display drivers?
    • Have you tried to use another user profile to check if the issue re-occurs?

    Furthermore, we suggest that you add the other monitor manually. This is to ensure that the second monitor is still connected after the update. Here are the steps:

    • Type connected devices and open Connected Devices on the
      Windows Search bar.
    • Click Add devices.
    • Select the Second screen.
    • Pick one of the 3 options: Duplicate, Extend, and the Second screen only.
    • The Duplicate option will duplicate the primary display to secondary display.
    • The Extend option will unite two monitors so you can use them both as one.
    • The Second screen only option will, obviously, disable primary and use only the secondary monitor.
    • Once you’ve chosen the preferred mode, save changes.

    We're looking forward to your response.

  4. Second monitor flickers when extended or duplicated

    Windows 10 doesn't show native display for second monitor

    Hi,

    In order to for your Windows 10 to show the native display for the second monitor, you may revert all screen settings back to default, and see if this resolves the issue. If it doesn't, you may try these steps:

    • Press Windows key + P.
    • If your monitor settings is on Duplicate, try choosing
      Extend
      .
    • If your monitor settings is on Extend try choosing the
      Duplicate
      .
    • Check the resolution if both monitors are showing the same resolution value.

    Let us know the result for us to assist you further.

    Regards.
