  1. Windows cannot detect second monitor


    Hi all, I recently purchased a dual VGA connector to connect 2 monitors to my desktop but it is not showing up on the detect screen on display. I then tried to update my display adapters in device manager but no luck. My display adapter is Intel(R) HD graphics 4600, and uninstalled it and reinstalled it as well. Can anyone please help? Thanks in advance.

  2. Second monitor not detected

    Hello,

    May we know if you've already tried the suggestion provided by Robert Aldwinckle on forums on this

    thread
    ?

    If Windows can't detect your second monitor, it's usually a driver problem. It could be due to your video driver being outdated, incorrect or faulty. It's also possible that your monitor driver is causing the problem.

    Since the issue occurred after the latest update, it's possible that the video or monitor drivers require an update. Try looking for the updated version of the drivers on the device manufacturer's website and follow their instructions.

    If the issue persists, try to roll back the drivers to the last good configuration. To do that, you may follow these steps:

    • Right-click the Start button and select Device Manager.
    • Right-click your device driver, select Properties, and browse to the
      Driver tab.
    • Press the Roll Back Driver option if available, and Windows 10 will begin the process.

    Let us know how it turns out.

    Windows 10 can't detect my second monitor

    Thank you for confirming. We can do the following:

    When the second monitor is not detected, we need to isolate if it's the monitor, the cable connecting them, or the port. We suggest that you remove your 1st monitor, then use the 2nd monitor as your 1st monitor. After that, connect the 1st monitor as the
    2nd monitor.

    Usually, this it's driver-related. Windows 10 won't be able to detect the 2nd monitor if the monitor driver is out of date or faulty. We recommend, rolling back to the previous installed graphics driver and monitor driver if it updated. Otherwise, update your
    graphics and monitor drivers on the Device Manager. To do so, follow the steps below:

    • Type Device Manager in the Cortana search bar and press Enter.
    • When the Device Manager window appears, click the Display adapters and right-click the item below.
    • Select Properties, then Driver tab, and click Roll Back Driver and follow the on-screen instructions.
    • Expand the Monitors, then right-click the second monitor and select Properties.
    • Click the Driver tab, and click Roll Back Driver and follow the on-screen instructions.

    If the issue persists, update the drivers. You can manually update the driver by visiting the websites of your graphics card and monitor manufacturers to get the fully compatible drivers for Windows 10. You can run the Find
    and fix problems with devices and hardware
    to automatically check for driver updates. Additionally, we'd like to know the make and model of your graphics cards and monitor?

    Post back anytime at your convenience.
