  1. Security Updates cause my main monitor to go black for a few seconds


    I've had this issue happen to me a few times now this year and every time I've had the black screen happen, I could check the windows update history and always find security updates that had just then been downloaded. Does this happen to anyone else? I was thinking for a while that it might be a broken displayport cable, which I ruled out by getting another one, and it doesn't happen during "intense moments" such as playing for the pc stressful games, it always happens when I'm just on my desktop, doing close to nothing.

    It's not the biggest deal in the world I suppose, but any ideas on what I can try besides a clean install?

  2. 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.

    Hello Oliver,
