    Also, if you click on "Fixing Screen Flickering" it goes here which also doesn't solve the issue...

    Troubleshoot screen flickering in Windows 10 microsoft.com

    you should do the things recommended in the article above like make sure you have latest Windows Updates, but it didn't fix my problem.


    I was using a standard HDMI cable with this HDMI-to-USB-C adapter and was having this issue regularly:

    Solution:

    I then read this reddit post which led to this list of active adapters and cables. Key point made in the article is DisplayPort is simpler than HDMI. I had a DP cable on hand so I just needed a DP-to-USB-C adapter to connect External Monitor to dock. I ended up buying this adapter from the list and it solved my problem:

    Monitor goes black

    My external monitor loses connection with my laptop 3-4 times per week. First it goes to blue screen with no connection message, then it goes black. Sometimes the image returns in 1-3 minutes, often never without ctl-alt-del then signing in to my account.
    Is this a computer video problem or possible virus?

    Surface Laptop 3 with external monitor

    Hi All,

    Has anyone come across an issue with an external monitor blacking out while connected to a Surface Laptop 3? I have the laptop connected to a widescreen laptop with the Surface Dock. Both work fine however, once every hour or so the external monitor blacks out and comes back.

    I've completed the following:

    • Updated laptop drivers and firmware
      • Updated monitor drivers
      • Swapped out monitor
    [/LIST]

    External monitor goes black for 2-3 seconds, every few minutes

    Laptop goes to black screen in 2 minutes.


    Hello,
    Just installed Windows 10 yesterday. I have a Toshiba laptop.
    When no programs are running and I'm not working on the laptop, it automatically goes to a black screen now after 2-3 minutes. When I then touch a button or the mouse, it goes back to normal screen, and I can also see the internet connecting again.
    All my screensavers/shutdowns are set on 10 minutes or more.

    What can cause this?
