  1. External monitor going black


    I have a laptop with a damaged screen, so I started using a flat screen TV as a monitor connected with an HDMI cable. I actually have 2 different Dynex flat screens. Both used to work fine. Now one the larger, newer one will display for a short period then go black. The smaller, older one works fine. I've reset to default all of the setting on the TV, and tried every combination of Display Setting on the laptop, but nothing seems to help. If I put the laptop in Sleep, then wake it up, the monitor comes back, but will go black again eventually. It's driving me crazy. Windows 10 is updated.


    After I reset all of the TV settings to default, I thought it had been fixed. I was in the laptop Display settings, and I left it there for an hour and it didn't go black. But when I started using the computer, I changed the volume using the icon in the system tray, and it blacked out. I did the Slepp/Wake Up, and tried to change the volume again, and it blacked again.


    It's driving me crazy. Any help would be appreciated.

    :)

    External monitor blanking often

    Hi,

    Please answer these questions to assist you better.

    • What is the make and model of your computer and external monitor?
    • Have you installed all pending Windows and driver updates?
    • Do you get any error message?

    I suggest you to install all pending Windows updates in your PC and also update Display drivers. Follow the steps below.

    Step 1: I would suggest you to check and install any latest Windows Updates available.

    • Go to Start and then Settings.
    • Click on Update and Recovery.
    • Check for updates under
      Windows Updates.
    • Restart the system and check if the issue is resolved.

    Step 2: Please refer to the following Wiki article created by
    Andre Da Costa on How to: Install and Update drivers in Windows 10.

    How to: Install and Update Hardware Drivers in Windows 10

    Do let us know if you still get random black screen in the external monitor. Thank you.

    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]

  4. External monitor going black

    my acer aspire laptop dosent detect external vga monitor .

    Hi Sivaram,

    Thank you for writing to Microsoft Community Forums.

    1. Since when are you facing this issue?
    This issue might be happening because of the faulty drivers. That’s the reason you are getting intermittent connection on external monitor.

    However, you may try the below suggested steps.

    Step 1: Try connecting on a different monitor and check if the issue still persists.

    Step 2: Try using a different VGA cable to connect with external monitor and check the status of the issue.

    Step 3: Update display driver adapters

    You may refer the article
    Update drivers in Windows 10
    and check the status of the issue.

    Step 4: Check for an updated Video driver on the

    Acer drivers and Manuals page
    .

    For more information you may also refer

    Hope it helps.
