    Hello CK,

    There are a few reasons why you may be experiencing flicker in your video. Please refer to the recommended computer specifications from this link:

    Video flicker may also be linked to your USB 3.1 controller. Make sure you have the latest driver available through Windows update.

    Also, check your anti-flicker setting in Logitech Capture and select the anti-flicker rate based on the electrical frequency in your location.

    Could anyone help? The image flickering is quite serious, and this is a brand new webcam that I've just bought.

    Hi Alan, thanks for reaching out and sorry to hear about the experience with C920. Please take a moment to follow the troubleshooting steps below to try to solve the issue:

    1. Make sure webcam is set as default not just in the Logitech
    Capture but also on the application that uses the webcam such as Skype, Facetime, and etc.
    2. Re-seat to another USB port. Bypass the use of KVM switch boxes, port replicators, docking stations, and USB hubs if any
    Prefer using USB 2.0 rather than USB 3.0 ports.
    3. Try another application so that we can check if it is only happening on a certain app or not.
    If that did not work,
    4. Uninstall the Logitech Webcam software and install the
    Logitech Capture
    5. Try a different computer so that we can check if it is only happening on a different computer or not.

    If you think you’re still having trouble after following this troubleshooter, don’t hesitate to contact us and we’re happy to continue helping you.

    Changing to PAL 50Hz helps BUT

    On Mac OS every time the computer gets restarted the Logitech WebCam control program changes the anti flicker setting back to NTSC 60Hz.   So any time you restart the computer need to go back and change to PAL 50Hz again.

    This is very annoying as it should keep and register the change.

    Using the latest Camera Settings version 3.0.23

    Hi Andrew,

    We suggest you to please uninstall LCS / Camera settings application and install Logitech Capture application from the link below, as Anti flicker settings is available on Capture.

    Note; Once the link is opened, click on All download and select the operating system you're looking for.

    Click on the link below for Logitech Capture guide and check the details on page 11 has anti flicker settings

    Feel free to contact us if you have any additional clarifications, and we will be happy to help.
