This firmware update only applies to the HyperDrive Slim 8-in-1. We have an article for the Pro 8-in-2 here: https://hypershop.zendesk.com/hc/en-us/articles/360038378871-Screen-flickering-with-Pro-Please-check-this-out-. If you have any other model, this firmware update does not apply to you. Pictured below is the Slim 8-in-1:
If you have the latest version of macOS and you've noticed your screen flickering when an external display is plugged in, you may need to update the firmware. This issue was discovered shortly after the release of the 16" MacBook Pro and also affects the 15" MacBook Pro. To complete the process, you will need Windows 10 through BootCamp, or a Windows computer with a USB-C port that can support video. Windows 10 is free to download (see below) and can be used without a license. If you already have it, you can skip the download labeled '(2)'. Once completed, you will notice the screen no longer flickers.
If you are unable to complete the update or choose not to, we encourage you to reach out to us directly at firstname.lastname@example.org if you have not done so already. We would be more than happy to complete the update for you to allow you to have a properly working HyperDrive.
