Please Please try the following troubleshooting steps:

• Lower the resolution or refresh rate, then check whether the issue persists.

• Test the hub with another laptop or display to see if the issue persists.

• Try a different or shorter video cable to determine whether the original cable is causing the issue.

• Disconnect the hub from your laptop and unplug all devices from the hub. Wait at least 5 minutes, restart your laptop, and reconnect all devices. Then check whether the issue is resolved.

If all of the steps above cannot help you locate and resolve the problem, please contact Anker Customer Support for further assistance. Briefly mention the steps that you’ve already tried for a faster solution.
