Please Please try the following troubleshooting steps:

• Confirm that your laptop's USB-C port supports DP Alt Mode (video output). Check the user manual, contact the seller, or visit the laptop manufacturer's website.

• Update your laptop's graphics driver.

• Test the hub with another laptop that has a USB-C port supporting DP Alt Mode to see if the issue persists.

• Try a different HDMI or DisplayPort cable or another display.

• Disconnect the hub and all connected devices for at least 5 minutes. Then restart your laptop and reconnect the hub.

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.
