• Lower the resolution or refresh rate to see if the issue persists.

• Test with a different laptop or monitor to see if the issue persists.

• Try using a different or shorter HDMI cable to determine if the original cable is faulty.

• Disconnect the hub from your laptop and unplug all devices from the hub for at least 5 minutes. Afterward, restart your laptop and reconnect everything to see if the issue is resolved.
