Please try these troubleshooting steps:
-
Confirm if the USB-C port on your laptop supports DP Alt Mode (display output). Check your laptop's user manual, contact the seller, or visit the manufacturer's website to verify.
-
Update the graphics driver of your laptop to see if it resolves the issue.
-
Test the device with another laptop that has a USB-C port supporting DP Alt Mode.
-
Try using a different HDMI cable or monitor and lower the resolution or refresh rate to see if it resolves the issue.
-
Unplug the hub from your laptop and disconnect all devices for at least 5 minutes. Reboot your laptop and reconnect the hub to see if this resolves the issue.
