If your USB4 Multiport Adapter with 8K HDMI isn’t detected, try these steps:

• Make sure the USB-C connector is fully seated in your computer’s port.
• On a Mac, if you see a prompt asking to allow the accessory to connect, click Allow.
• Try a different USB-C/Thunderbolt port on your computer.
• Check System Information > USB (Mac) or Device Manager (Windows) to see if it appears.
• Test on a different computer to see whether the issue is the adapter or your computer.

If the problem continues after these steps, submit a support request.
