How to find MAC address on Microsoft 4K Wireless Display Adapter

We have a bunch of Microsoft 4K Wireless Display Adapters UTH-00036 deployed in our conference rooms, and I need to get the MAC address of one of them to whitelist it on the network. The problem is, I can't find that information anywhere, neither on the device itself nor through Windows when connected. I've searched through the settings and manuals for quite a while now without success, and this is slowing down our deployment for our conference rooms. Does anyone know the correct way to get the MAC address for this device?

    Hi Cheng Ying,

    The Microsoft 4K Wireless Display Adapter (model UTH-00036) does not expose its MAC address through the Windows connection UI or the Microsoft Wireless Display Adapter app. The MAC address is only visible at the network layer once the adapter is powered and broadcasting. The most reliable way to obtain it is to connect the adapter to a display, let it boot fully, and then scan your network for active devices. You can do this from your DHCP server lease table or by running arp -a from a client machine immediately after connecting to the adapter’s SSID. The MAC will appear as the hardware address associated with the adapter’s IP.

    There is no printed MAC label on the device itself, and Microsoft’s documentation confirms that the only way to retrieve it is via DHCP or ARP inspection. If you are whitelisting, the best practice is to temporarily allow the adapter to connect, capture its MAC from the DHCP lease logs, and then add it to your whitelist. If your environment uses managed switches, you can also check the port’s CAM table to see the MAC address once the adapter is plugged in and active.

    The provided information does not describe any supported way to read or derive the MAC address of a Microsoft 4K Wireless Display Adapter (UTH-00036), either from Windows, from the adapter UI, or from documentation. No method for discovering or managing the adapter’s MAC address is documented in the available context.
