- [Microsoft Wireless HDMI adapter](https://www.microsoft.com/accessories/en-us/products/adapters/wireless-display-adapter-2/p3q-00001) - The **only** reason I'm recommending this Microsoft product is because there is no possible way for it to extract any data and ship it off to Microsoft. I use it and it works great.
