I was using an inexpensive dock to connect my Mac Book Pro with four USB-C ports to my HDMI monitor. One day the dock failed completely. Too late to return it and it isn't even for sale anymore. So I ordered this AmazonBasics dongle, received it two days later, and I am back to using my large monitor. As with all AmazonBasics products, it seems, it is well made, properly engineered, and just works. I love buying things from Amazon with Amazon's name on it. Plug and play perfection. I have talked to engineers who have shown me that HDMI is not always the same. I can't tell you if this will work in every situation, but it worked perfectly for me.
