Review on USB C To Dual HDMI Adapter, 4K Thunderbolt 3 To 2 HDMI 1 In 2 Out Switch Splitter, USB 3.0 Hub And Type C To HDMI Converter For MacBook/MacBook Pro 2020/2019/2018, MacBook Air 2020/IPad Pro 2020 by Marcus Price

Works great for my setup.Sequence of events:1. Set it up, with a USB-C extension from this to my computer2. It's not working.3. Keep trying, still not working.4. Try some more, with a different laptop. Still nothing.At this point, I finally figured out that my USB-C extension cable was for power only, not video. Once I got the right cable in place, it worked great.So: if it's not working for you, double-check its connection to your computer and make sure you're using the right cables.The End.
