I see this allows for 2 HDMI monitors, can these monitors be independent or are they mirrored only?

Yes, the monitor can be independent (extended) if you Mac supports it. Using a MacBook Pro 16 (2019) and the CalDigit Thunderbolt 3 Mini Dock (Dual HDMI version) I was able to display at the same time: - Safari on a 27" Samsung screen, full HD, using HDMI cable - Play a TV show on my Samsung SmartTV, full HD, using HDMI cable (I don't have the Apple TV device. I was using the Apple TV app running on the Mac). The subtitles worked, and the sound was displayed on the TV. - Pages on the MacBook Pro screen How to do it: - Plug the dock into the Thunderbolt 3 port of the Mac - Plug the HDMI from the screen into the dock: It is going to do mirroring automatically after a few seconds - Go to Apple menu / System Preferences / Displays - Go to Arrangement tab - Uncheck "Mirror Displays" - Move the blue rectangles representing the screens so it matches your actual setup - Move the white menu bar to the other screen if needed - Plug an additional screen if you wish and move it to match your actual setup if needed - For the sound to be played by the TV instead of the MacBook Pro speakers: Click on the top-right speaker icon and select the TV as output device
