Review on 🖥️ MacBook Pro Dual Monitor Docking Station - 14 in 2 Triple Display USB C Dock with 2 HDMI, 18W PD Charging, 4 USB A, 100W AC Power Adapter - for MacBook Pro/Air Thunderbolt 3/4, Mac OS, Type C Laptop by Mike Shah

Only outputs 4k@60Hz from one of the ports (and crashes from time to time). The other port never outputs 4K@60Hz off *If you use this port alone it will not sync properly if you set it to 4k@60Hz (fails) *If you use it alongside a working one you will only get 4K@30Hz as Option.I still haven't found a docking device (not even a two wire device like this one) that can play 4k@60hz on 2 screens at the same time.I have to buy 2 keys to make this work.
