My advice is to not use docks. They cause too much troubles. It's game over as soon as you try to plug multiple displays and/or 4k displays. Connect each display with a dedicated cable, thunderbolt to HDMI. Works better. The only issue then is with Macbooks only having 1 or 2 ports, not much you can plug. Use a bluetooth mouse/keyboard to save ports.
