I have major issues most of the time getting this to connect two screens at once. So much so that I have given up and just run one of the monitors to the laptop. Single monitor seems to work fine and all the other connections work well.
I am having a lot of trouble with the docking station. Something is not working right with the communication with the docking station and the computer. All of the external items are dropping out. At this point the docking station is only good for power.
The newer block dock requires less space than the original docks. I have had no problems with connections, with device communication, or device recognition. My complaint or suggestion is to remove the DP ports and add more USB-A and USB-C ports. I had to add a USB hub for the rest of my connections.
