DisplayPort and Acer Dock Problems

I have an Acer v15 Nitro laptop running Win 10 and am connecting it to an Acer docking station via a USB 3.1 cable. From the DisplayPort connector dock I'm attempting to connect an external display using the DisplayPort connector on the monitor.

 

At first when I connected everything up, I was able to see the desktop on both the laptop's own display and the external display. All looked good. However, after disconnecting the laptop from the dock and then later reconnecting I'm got an error message from Windows: "DisplayPort connection might not work. Try using a different cable." What cable is it referring to? The video cable or the USB cable? I tried another USB 3.1 cable and it worked again for exactly one time but after disconnecting and reconnecting I got the same error message.

 

Before even starting this I upgraded the BIOS on the laptop and updated all the Windows drivers using the Acer update utility. I even did the reset thing on the laptop where you insert a pin into a hole on the bottom of the laptop.

 

Finally I went to went to Acer's support site and found a newer BIOS than the update utility provided. I installed it and again, I had the one time only success with the external monitor.

 

Any insight? Thx.
