Need to re-plug every time after restarting

[steven-]

Hi,
I just got a Dell USB 3.0 Ultra HD/4K Triple Display Docking Station (D3100).

Everything works fine. However, for some reason, I have to replug and open my laptop every time once I restart my PC (windows 10). If not, both monitors linked to the dock will show nothing but you can tell that there is a signal. Once I open the laptop, it shows nothing neither. I have to plug out the USB 3 cable and then the laptop will show the windows welcome screen. I have to log in and then replug the cable so that both monitors will work.

Thanks in advance for any help you can offer.
