Default No Video Signals - Dell D3100 - High Sierra

I have a Macbook Pro with touch bar and 2 external monitors connected to Dell Dock D3100. I had High Sierra and Windows 10 installed on my MacBook. Everything worked fine. All two external monitors work great. Last week, my Macbook Pro had a problem with the keyboard and I sent it out to Apple for repair. The Macbook came back fresh and formatted, so I had to reinstalled High Sierra, Windows 10, and DisplayLink drivers. For some reasons, my two external monitors are not working now with High Sierra (it works well with Windows 10). My external keyboard and mouse connected to my Dell docking is still working fine.

I tried to reinstall and uninstall DisplayLink drivers many times. It does not seem to help. I checked the system and here is what I found. I would greatly appreciate it, if you can kindly advise. Thanks!
