Well that was a short period before the next mess up.

1. Shutdown computer with lid closed.
2. Open lid and power on laptop
3. Leave the laptop display open and use all 3 screens
4. Start display support tool
5. reset debug logs
6. Start RDP to 8.1 machine full screen on main monitor
7. Change RDP to window so I can drag it from Main monitor to secondary
8. Try to drag it from laptop main monitor to secondary displaylink display
9. Black screen and Ethernet disconnect BLAH
10. Gather logs and take screenshot

Well that's enough on the left port for today. What caused this issue according to the logs?

Hardware and software the same as in the previous post #18. The only exception this time is the lid was open and all 3 screens were active.
