I recently upgraded to a new laptop 20QT005PUS Lenovo ThinkPad P1 (2nd Gen) and new docking station 40AN0170US Lenovo ThinkPad Thunderbolt 3. When I install fences the third monitor goes black (after reboot) and will not come back on. I have got the monitor back by uninstalling fences. I have start10 and Groupy installed and they work fine. I have used fences on my previous laptop with the same 3 monitor setup with no issues and also windows 10. I am using the same 3 monitors so it seems to be an issue with the fences app and the dock.
