Black Screen issue.
After a Windows Update roleout (with drivers) on about 140 Lenovo Thinkpads T480S/T490S an error occurs on about 8-10 laptops where monitors connected to USB-C docking station (40AS and 40A9) suddenly turns off.
2 weeks later and many hours of troubleshoot with/without Lenovo support we finally had a breaktrough with some 3 parts USB-C cables. Specs:
USB Power Delivery (5 A, 100 W), flettet, 10 Gbps data rate
DELTACO USBC-1412M - USB Type-C kabel - 1 m
We found a way to get the monitors to work while connected to the Lenovo Dock using this cable connected to the secondary USB-C port/Thunderbolt 3
I need a vacation after this troubleshoot :-)
I hope this video will help if you are experiencing the same issue.
