Unstable Monitors on ThinkPad Universal USB-C with X380 Yoga

2021-10-21, 14:10 PM

I am trying to connect my ThinkPad Universal USB-C dock to my X380 Yoga laptop and it will not stay connected.  I have a USB keyboard and two monitors connected to the dock and when I plug it into the laptop it will show the monitors working as extended desktops for a few minutes then it will start disconnecting and sending everything back to my laptop screen only, then it will reconnect and move things back to the monitors and so on.  I've tried unplugging and replugging everything and I tried downloading the most updated drivers with reboot as well.  Sometimes I can get up to 30 minutes of it working, but then it will revert back.  


I also disconnected the monitors and keyboard and just tried to use the dock as a power source, but it was doing the same disconnect/reconnect where it would make my laptop screen flicker in and out.  


Appreciate any help you all have!

Hello SB_42!

Welcome to community forums!


Can you provide the exact model of the dock, OS version on the laptop, and the BIOS version?

Have you tried installing the driver/firmware of the dock?


Try manually installing the GPU driver here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x380-yoga/downloads/driver-list/component?name=Graphics%20Processing%20Units%20%28GPU%29%20and%20Server-AI%20Accelerators


Update us on how it goes.
