ThinkPad Pro Docking Station - Type 40AH - External Monitor Not Working with V3.3.1 Update

2019-11-01, 20:05 PM

We recently update the ThinkPad Pro Docking Station Firmware to V3.3.1 

We are not able to connect the monitors after a few minutes.   When it eventually connects the screens are shifted to the left with a Black Bar on the Right Hand and Purple Line on the Edge  of Screen. 

Monitors with issues are LG Flatron W2242 TQ with 22 inch 1680 X 1050. 

Other 1080p monitors are working as expected. 

We are looking at how to rollback to the previous firmware version

Hi OCAS!

 

Welcome to our forums community.

 

Base on the website, there is a recent version of 3.7.3 of the firmware of the docking station. You can download it here: https://pcsupport.lenovo.com/us/en/products/accessory/docks/thinkpad-pro-docking-station/40ah/downloads/driver-list/component?name=Advanced%20Firmware. To make sure that everything is up to date, run the update through the Vantage app. Install all detected updates. Let us know if it works for you.

Did you ever find a solution for this?  We have the exact same issue with the same model LG monitors.  It is still an issue with the latest firmware.  We've opened multiple support tickets with both premier and regular support, and they have been less then helpful. There must be a way to apply old firmware. No one in support seems to want to take ownership and follow this through, which is really disappointing.

So a year later, and support has been clueless on this.  We're now faced with having to purchase dozens of new monitors as we upgrade laptops, over a firmware issue.  Docks I've confirmed with the problem are the Pro Docking Station, USB-C Gen 2 docking station, and Thunderbolt 3 docking station.  Disappointing to say the least.
