I have a T470 20HD running Windows 10 Pro. Both the operating system and all Lenovo updates have been applied.
Attached to this is a Plugable-brand USB3 dual HDMI docking station that's been driving a pair of Dell SE2417HG(HDMI2) screens, a wired keyboard & mouse, and a USB headset.
Or did, until I did the Integrated Firmware of Thunderbolt Function 126.96.36.199-N1QTF16W update, at which point it now only drives a single screen. Windows sees both displays but now can't use one. I've tested both displays and they work fine otherwise, and if I unplug one display the dock will "fail over" to the other display without an issue.
Is there a way to roll back this firmware update, or am I basically out of luck?

Welcome to the Community Forums.
We have found a previous firmware version of the Thunderbolt. You can download it here, https://download.lenovo.com/pccbbs/mobiles/n1qth05w.exe. Try to install it,
