At this moment in time, Dell's latest drivers are indeed not the latest DisplayLink drivers in general. Nevertheless, for the sake of sanity I just installed the latest driver(s) from synaptics.com and still no displays. Drivers won't start, code 31 again. It's code 31 no matter which drivers I try! They won't start at all... I've attached new logs I collected just now. Thanks very much!

According to this DisplayLink knowledge base article --> https://support.displaylink.com/know...-on-windows-10 a 'Code 31' error can sometimes be caused by security software installed on the host computer (for example, anti-virus software):

"DEVICE MANAGER - ERROR CODE 31

There have been some instances of DisplayLink devices with a yellow "!" in device manager, and opening the properties shows that they have an error code 31. To resolve, please ensure your anti-virus or endpoint protection software is not blocking UMDF driver installation."

If you have any such software installed, if you temporarily remove the security software and attempt the DisplayLink driver installation again, does that help change the result?
