There are quality docks that work on displaylink. The dell D6000 is one example and we issue them out freely at work.
Most third party off brand docks will have higher failure rates. We see that with some anker docks that were usb-c+pd we use/had to source during the great supply chain snafu during covid. They worked in a pinch but aren’t reliable like a Lenovo or Dell dock. That’s less a displaylink thing and more a cheap dock thing.
