Well, I think you are using the closed source Nvidia drive and if it is the case then there is no solution at all (
https://support.displaylink.com/know...rticles/641668). As they don't bother to fix this although they keep saying this is in the backlog.
In many cases, you can switch back to the open-source driver as they have suggested already, but if you plan to use CUDA then the best way to move forward is forgetting about DisplayLink completely.
