It is very much dependent on the quality of information our driver receives from the desktop environment. We have seen differences in performance between Unity, which is used by default on Ubuntu and other environments like GNOME Shell or KDE's Plasma. This is also getting more visible with the number of extra screens you add, and is also dependent on the platform you installed the O/S on.

If the desktop environment is not optimised to notify just the parts of the screen that has changed, and sends all pixels again instead, this will impact DisplayLink performance, as we will have more data to send to our device.

I'm going to close this thread to new posts, as it looks to be turning into a support thread for multiple issues.

For feedback on the Ubuntu driver for USB 3.0 devices, please start new threads in this forum.

Thanks
