Thanks for your report. We are trying to reproduce this issue. Does the problem happen at every restart or sleep/wakeup? If you are able to reproduce the issue easily, could you please download the new debug tool here
http://www.displaylink.com/support/ticket.php?id=269 and post the output file?. Switch first the log verbosity of the driver to DEBUG from the advanced menu (unplug and replug the adapter) , try to reproduce the issue and collect the information. Switch back the log verbosity to Info when fished. Thanks
