Hi amnon,
I'm sorry to hear it's not currently working for you. Could you please run our support tool and attach the resulting zip file in this thread? The tool is available here:
http://displaylink.com/support/sla.php?fileid=109 but it would be good if you could also enable the Advanced Logging option…
* Click Advanced Options
* Turn on Advanced DisplayLink Logging
* Click Advanced Options
* Click Gather Support Information
Thanks,
Paul
