Hi,
Do you have another video cable you can try to connect the dock to the monitor? It's possible that the video cable is preventing the monitor's EDID from being read correctly hence the limited mode choice.
Regarding the corruption can you attach the output of this tool:
http://www.displaylink.com/support/ticket.php?id=269
Once downloaded, please run it and select "Gather Support Information"
When you reply please select "Manage Attachments" from the "Additional Options" section below.
From there select Upload and navigate to the output of the tool which will be in a folder called "DisplayLink Support Files" on your desktop.
Thanks,
James
