Hi,
As a first point of call please check:
- You have the latest graphics drivers (for your PC) installed
- You have the latest DisplayLink drivers installed
If the issue is still seen, please 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
