Hi Carlo,
Thanks very much for your reply,
Their download page (
http://www.cablematters.com/cs-Downloads.aspx) links directly to the
http://displaylink.com/support/mac_downloads.php driver download page.
Which driver should I be using with my hardware? I presumed the 2.3 Beta should be ok?
Im wondering if perhaps mine is an older USB3 device which actually doesnt use the DisplayLink driver.
