I purchased 2 x Plugable UGA-2K-A USB 2.0 adapters to run two additional monitors on my new 2011 Macbook Pro 15". I have a primary display running over thunderbolt/display port connector (for faster video), and that display offers “Rotation” option. The two monitors (20" and 24") which I’m running over UGA-2K-A do not offer the “Rotation” option under Displays menu.
I have installed the latest available drivers from DisplayLink (1.6 - 27 April 2011), and have tried their suggestion (http://www.displaylink.com/support/ti…) to use Command+Option keys when selecting Displays without success.
The adapters work fine in landscape layout, and quality is good. Even running them through Plugable 7-port USB hub works great. But I need to be able to rotate the monitors to Portrait layout. Any help would be greatly appreciated!
