Beta 2.1 Driver - Menu bar issue?
 

Since I installed OSX Mavericks and the Display link 2.1 beta driver I noticed that the menubar in OSX shows on both monitors. Before it would only show on the primary monitor. it's as if it's duplicating the menubar only on the 2nd monitor. The dock stays on the primary monitor. Has anyone else seen this?

Normal behavior for mavericks. Each display has its ow. Menu bar

As gilesmartin said this is a feature of Mavericks, nothing to do with DisplayLink.
Each display has it's own menu bar now and the dock can move between monitors.

You'd see exactly the same behaviour if you had a single external monitor connected via the mini-displayport when on Mavericks.

In my case, I have one via mini-displayport and one via a DisplayLink adapter, so I would have three menu bars, one on each screen.

oh wow! thanks, I guess I missed that! :)
