with great hope, I downloaded 4.3 beta 3 on my 2011 MacBook pro yesterday.
Tried to follow the instruction, but no popup window to ask for airPlay security. I managed to manually add the DisplayLinkUserAgent to the Accessibility, still, no airPlay icon, my hp 22cwa is
not detected, invisible in System Preferences > Displays...
With 4.1, at least I can do mirroring... there seem to be other 2011 MacBook pro complaints regarding 4.3 beta, wondering if this version has some incompatibility issues?
DisplayLink dev, is there anything I can provide to help you debug this scenario? Or anybody has any suggestion on how to fix/workaround this?

[update] Problem Resolved!
Turns out my non-detection problem is related to a faulty USB hub plug. All is well now. Good job DisplayLink!
