Hi,

I am on a 2012 27"iMac. I have a second monitor connected via USB and Displaylink. When I was on Maverick everything ran fine.

After updating to Yosemite itunes refuses to play HDCp protected content even on the main iMac screen. Gives me an error message "Display is not authorized"...Installing the latest Display link drivers (2.3) hasn't helped.


When I was on Maverick I have watched the same movie on the main display without any problem.

When I disconnect the second monitor iTunes plays the movie without a problem.


Please help.

Is there at least a way to shut down the drivers until the next system start, so I don"t have to disconnect the second monitor very time I want to watch some itunes movies?



PS:and a another anoying thing is that OS X don"t keep my resolution setting in the monitor setup menu: after every system start it returns to the max. resolution...
