I have sx20 and i connected the first monitor to display and the second output to recorder , the first out is giving signal and it's OK but the second monitor not giving any signal to the recorder it's given only CISCO logo once i restart the codec however i configured the sx20 monitor dual .
Once i remove the cable from output 1 ( monitor 1 ) it give me signal on output 2 ( monitor 2 ) and when i return back output 1 it disappear again from output 2 .
On top of what Jens has posted about, because you're running dual display with a TC software endpoint, you might want to also take a look at the following selfview settings as well. It ill make the selfview show on the second display where the content is shown, this is because in TC6 software they changed how the selfview is displayed when dual screens are being used, it's not automatic like it use to be, they made it user configurable.
Video > Selfview > MonitorRole Video > Selfview > Fullscreen
The commands might be a little off, I'm not able to check a codec for sure, but they should be close enough.
