I have just purchased the full version of ArraySync but I'm having issues where my Retina MBP and new Mac Pro will not output video to the external (Non Apple) Displays. Any ideas as to what may be causing this issue?

I'm doing some testing with trial version of ArraySync to make sure that this will work for my company. However, I am having issues with getting video to play on the external screen which is attached to my Retina MBP.

Any ideas?
