Thx for the tips!
Problem: No output on 2nd screen. (mainly NVidia)
Solution:
Start NVidia configuration panel and go to manage 3D settings.
-NVidia 3D config panel won't show Avenue.exe in the 3D application list, also it won't when you press [add] and navigate to the folder, probably [C:\Program Files\Resolume Avenue 3 Beta rev990\], but when I started typing Avenue.exe it appeared in the dropdownmenu !!!
-Create a profile for Avenue.exe by following the steps gpvillamil described:
[set the Multi-Display/mixed-GPU acceleration to Compatibility Performance Mode]
That's it! Both Windowed and Fullscreen output on 2nd screen working!
Note !! For me, this solution only worked out with Omega driver.
[edit] hehehe.. crossed post.. Thx Edwin and Bart also for this workaraound!
