Hello Mario, I think what you are seeing is normal behavior because you have two graphic cards involved in your setup.
The rendering can only happen in one GPU and usually if a second graphics cards is involved the final window contented is (partly) moved from one graphics card to the other. If the window moves over to the second graphics card, the application is responsible for moving resources (like OpenGL textures) to the other GPU in order to run on that GPU too. I am not sure about QuartzComposer, but it could be that QC only uses the graphics card where the main menu bar is located and never let you change that when running (also not moving window content partly to the other graphics card) QC Visualizer is an app for running the same composition file on two different computers synchronized via the network. I think this won't help you too. I guess if you are authoring in QuartzComposer Editor you are bound to two screens. As fare as I know for playback on more than two screens, you have to have multiple computers running QC Visualizer. best, Achim Breidenbach Boinx Software Ltd.
