Hi Dieter, The View::setUpViewAcrossAllScreens() is set up to detect all the screens and open up windows with the appropriate projection and view matrices for a power wall. By default osgviewer should use this option. Have you tried this on your system? It'd be interest to here how this works out. In theory:
osgviewer mymodel.osg Should just work on your system right out of the box with no need for mods. Robert.
