If I launch the nVidia control panel I can get to a pane that says "set up multiple displays" and on this I can select "configured independently from each other (Dualview)". If I select this then bring up the standard vista "display settings" dialog I can drag the monitor representations around to give either side by side or one on top the other orientation of the monitors. Launching osgViewer without any parameters gives a display which is spread over both monitors. In fact this is my normal desktop setup. The default OSG behaviour is usually quite annoying as models centre on the join between monitors so I modify this by setting the OSG_SCREEN environment variable to 0 in which case osgViewer only uses one of the monitors. So whatever the default setting is causes the OpenGL rendering context to be spread over both displays.
I have no idea what happens with more than two screens :-) Roger _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
