Hi There, to build a power wall without a blending zone, you should create 2 screens (and update your server layout) in xorg.conf, that way osgviewer will span across all screens automatically. to have a blending zone you can create 2 windows (one in each screen), and adjust the projection of each camera/graphicscontext, check osgwindows.cpp example
