The GraphicsContext::Traits structure is used to control how the graphics window is created, and in it's default state the display and screen settings (see osg::GraphicsContext::ScreenIndentifier) are 0:0. To override this default one needs to explictly call readDISPLAY() which reads the DISPLAY env variable to set the display and screen number. Now the osgView::setUpView*() methods all call readDISPLAY(), but if the example does use on of these methods, and instead creates the GraphicsWindow it requires directly use GraphicsContext::Traits without calling the readDISPLAY then it won't pick up your settings of this variable, so you'll get different behavior.
