Describes the characteristics of a graphics destination such as monitor. In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of the Screen objects are relative to the Screen.primary.

For example: 

Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();

//set Stage boundaries to visible bounds of the main screen
stage.setX(primaryScreenBounds.getMinX());
stage.setY(primaryScreenBounds.getMinY());
stage.setWidth(primaryScreenBounds.getWidth());
stage.setHeight(primaryScreenBounds.getHeight());

stage.show();
