Thanks, Ryven, Sorry I didn't make this clear. The display wall I am using is an overlapping wall. That means two projectors are physically adjusted to be overlapping/edge blending. These projectors have built-in image processor to do edge blending.
In fact, I can start osgViewer using following parameter and manually drag/resize its window to span to the entire X screen with stereo. osgViewer --window 20 20 512 512 --stereo QUAD_BUFFER cow.osg So I guess osgViewer works no matter it's a one X screen or two X screens. What I am trying to know is, in my configuration, if it is X server's problem to prohibit default-to-be-maximum application to span the entire screen, or if it is osgViewer's problem to detect maximum screen resolution.
