We are using graphics card NVidia Quadro 1000M and Nvidia driver version 302.10.
We are using Qt Quick 2.0(Qt5.0) and Qt3d which needs OpenGL.

What kind of graphics card and what kind of drivers are you using?  I think some dual-display graphics cards can't provide OpenGL acceleration on both monitors at the same time.

Do you need OpenGL for your application?  (or are you using Qt Quick, which needs it?)
