Duplicating screens

[elpetto]

Hi guys,
I work with the HMD Oculus Rift and a second Display (Monitor). What I want is that the HMD shows the virtual reality and the second Monitor as well. But when using the Oculus Rift system, Vizard splits the Screen in the middle in two pictures (for the left and right eye, see uploaded picture). Now the problem, if I simply just duplicate the monitors via Windows the second Monitor also shows the split screen modus (like the Oculus Rift).
So is there a chance that the HMD shows the virtual reality in the split screen mode and the extended monitor as a usual non split screen mode?

Thanks a lot for helping,
Patrick

hmd = oculus.Rift()
sensor = hmd.getSensor()
viz.link(hmd.getSensor(), viz.MainView)

viz.go()
scene = viz.addChild('dojo.osgb')
viz.move([0,-1,-5])
