Hi,
I looked up the specs for your device (below) and it seems like you really need 'vertical split' stereo, which is the most common stereo mode.
You will NOT need any stereo features enabled with your graphics card, but simply you need to make sure your graphics card outputs spanned over two screens.
Follow the instructions at
http://www.worldviz.com/support/hardware_faqs.html
to set up your graphics card.
Now when you run a Vizard program and start it with viz.go(viz.STEREO | viz.FULLSCREEN | viz.HMD) then it should render two views and one should show up on the left screen (if you connect a screen) and one should show up on the right screen.
You can switch the Vizard rendering window between fullscreen and small with the F2 key.
Now if the HMD is connected correctly, you should see stereo.
Hope that helps.
Matthias
