Hi,
What graphics card are you using? Did you follow the instructions on the Trivisio website?

It seems like the goggles use frame-sequential stereo. This needs to be handled through your graphics card. nVidia provides a special stereo driver for these types of setups. The link should explain how to set this up.
Once installed, all you need to do in Vizard is enable fullscreen with viz.go(viz.FULLSCREEN)
