Ghosting with Nvidia 3d vision

[Trevor]

Hello, we are having a problem with severe ghosting using Nvidia's 3D vision kit. We are using a Quadro FX 570 and a Samsung SyncMaster 2233. The driver is configured correctly and we get stereo 3D in vizard using viz.go(viz.QUAD_BUFFER|viz.FULLSCREEN). The problem is that the individual stereo images are partially visible though the glasses, thus creating two ghost images of the object next to the converged image.
We have tried to change the background color, texture, stereo vs non-stereo, etc, but to no avail. Darker backgrounds appear to minimize the ghosting somewhat but not significantly.
Is there a way to adjust the depth of the image in Vizard? It seems that decreasing the distance between the L and R stereo images would minimize the ghosting. Any input would be greatly appreciated, thanks.
