Stereo inversion on NVidia Quadro4 750 XGL

Hi,

I have just installed a brand new NVidia Quadro4 750 XGL card on my Dell
Dimension 8200 (Pentium 4, 2.53GHz, 2GB RAM)(Dell P1110 monitor) and I'm
trying to get a clean stereo image through OpenGL without much success. I
succeed in turning on the hardware stereo (through OpenGL) and I can even
see the image in 3D (using NUvision emitter + goggles). However, the problem
is that no matter what settings I use and no matter what 3D program I use,
there's a constant and very annoying Stereo inversion every 1-2 secs (the
image in front goes to the back and vice-versa). I have tried practically
all the settings, and all resolutions/refresh rates (all the way up to
144MHz refresh rate) but the problem never changes (with slower refresh
rates there's also flicker). Any ideas on what's causing this?

Thanks,

Alex
