Christian:
I don't know how Windows works but a problem that I had with my system is that the monitors (ASUS VG236H) have internal IR emitters. These interfere with the external emitter and destroy the stereo effects. (You see two images on the screen but they are not synched with the glasses, so you also just see two images when viewing through the glasses.) In Linux, you turn those off by specifying an option in the SCREEN section of xorg.conf:
Option "DisableBuiltin3DVisionEmitter" "True"
I learned of this by talking with the NVIDIA engineers. I never found it in their documentation. Perhaps you are fighting the same problem here. John, I don't know how to translate this to Windows, perhaps you can provide a clue.

Subject: Re: vmd-l: Fwd: VMD Stereo does not work Quadbufferd

Dear John !

Yes it is strange the transmitter of the stereo signal just does not turn on , if i start a simple 3d game in the background i can see vmd stereo and the transmitt3r is on,
before i can tell the transmitter was off but the glasses showed nothing stereop just the double pictures from stereo which you can see without glasses.

I think the problem is that it need a special signal from the application so the transmitter switches to on.
Maybe I defined vmd not as a 3d application.
Is the name vmd or vmd_??? i saw that vmd is a script which calls vmd_??? and maybe i should define this app. name name as a 3d application

thank you

Christian,
This is quite strange. VMD is reporting that you have stereo, so I would
expect that when you turn it on, it should work. Which stereo mode do you
have set in your Windows driver?

Cheers,
