OpenGL Quadbuffer not working with second Monitor
Help!

Having trouble getting a two screen configuration to work with Geforce 3D vision when using a Quadro

Setup:
Quadro Fx3700 with stereo connector
Geforce 3D Vision glasses and emitter (latest drivers)
Samsung 2233rz + bog standard flat panel display

Everything runs fine with just the Samsung plugged in but as soon as I plug in a second, non 3D vision monitor the glasses can't sync. They sync up for a bit, then loose it, then come back.

If I stick a scope on the stereo connector it is clear why:

With one monitor plugged in the signal is a nice 60Hz square wave per eye. With the second monitor plugged in the signal is a superposition of a 60Hz signal and a slower signal. As the two signals go in and out of sync the glasses intermittently get a lock.

The glasses do sync if I don't use the stereo cable mode but then I get a flicker now and again which is too distracting (the system will be used for training).

Any suggestions appreciated (particularly from Nvidia Driver developers)

Thanks

If using force stereo set it off ,it might solve your problem.
Otherwise the two monitors must have the same frequency (if using the stereo connector).
With active glasses the two monitors must also be synchronized(genlock)
