Slab problem with Geforce 7600 GS in dualview mode

hi all. I would truly appreciate help on this one- is it a hardware incompatibility? is my hardware/software malfunctioning? am I stupidly overlooking something? any ideas would be welcome…
I recently bought a new geforce 7600 gs video card. Everything is fine and dandy, except for one probelm which occurs only when using dualview with the second monitor as a fullscreen window output for my patch (which happens to be something I do frequently..). The video plays fine in the fullscreen monitor, until I put a slab in the processing chain- that’s when it all goes black. Nothing else gets that response- not using vj software with dualview fullscreen ouput + fx, such as resolume or neuromixer, nor using jitter patches with and without opengl contexts, all which work fine. only slab doesn’t render for some reason.
In one test, I slowly dragged the output window from monitor 1 to monitor 2. The slab actually kept working until the last pixel of the window has moved to the second monitor. Then it all went black. again.
It also works fine in “horizontal span” mode. but that’s no real comfort.
any and all input on this would be appreciated.

The only things I can recommend is trying to update your NVidia
Driver, try Jitter 1.6.3b1, and try modifying some of the settings in
the NVidia driver control panel and/or the windows HW acceleration
control panel. I’ve been unable to reproduce this issue on an NVidia
6800 or 7300 with Jitter 1.6.2 or later on XP.

There is a known issue of this happening with a 7950 GX2 (dual GPU),
but even with dual 7300s, I couldn’t reproduce similar.

If you discover anything specific to your setup to fix the problem,
please let the list know.

Hello,

I have almost the same issue (no need for fullscreen), with a nvidia
7600 GT AGP in dual view mode.

I have changed the 3D parameter settings within the Nvidia Control panel to :

“many graphic card acceleration” : “one display performance” instead
of “multi display performance” (I’m not sure about the exact terms).

It works, exept that only the main monitor got the graphic acceleration.

thanks jkc and bertrand. I tried changing the 3d settings like bertrand suggested, and it gave me something different indeed- now the window isn’t black, but rather shows a frozen still image of the video playing. couldn’t get any further than that though. also I noticed while checking on this, that the fps from both slab tests- cpu and gpu- is the same- about 10-13 fps. The cpu load i sdifferent though- about 80-90 for the cpu version, about 30 for the gpu test. still stumped. next i guess I’ll need to try the upgrade I’ve postponed for a while.
Thanks,
