Dear Chimera,

Sorry - Specification -  We naturally meant:

CHIMERA to WORK with "stereo viz on new samsung "3D" LCD and quadro card"

>   Ah, I had missed the startup message you included when I read
> your first note.  All of the VMD stereo modes other than "QuadBuffered"
> are implemented by rendering code within VMD itself, and they do not
> depend on the graphics driver or any special hardware capabilities.
> So, the fact that you are able to use the "SideBySide" or other modes
> just indicates that your TV can work with the VMD-supplied mode, but

> The VMD "QuadBuffered" stereo mode relies entirely on the GPU and
> its driver for stereoscopic display.  This is the best mode to use
> if you want the IR or RF stereo emitter to remain in proper sync with
> the displayed images, but it requires that the GPU drivers and windowing
> system be configured correctly, and that the GPU and driver will actually
> support the target display.  If you're running on Linux, then the thing
> to do is to check the contents of /var/log/Xorg.0.log and look for
> the word "Stereo".  Here's an example of the kinds of output you're looking
