Dear Chimera, Sorry - Specification - We naturally meant: CHIMERA to WORK with "stereo viz on new samsung "3D" LCD and quadro card"
Dear Chimera,
We recently got a mail on instruction to install correct parameters to get VMD-L to work:
"vmd-l: help with stereo viz on new samsung "3D" LCD and quadro card"
Now we ask, do you have any suggestions to get "Samsung "3D" LCD and quadro card" and to get CHIMERA work not only for:
1. Linux (Ubuntu) with "quadro card"
but also and on:
2. MacPro/Mavericks with "a quadro card"
We thank you in advance
Cheers Peter et al.

[Hide Quoted Text] Carlos, 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 that's separate from the issue of having the Quadro's stereo sync and other features working.
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 for, as seen on a couple of our machines: (**) NVIDIA(1): Option "Stereo" "10" (**) NVIDIA(1): Option "ForceStereoFlipping" "true"
