# cheap Quadro cards with dual-link DVI-D or DisplayPort work well. Quadro 380, 400, 420 and 600 have been reported to work on CCP4BB. Make sure the card can do dual-link DVI if your monitor has only DVI input. Any card (including the "Windows only" ones!) listed at http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro should work if a) it can do dual-link DVI if the monitor has only DVI input, and b) if the monitor has built-in emitter. DisplayPort is fine with the BenQ XL2420TX.

[[Zalman Stereo]] is supported by [[Coot]]; no drivers or other software must be installed.


Using NVidia's 346.35 driver on RHEL/CentOS/SL 7, I changed /etc/X11/xorg.conf (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html) to have

For an example of how to configure xorg.conf, see old versions of this article.
 
Sometimes it is handy to configure two Desktops: one on a CRT monitor that can do stereo-graphics, and one on an LCD monitor for the more regular work, eg your refinement jobs with CCP4. For Nvidia cards you need to modify the xorg.conf file to have a section more or less like that:
 
<code>
Section "Monitor"
    Identifier    "Monitor0"
    VendorName    "Iiyama"
    ModelName      "Vision Master Pro 512"

Note that one can think this is rather silly to define two card, two monitors, two cards, and two screens.
However, that the only way I know that one monitor can be stereo-enabled and the other one not.
