# For Linux, a Nvidia 3D vision emitter "workaround" requires the DIN 3-pin connector found on the high end Quadros and [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses and emitter. The 3-pin DIN cable is difficult to find if you do not have one, and it is recommended that you splice your own. This author purchased a 3-pin mini-DIN connector here: [http://www.vetco.net/catalog/product_info.php?products_id=6588], spliced it onto a 2.5mm stereo audio cable like from here: [http://www.vetco.net/catalog/product_info.php?products_id=6952], using information adapted from this page explaining how to adapt connections for the older VESA standard for stereo here: [http://www.stereo3d.com/vesa3.htm] (it works quite well). The Figures on [https://forums.geforce.com/default/topic/411219/3d-vision/3d-vision-vesa-cable/7/] or [https://forums.geforce.com/default/topic/513899/3d-vision/link-nvidia-3d-vision-kit-with-dlp-display-projector-connection-problem-with-vesa-stereo-cable-ir-tr/] show details on connecting the plugs. Note that the 5V power line does ''not'' need to be connected as the receiver is powered by USB.

# The most affordable NVIDIA 3D Vision solution on Linux used to be a monitor with built-in IR emitter (for example BenQ XL2420TX or ASUS VG278HR), and a cheap Quadro, e.g. the K420 or FX380. The latter has a Dual-Link DVI (DVI-D) and a Displayport outlet, so can drive the stereo monitor, and an additional monitor. This solution avoids the USB/3-pin hassle altogether. See below for xorg.conf! GeForce cards (instead of Quadro) ''do not give openGL Quad Buffered Stereo'' on Linux (on Windows neither). Unfortunately, monitors with built-in IR emitter are seemingly no longer produced (2017).

# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] also has not changed for years. http://geizhals.eu/?cat=monlcd19wide now has a "inkl. 3D-emitter" attribute. This currently only returns the Asus 278HR which can only be bought in Poland, or through EBay.

# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] is not up-to-date; in particular, monitors with built-in emitter are no longer being produced (potentially can be bought on EBay or so). http://geizhals.eu/?cat=monlcd19wide has a "3D-fähig" (3D-capable) attribute.
 
# Cheap Quadros (e.g. K420) with DVI-I Dual-Link Connector (DVI-I DL / DVI-D) or DisplayPort work well. Make sure the card can do dual-link DVI if your monitor has only DVI-D input. Any card (including the "Windows only" ones!) [http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro listed] should work if a) it can do dual-link DVI if the monitor has only DVI-D input, and b) if the monitor has built-in emitter. The DisplayPort 1.2 (Quadro) to DisplayPort 1.2 (monitor) connection works well (e.g. with the BenQ XL2420TX).

# To connect a DVI-D monitor to ar Quadro with DisplayPort 1.2, you will need a Club-3D CAC-1051 active DisplayPort/Dual-Link DVI Adapter 330MHz (110 €: do not buy the cheaper 270 MHz model, it will not work because the bandwidth is too low for 1920x1080@120hz) or for cards with miniDisplay ports, the Club-3D CAC-1151 active miniDisplayPort/Dual-Link DVI Adapter 330MHz.
