 To configure the P6000 for 3D stereo, bring up the NVIDIA Control Panel, and go the the "Manage 3D Settings" section. In there, "Stereo Enabled" must be on, and the "Stereo Type" must be for the 3-pin DIN (//not// 3-pin DIN for 3D Vision) for our setup.  There is a separate "Stereographic 3D" settings section that has no effect for Chimera/ChimeraX -- it is primarily for applications that do fullscreen 3D stereo with Direct3D (e.g., games).
 
-Another critical setting is whether Windows considers the projector or the flat-panel the primary display, an option in Windows Display Settings.  For several months it worked only if the projector was the primary display.  After moving the machine stereo stopped working and we fixed it by making the flat panel the primary display.  We do not know what changed -- perhaps it is important which of the P6000 video outputs is used.  The current configuration has the projector using DVI output, and flat-panel using the first (closest to motherboard) Display Port output.  The symptom when it is not working is either that 1) only the left eye image is rendered, or 2) both left and right eyes are rendered by there is no IR signal.  The following day stereo no longer works unless the flat-panel is unplugged.  Although we had it reliably working with the projector as the primary display for 5 months using Nvidia 391.58 driver (May 2018), we are currently not able to reproduce that.  This appears to be a graphics driver bug when using two displays where there is no IR output.  Possibly it depends on which output Display Port connector on the Quadro P6000 the non-stereo display is connected to.

Possibly it depends on which output Display Port connector on the Quadro P6000 the non-stereo display is connected to.  After using stereo with just the projector connected, then logging out, plugging in the flat panel into Display Port output 2, and logging in to an admin account, stereo works again.  Logging out and logging in to a standard user account stereo still works.  Perhaps it only works if the flat panel is plugged into the second display port output, or perhaps logging out is needed.
