Duh, I am an idiot, should have read more carefully.

If your system uses passive glasses (the non shuttering type) then the
problem is most likely in the setup of your display. If the display is
using sequential ("active") stereo from the Quadro (that's what I assume
since you are using quadbuffer) and converting that to passive, do check
for the presence of the synchronization signal. If you aren't using HDMI
1.4 (or newer) connection, you may have to connect an extra mini-DIN or a
USB cable somewhere. Some Quadro cards require buying of an extra bracket
with a connector for this (like this one:

)

If it is this display:

Then you may be actually out of luck. The DVI-D and DP 1.2 ports don't
support the synchronization signals required, AFAIK. You may want to
contact HP support about it and verify with them.
