Vlad,

I just saw an active DP-HDMI Adapter

Is this what you wanted?

Betreff: Re: vmd-l: Quad buffered stereo from Quadro M4000 to HDMI monitor
Vlad,
  I just saw your more recent posting about driver problems caused by
conflicts between nouveau and the commercial NVIDIA drivers.
I assume that perhaps the problems with stereo below are/were closely
related to this?  Did correcting the NVIDIA driver installation solve the
issues with stereoscopic display as well?  
In general the nouveau driver is far behind where it would need to be to be
usable with VMD.  I doubt that the nouveau driver supports stereo at all, so
that may explain the issues below if there were remnants of the nouveau
driver on your system when you ran the
tests described below.   In any case, if you look at the /var/log/Xorg.0.log
files produced by the X server during startup, that would likely make it
clear which driver was loaded at the time, and problem(s) it had with the
display configuration.
Cheers,
  John Stone
