NVIDIA Quadro M5000 disactivates second 3D screen under Red Hat Linux 7.2

Hi NVIDIA team,

Could you please help me with the following problem?

OUR REFERENCE
Our old reference graphics card NVIDIA Quadro K5200 (2 * DVI, 2*DP) supports 2 * 3D monitors when connected to both the DVI ports, or DVI and DP ports

THE PROBLEM
The newer graphics card M5000 (1DVI 4DP) appears not to support 2 * 3D monitors, 1 connected to the DVI port and 1 connected to the DP port
The M5000 appears to lose the mode information when I change the stereo option in xorg.conf config from “0” to “10”
The Error message from xrandr is “Output DP-7 is not disconnected but has no modes”
As a result the second 3D screen which is connected to the DP port is disabled and goes into sleep mode. This is true for both the NVIDIA 3D Vision ready screens.

THE EXCEPTION
However, if I replace the second screen by a much older 2D screen (Philips / Eizo) it works correctly.

DETAILS
PC : HP Z840 with a NVIDIA Quardo M5000
2 * NVIDIA 3D Vision ready screens: ASUS VG278HE or BenQ XL2720Z
Operating System: Linux Red Hat 7.2 64bit
KDE: 4.10.5 with KScreen2 deactivated to allow stereo

I will attach the following files
