GL_STEREO not supported, but it should be!

Hi all

I am new of the forum and not experienced with OpenGL programming. I have an issue with OpenGL while programming with Matlab and Python. I am quite desperate and hope that someone here could actually help me.

It looks like the extension GL_STEREO is not present/supported by my hardware, but I think it should be…!
My PC is equipped with Quadro K4000 and latest driver (361.91, OpenGL version should be 4.4 or 4.5).

I am actually trying to use the Nvidia 3D Vision kit from Matlab or Python, but so far it does not work properly because of this problem I suppose.

Thanks a lot for any hint!
