Well i've never used a 3D monitor before so i'm not sure. I don't even know if content is always 3D or if it has to be specifically made to display 3D content.
The 3D part - I think it all depends on which GPU you have, as well as which 3D display you have as well and obviously the content matters.
I would suggest reading this:http://www.3dmovielist.com/3dhdtvs.html
As well as googling for more information.
