I can't say I'm an expert on the subject, but I'd assume you'd at least need a modern screen and a computer that supports it.
I don't think this is the same technology as the new modern 3D is, where the screen refreshes both sides separately, which I believe is the technology the new Nintedy 3DS use, as well as the new 3D-ready modern TV's.
Don't take my word for it though - as I said, I'm no expert. But WoW started support for 3D a few years ago, so I at least assume they didn't start supporting it before they started developing monitors and TV's for it.
