The multiplayer demos only support 3DTVs on consoles and Nvidia 3D Vision on PC.
It has been said on multiple occasions that the full game will support more but the actual list of supported 3D displays in the final game has not been published. So it is unknown at this time if you will be able to use your regular TV with anaglyph glasses (the good old red/blue glasses that work on any display)
In any case : glasses you get from the cinema (the ones that cost 1$ and which you are allowed to keep, not the ones you rent) require special 3D displays (circular polarised) : they will NEVER work on a regular 2DTV.
------------------------------
I would appreciate if someone from Crytek could publish an official list of supported 3D output formats.
I own non-hdmi1.4 3D displays and I would like to know if Crysis 2 will support them, and/or if Crytek would accept to support rare types of 3D displays if only a couple users ask for it.
