Do I need a 3D tv to have 3D pc? my graphic card supports 3D , I need the glasses, but do I need a 3D tv also?
If you are talking about 'passive 3D' then yes because you need a special screen that is able to simultaneously show 2 different images. Regular Tvs can't do that. you'll need both the tv and glasses
You need to have 3D TV so as to have 3D PC. This is because the particular device that you have is supported by a 3D monitor. Read more details at http://susana-s.hubpages.com/hub/3d-ready-pc.
