You do not need a special TV to view 3D in Anaglyph (Red/Blue).  If you happen to have a 3DTV, it is designed for either Active or Passive display of 3D content.  If your 3DTV glasses require that you turn them on and off, you have an Active 3DTV.  If your glasses are polarized and don’t require powering on and off, then you have a Passive 3DTV. All 3DTVs and 2D TVs can display Anaglyph 3D content.
