A 3D-Capable Display (3D HDTV, 3D Monitor, or Projector)
There’s no way around it. If you want to watch 3D at home you will need to buy a 3D-capable display. These 3D-enabled Television (3D HDTV) includes LCD, Plasma, LED and DLP Televisions, as well as DLP and LCD-type video projectors or 3D-enabled Video Projector.
What makes them 3D capable is that they have higher processing power than older models (the regular TV sets) and higher Hz (120Hz at least!) as they need to display two images double the speed ! One image for each eye to create a 3D effect. Do not buy a TV that has less than 120Hz, it will be too slow processing the images and you will probably get an headache because you will notice the image flickering while trying to show you a 3D movie..

The older technology that will probably fade away in the coming year is the 3D overlapping images, where two images are displayed at once on the screen. This 3D technology needs the Passive Glasses each lens is polarized so that it can see only one of the two overlapping images. The main drawback of this technology is that viewers will need to sit directly in front of the display to get the full 3D effect.
Active liquid crystal shutter glasses quickly block each eye in sequence to ensure that each eye only sees the corresponding image on the 3D HDTV. Those are not the paper cheap 3D glasses you know, the shutter active 3D glasses cost more, and are battery activated.
