Buying a 3D HDTV today means choosing between two different types of 3D technology. Which is the better way to watch?
Glasses-free 3D is still a long way off, so if you want to watch 3D at home today, you need to choose between two types of 3D HDTV, along with two different flavors of 3D glasses. Active shutter glasses use electronic shutters to sync the eyes to two different pictures on the screen to create a 3D effect. Passive glasses use polarized lenses to separate the pictures to direct them to each eye. Each has its advantages and weaknesses, which we'll outline below to help determine which 3D technology is right for you.
