With LG's Dual Play enabled and the special Dual Play glasses, the company says players see two discreet, full-screen images, as opposed to the traditional split screen. Sony's flawed PlayStation 3D display performed the same function but required more expensive active glasses and only worked with a couple of PS3 games. Be respectful, keep it civil and stay on topic.

When users strap on polarized glasses to view a 3D film, they're already receiving two different images that are being displayed at the same time on a television or movie screen. Each image has been polarized using a special filter, and this filter orients each image's waves of light in a specific direction.

As for the glasses, the two lenses allow light waves to enter if they're oriented in the same direction as each lens's polarized filter: Horizontal waves for one eyeball and vertical waves for the other eyeball, for example. When viewers' brains go to process the two different images coming in at the same time, they are fooled into perceiving depth that isn't actually there. LG's Dual Play technology is kind of like telling two viewers to pop out the lenses on their polarized glasses and exchange them to create matched pairs.

Each individual user loses the ability to create a three-dimensional image , as it were, but both of a user's eyeballs will now receive light waves that have been oriented in a single direction. In other words, a person gets picture A and cannot see picture B, while their gaming competitor can see picture B and not A.
