One player wears a set of polarized 3D glasses with two left eye lenses and the other player wears a set with two right eye lenses. That allows each player to see their own section of the game full screen, but only in 2D.

The TVs can toggle between a traditional split screen view, or the Dual Play view which, without 3D glasses, looks confusing as two screens are stacked on top of each other.

Dual Play isn't a new idea. At the E3 game conference earlier this year , though the display measured just 24 inches. Another difference between the Sony and LG products is that LG's uses cheaper polarized glasses, while Sony's model uses more expensive active shutter glasses.
