Sony's foray into the 3-D gaming space gets a running start with its 24-in. (61 cm) 3-D-capable monitor. Priced at a reasonable $500, the display works not only with PlayStation consoles for 3-D gaming but also with other compatible 3-D sources like cable boxes and PCs. But the coolest feature of Sony's display is SimulView, which lets two players go head to head on the same screen by showing each player a separate picture at the same time.
