Toshiba Qosmio F755 Toshiba
Onboard webcam tracks your eyes to show you better 3-D
Glasses-free 3-D screens allow viewers to ditch the dorky shades, but with a trade-off: Images are sharp only in a narrow sweet spot; move, and the picture distorts. The Qosmio F755 adjusts its sweet spot as the viewer shifts. The 15.6-inch LCD directs left and right images to the corresponding eyes using a thinly striped overlay, known as a parallax barrier. A built-in webcam tracks the viewer's eyes and tells the graphics processor to shift the barrier microscopically to match any ticks in head position. $1,700
