FrontRunners: Screen Star
December will mark the arrival of the Panasonic TH103PZ600U (www.panasonic.com), the world’s largest plasma television. The unit will feature a 103-inch-diagonal screen, about as large as a queen-size mattress. Because the 400-pound, $70,000 system has some 2 million pixels, about twice the number used by smaller screens, the size does not compromise clarity. . . .
