How quickly things change. Just a couple of months ago, the likes of Sharp and LG were vying for bragging rights over the largest TVs at the CES show in Las Vegas, with sets around 108 and 102 inches. Now, Italy's Tecnovision has dwarfed those models with what it's understandably billing as "the world's largest television" on display at CeBIT in Germany, a 205-inch HDTV--practically big enough, Tech Digest says, to fill an entire wall. There's no information on specs or pricing, but we suspect that its name alone, "Luxio," is an indication that K-mart won't be having a blue-light special on this item anytime soon.
