Sony has unveiled a gargantuan 84-inch 4K resolution LED TV, the XBR-84X900, with a gargantuan price tag to match. Retailing for $24,999, the flat screen is the company's largest to date, with a whopping 3840 x 2160-pixel resolution and passive 3D (another first for Sony), plus a 10-driver stereo speaker system. Additional features include SimulView (two-player gaming without split screens) and a large library of apps through the Sony Entertainment Network. Those with deep pockets can pre-order the TV now, with a ship date scheduled for November. Check it out in person now at Sony stores and select retailers.
