| Bottom line | The Sony HX850 is a smart-looking Smart TV with sparkling picture quality, making it a front-runner for plasma-phobic videophiles. | Very good picture quality and an extremely aggressive price make the Vizio M3D0KD one of the best
LED TV values on the market. | With good picture quality and great pricing, the Sharp LC-LE640U series makes a strong case for mainstream TV shoppers who want to go bigger. | Although it hits plenty of high points, the Samsung UNES8000
LED TV cannot ultimately justify its high price. | The Vizio CinemaWide TV embodies an intriguing idea, and it's quite a fun way to watch movies without black bars, but its performance isn't commensurate with the price. |
