| The Bottom Line | It costs a mint, but Samsung's local dimming, LED-based UNB8500 series delivers the best picture quality of any LCD we've tested. | The Samsung UND8000 TV delivers best-in-class looks and features, but its picture quality--thanks to uneven screen uniformity--is ultimately not as good as that of many less expensive models. | With flagship-level picture quality for a midlevel price, the Panasonic ST50 series sets the value standard among videophile-grade TVs. | One of the best-performing LED-based LCDs we've ever tested, the expensive local-dimming Sony XBR-HX929 competes well with the top plasmas. | The overpriced Sharp Elite LED-based LCD produces the best overall picture quality of any TV we've reviewed since 2008. |
