Summary: It costs a mint, but Samsung's local dimming, LED-based UNB8500 series delivers the best picture quality of any LCD we've tested.
Pros: Deeper black levels than any HDTV available aside from Pioneer Kuro; solid shadow detail; reduced blooming compared with other local dimming LED-based LCDs; accurate, highly saturated color; excellent video processing with adjustable dejudder; numerous picture adjustments; extensive interactive features including Yahoo widgets; beautiful styling with 1.6-inch deep panel; extremely energy efficient.
Cons: Expensive; poor off-angle viewing; some blooming effects; benefits of 240Hz difficult to discern; glossy screen reflects ambient light.
Excerpt: Samsung, it appears, is going LED in a big way. Thirteen of its LCD sets in the 6, 7, and 8 Series use LEDs for back-lighting instead of CCFLs (cold cathode fluorescent lights), which until recently have been nearly universal in flat-panel LCD HDTVs.
