LAS VEGAS--Among the oodles of new HDTVs Sony announced for 2011, the KDL-HX820 will be the second-most expensive after the flagship.
The main difference between the two series of LED-based LCD TVs is their backlighting schemes. While the XBR gets full-array local dimming, the step-down HX820 delivers local dmming from an edge-lit configuration--an arrangement we haven't liked as much in the past. On the other hand, edge-lit LEDs are generally slimmer than their full-array brethren.
The main differences between the HX820 and the step-down NX720 are processing related. the HX820 includes the higher-end X-Reality PRO Engine and MotionFlow 480 video processing (we assume the latter is the equivalent of 480Hz). We're not sure how much difference these step-ups will make, however.
Otherwise the two are very similar. For more information, refer to our
