I read the cnet review pasted below. Real world isn't quite as good as it's advertised stats:
quick aside for the geeks: The discrepancy between the Samsung's black levels showing a fully black screen vs. real program material was supported by further testing. For instance, the Samsung's black screen was immeasurable by our KM CS-200. However, when we looked at a standard checkerboard pattern--which includes both white and black, and so better represents actual program material--the Samsung's blacks were not only measurable, but lighter than the Sony's and the Pioneer's. We suspect the main culprit here is blooming (see below), where the bright white squares next to the darker ones spoiled that absolute black. Either way, these objective tests jibe with our subjective experience, which is that the Samsung gets extremely dark on full-black screens, but that performance doesn't translate to the very best black-level performance with most program material.
Back to Transformers: As the sun set on the tarmac after the mysterious chopper lands, we had a good opportunity to appreciate the Samsung's superb shadow detail. For example, we could make out the camo of the shadowed soldiers and details in the Decepticon's jet engine; it all looked quite natural yet packed with the punch only great contrast can deliver.
We did see one small fly in the black-level ointment, however. The LEDs produced what's known as "blooming," when a bright onscreen item exceeds its boundaries and brightens the dark areas immediately adjacent. When the Transformers title came up in a field of black, for example, or when Earth spun around to be cut off by the black letterbox bars, the black areas next to the lettering and the planet brightened in comparison to the other sets in the room, which exhibited no blooming. In most scenes, however, blooming was difficult to detect, especially outside the letterbox bars, and we never found it outright distracting except when we watched the set from off-angle. We also expected the Samsung, since its LEDs do vary in intensity, to fail our black-level retention test, but it passed with aplomb after calibration; the levels of black and near-black remained constant relative to one another regardless of the brightness of other areas of the screen (blooming notwithstanding).
Sounds like a pretty good TV but not for the price.
