The Samsung LED 8000 delivering the pure thrill of 3D entertainment, connectivity that enhances your life, and visually stunning picture quality. Action leaps off the screen with advanced 3D technology, for a truly immersive viewing experience.

The Samsung produces a fine 3D experience in terms of depth, clarity and immersion and we appreciate the 2D->3D conversion, however we found the crosstalk to be a distracting annoyance to an otherwise exciting experience. We’ll produce a full review incorporating our  full menu of  2D performance tests once we determine whether the uniformity issue is limited to our review sample or is endemic to the design, so please stay tuned.

The C8000s are the only Samsung 3D LED models to have “Precision Dimming”, (commonly called as local dimming) and adds 240 Hz refresh and slim .9″ depth.Referable a panel uniformity issue in our factory loaner test unit, we limit this first look for its 3D features and performance.

What’s Local Dimming?

There are two major kinds of LED backlighting: Edge-lit and local dimming. Edge-lit displays are what they sound like—the LEDs are arranged in strips running along all four edges of the TV, like you can see in this gut shot from Cnet. A light guide directs the glowyness toward the center of the screen. The advantage of edge-lit displays is that they can get incredibly thin, are 40 percent more power-efficient than regular LCDs and are a bit cheaper than local-dimming TVs. But because they’re still shooting light indiscriminately across the LCD panel, they can’t pull off the black levels that a local dimming backlight setup can.

One thing that makes covering LCD TVs so interesting is that thd crystal pixels, and local dimming is when sections of the LED array are turned off or dimmed to help producee technology is always advancing and one innovation that might be the biggest in LCDs yet, is local dimming. But you’re probably wondering, what is it exactly? Well in non-edgelit LED LCDs TV, there’s an array of LED lights behind the liqui the deep blacks — like Kuro deep. But while this tech can produce very deep blacks and fantastic contrast, there’s a catch, it also create an artifact referred to as a halo around bright objects. Example: the two images above are of the opening scene of The Matrix (cops shining a flash light) it’s pretty easy to tell which is the plasma and which is the LED LCD with local dimming. Of course we don’t exactly watch movies with flash lights or star fields every night, so after the break are more pictures of a normal dark scene that also expose the artifact caused by local dimming (we have to point out that the camera makes it more drastic than it appears in reality). So while we wouldn’t buy an LCD without local dimming, there’s still a lot to look forward to in the next generation when the dimming is sure to become more local, and thus the artifact will be minimized. At the same time these advancements should help produce more detail in blacks, which is harder to notice at first, but just as annoying once you do.
