Sharp Quattron LC-LE847U series review: Extra yellow pixel isn't worth extra dough

Review Sections

Connectivity: I have no complaints on this front. Four HDMI ports is plenty, and the analog connections (one component, two composite, one VGA for computers) are as complete as I'd expect. A pair of USB ports, one facing the side and one the bottom, round out the package.

Picture quality
Like many high-end LED TVs we've tested this year, the Sharp LC-LE847U didn't produce picture quality commensurate with its price. In its favor, it was able to maintain fidelity in bright lighting situations, color in bright areas was OK, and the extra yellow pixel of Quattron didn't make color accuracy worse after proper adjustment.

On the other side of the ledger, that fidelity isn't great, falling short of what you get from many less expensive sets like the Vizio E601i-A3 and especially Sharp's own entry-level LC-LE640U, which performs very well. Lighter black levels, lack of punch, and bluish discoloration, especially in dark areas, were the main culprits.

Black level: The LE847U struggled in this important picture-quality category. During the nighttime sailing sequence from chapter 5 of "Pirates of the Caribbean: At World's End," (29:20 and later), its shadows and letterbox bars looked about the same as the 60-inch Vizio's and more washed-out than on any of the others, including the Sharp LE640U. Those lighter blacks combined with relatively dim highlights, for example in the moonlit faces of Elizabeth Swann (29:42) and Will Turner (29:52), for a picture with less oomph and dynamic range than any of the others.

The LE847U didn't evince the same kind of "crushing," where deep shadowy areas (like Swann and Turner's tunics) disappear into the murk, that was evident on the 65-inch Vizio, but its shadow detail was still more difficult to make out than on the other sets. The folds in the characters' tops and the edges of their faces showed less definition and impact.

Color accuracy: In brighter scenes, such as when the crew gets washed ashore in chapter 7, the LE847U's color was decent, if still not up to the level of the other sets in the lineup. Swann's face, for example, held a slightly cooler, bluer cast than it should have, and there was slightly less richness and saturation to deeper colors like the blue sea.

In dark areas, the Sharp betrayed a bluish tinge to black areas and deep shadows that was exacerbated by its brighter black levels. Those areas looked more discolored than those of any TV in the room, although in lighter shadows the 65-inch Vizio's bluish tinge was worse.

Video processing: The LE847U performed basically the same as the LE640U in this category, which is to say not very well. Unlike last year's models such as the LC-830U series, 2012 Sharps are not capable of passing the correct 1080p/24 film cadence in my test. Instead, the deck of the Intrepid from "I Am Legend" showed either the choppy stutter of 2:3 pull-down or the too-smooth look of dejudder. The former occurred when I set Film Mode to either Off or Advanced (0), while any of the other Advanced values caused dejudder to kick in.

Despite the presence of 11 smoothness settings, the adjustable dejudder basically toggled between Off (at 0) and Really Smooth (+1 or higher). I'd like to have seen a greater range of visible effect, such as Samsung's system provides, or even a single setting that keeps some judder, like Sony's Standard setting.

The Sharp does offer the option to get full motion resolution without smoothing. To do so you have to engage either of the 240Hz modes. One, labeled AquoMotion 240, revealed all 1,200 lines, while the second, called simply "240Hz," came in around 1,000. There's also a pair of 120Hz modes that yield around 600 lines.

Uniformity: Although not terrible for an edge-lit LED, the backlight of the LE847U showed the second-worst clouding in our lineup, after the 60-inch Vizio. A slightly brighter area in the middle left and another on the bottom-right corner were visible in the darkest scenes and letterbox bars, respectively, although during most scenes they weren't bothersome.

From off-angle the TV performed reasonably, washing out and discoloring blue at about the same rate as the other 60-inch-plus sets, although it did dim more quickly than the 65-inch Vizio, and maintained black-level fidelity better than the 55-inch Vizio.

Bright lighting: Here's where the big Sharp excels. The LE847U has the same very matte screen finish as the LE640U, and performed just as well in a bright room, beating all of the others in this department. It muted reflections nicely, especially compared with the mirrorlike 65-inch Vizio, and did a good job maintaining black levels.

3D: The Sharp LE847U showed similar mediocre 3D quality to the LE745U I tested earlier. I expected it to perform a bit better since its panel has a faster refresh rate, but in fact it actually seemed a bit worse. I didn't have an LE745U on hand to compare it with directly, but pitted against the one comparison TV both had in common, the Panasonic ST50, crosstalk on the 847U appeared even worse.

I consider crosstalk, which appears as a double-image or ghostly outline in 3D objects, the most objectionable artifact of 3D, and it was rampant on the 847U. During "Hugo," my favorite 3D torture test, the face of Isabelle at 16:19 evinced an obvious black line along the right side, an effect of the double image. Numerous other instances occurred throughout the film. The Samsung, as well as the passive Vizios, looked significantly better in terms of crosstalk reduction.

I compared the LE847U to the same lineup that I used for 2D, although I swapped out the 3D-incapable sets and swapped in the Samsung UN55ES8000, my 3D reference. Compared with it the Sharp showed a dim 3D image in its default Movie setting, and shadow detail was a bit less visible, although color was relatively good. The LE847U was actually dimmer than even the plasma, although of course that can be fixed by tweaking the default picture settings in 3D.

Sharp didn't send us a pair of current 3D glasses for this review so I used the company's AN3DG20EL specs, the same ones that came with the Elite review sample (Sharp told us they're the same as the current AN3DG20B models). They're not as light as the Samsung or Panasonic specs -- not to mention the LGs -- but easier to wear than the bulky Sonys and much sturdier than the Samsungs.
