Last year Sharp made a splash with ads featuring Star Trek's Mr. Sulu--George Takei--comically extolling the virtues of a technology called Quattron. With the memorable "Oh, myyy" tagline, the spots attempted to convince TV buyers that the technology, which adds a fourth yellow subpixel to the standard array of red, green, and blue, improved color fidelity. Despite covering the launch in-depth, we never reviewed one of those 2010 TVs, but after spending some time with the 2011 version, represented by the LC-LE830U series, we're a bit less impressed than Sulu was.
If you calibrate the LC-LE830U series properly--something we do with every TV we review--the yellow pixel has no major impact, positive or negative, on picture quality. What will have a negative impact for critical viewers are the set's lighter black levels and subpar screen uniformity. We appreciate some aspects of its performance, as well as a feature set with Wi-Fi and best-in-class product support, but in the end the LC-LE830U does little to stand above the tough competition in the edge-lit LED-based LCD TV category.
