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.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.
