Sharp LC-LE640U review: Sharp LC-LE640U
Sharp LC-LE640U
If you ask Sharp (or me), one of the best reasons to buy a new HDTV, especially if you have one already, is to go big. After introducing massive 70- and 80-inch LCDs last year at prices that in context actually deserve the word "affordable," the company will double down on screen size in 2012. Its entry-level LC-LE640U series occupies the value sweet spot in the company's lineup: the 60-inch version reviewed here costs $1,500 at introduction, while the 70-incher is $2,500. That's a lot of screen for the money, and those prices will inevitably fall further later in the year.
The Good
The Bad
The Bottom Line
Our tests didn't reveal world-beating picture quality, but the 640U does offer accurate color and a matte screen--the latter is especially important in rooms where ambient light control is an issue. Its weaknesses, namely lighter black levels and less-than-perfect uniformity, leave the door wide open for competing plasmas to score higher, but I have a feeling that Sharp's ultra-aggressive pricing, and the mass-market appeal of LED/LCD, will guarantee the 640U its own sweet spot among the most popular big-screen TVs of 2012.
Editors' Note June 12, 2012: The rating on this review has been modified from 7.1 to 7.4, and its Performance sub-rating changed from 6 to 7, to reflect recent reviews since the time of publication.
Series information: I performed a hands-on evaluation of the 60-inch Sharp LC-LE640U, but this review also applies to the other screen sizes in the series. All sizes have identical specs and according to the manufacturer should provide very similar picture quality.

Design
The basic-looking 640U series doesn't try as hard as many of its competitors to make a splash in the living room. I appreciate the narrow frame around the image--which does thicken up a bit along the bottom. Its burnished texture is a nice departure from glossy black, although the bottom section is half-glossy, as is the top of the nonswiveling stand, which tends to collect dust. The illuminated ^ icon bottom-center can be turned off.
Thinner and longer than most clickers, Sharp's wand is plagued by lack of backlight and insufficient differentiation between the mostly too-small keys. One great feature, however, is the trio of programmable buttons that provide instant access to your favorite apps. Another, new for 2012, is the big red Netflix button.
Sharp didn't change much about the menu system from last year, and it's serviceable if unremarkable. Navigating among the choices along the main top strip could be snappier, and I prefer overlays to Sharp's method of reducing the picture size to make room for its menus.

Features
Sharp reserves its higher refresh rates, 3D compatibility, and step-up Smart TV functions, as well as the extra yellow pixel that is Quattron, for the 640's more expensive brethren. Its edge-lit display (and those of step-up Sharps) lacks the local dimming found on some competitors. Note that unlike last year, the 70-inch Sharps for 2012 are also edge-lit, not full-array. That said the 640U is well-equipped for the price, with highlights including full USB and DLNA Media access and built-in Wi-Fi.
A couple of other extras are unique to Sharp. IP control is designed to interface with custom installation remote control systems, such as Control 4, AMX and Crestron, that can operate over Ethernet as opposed to RS-232. Aquos Advantage Live is Sharp's excellent live help feature, which I described in 2009. I appreciated the full onscreen manual--a carbon copy of the PDF version, complete with table of contents.
Smart TV: Sharp's streaming video selection includes Netflix, YouTube, Vudu and CinemaNow. There's no streaming audio offered, however. Miscellaneous apps come courtesy of Vudu Apps, where Twitter, Facebook, Picasa and Flickr are the standouts.
If you're comparing by content Sharp falls short of most major-name competitors, missing Hulu Plus, Amazon Instant and even Pandora and Napster (the latter two were available on 2011 Sharps). Its interface is simple enough, consisting of a launcher strip across the bottom of the screen. Higher-end models like the LC-LE745U series get a "full-screen" interface option with a couple more apps (Hulu Plus and Skype) and a web browser.
Picture settings: Five tweakable picture modes, a gamma slider, a full color management system and a two-point grayscale control place the 640U squarely in the middle of the pack for adjustability. New for 2012 is the ability to tweak the strength of dejudder from really smooth to even smoother.
Connectivity: I have no complaints on this front. Four HDMI 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, rounds out the package.
Picture quality
The LC-LE640U performs better than what I remember of last year's 830U, thanks primarily to somewhat better uniformity and perhaps deeper black levels. It won't blow videophiles away, however: blacks are still grayish compared to better LEDs and plasmas, while uniformity and off-angle were still issues. I appreciated its color accuracy and matte screen, but unfortunately video processing took a step backward.

Black level: The Sharp performed worse in this department than most of the others in the lineup when I checked out "Harry Potter and the Deathly Hallows: Part 1." In dark scenes its blacks were generally as deep as those of the Samsung and a bit brighter than the LG and the Vizio. Mixed scenes, like the face of Snape as he strides across the grounds (4:10), looked punchier if a bit less accurate on the Vizio and about the same as on the LG and Samsung. As expected the Sony and Elite trounced the others, including the Sharp, in this category.
Details in shadows, like the dark clothing of the evildoers in Chapter 1, looked good, with more realism than on the Samsung if a bit less of a natural look than on the Elite or the Sony.
Speaking of unnatural, I was annoyed when the Sharp's backlight turned off completely and then abruptly fired up again at the 9:50 and 10:01 marks after fades to black. I prefer the smoother fades of most of the other sets, whose backlights remained on or undimmed gradually enough not to notice.
Color accuracy: Overall the 640U fared well at rendering skin tones and other colors, approaching the color palette of the very accurate LG and Vizio and appearing a bit more accurate than most of the others in the gathering in Chapter 3, for example.
On the 830U last year I complained about the overly blue-tinged blacks, but on the 640U they weren't as obvious. Shadows and black areas appeared less blue and more inaccurate on the Sony and Samsung displays, although the rest of the lineup outdid the Sharp in this area.
Video processing: Unlike last year's models such as the LC-830U series, the 2012 640U was not capable of passing the correct 1080p/24 film cadence in our 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). We'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.
One video processing bright spot was the Sharp's ability to preserve its full-motion resolution--about 600 lines in this case, typical for a 120Hz TV--without introducing dejudder.
Uniformity: My biggest complaint against the 830U last year centered on its poor screen uniformity, and while Sharp improved that issue on the 640U sample I tested, it was still the worst in our lineup. A slightly brighter blotch in the left-center of the screen was visible in test patterns, and while it wasn't obvious in most material, I noticed it occasionally during camera movement, for example the pan over the bad guys in Chapter 2. Test patterns also revealed a few other blotchy spots in our review sample, but none were as visible or annoying during program material.
From off-angle the Sharp lost black level and color fidelity (becoming bluer-tinged) at about the same rate as the Samsung, and kept black level (but not color) marginally better than the LG and Vizios. Both the Sony and the Elite were better from off-angle than the Sharp.
Bright lighting: The Sharp's matte screen was very good at rejecting reflections from ambient light, doing about as well as the other matte LCDs (the LG, the Vizio and the Samsung) in our bright room. It didn't preserve black levels as well as the glossy Sony or Elite screens, however, and even fell a bit short of the other matte screens in this regard.
