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.

Default view of Sharp AQUOS LC-70LE640U
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.

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.
AQUOS by c|net (Mar, 2012)
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.

Performance Real world tests of Sharp AQUOS LC-70LE640U

black levels

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.
AQUOS by c|net (Mar, 2012)
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.

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.

Sharp's built-in help is the best in the business.

Reviews Word on the street

Read the review (Mar, 2012)
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.

Picture quality

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).

Sharp didn't change much about the menu system from last year, and it's serviceable if unremarkable.

A couple of other extras are unique to Sharp.

Panel

The 640U is understated and compact for a large-screen TV.
Sharp AQUOS LC-70LE640U 70" | Rated 74% by by c|net (Mar, 2012)
Its interface is simple enough, consisting of a launcher strip across the bottom of the screen.
Sharp AQUOS LC-70LE640U 70" | Rated 74% by by c|net (Mar, 2012)
I prefer the smoother fades of most of the other sets, whose backlights remained on or undimmed gradually enough not to notice.

Sharpness

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.
Sharp AQUOS LC-70LE640U 70" | Rated 74% by by c|net (Mar, 2012)
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.
Sharp AQUOS LC-70LE640U 70" | Rated 74% by by c|net (Mar, 2012)
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.

Apps

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.

Miscellaneous apps come courtesy of Vudu Apps, where Twitter, Facebook, Picasa and Flickr are the standouts.

A red button and favorite apps keys differentiate an otherwise subpar clicker.

I appreciated the full onscreen manual-a carbon copy of the PDF version, complete with table of contents.
