LG 55LM6700

  • Good color performance
  • Better 3D performance than most TVs
  • Striking styling
  • Blacks disappoint most
  • Uniformity can be an issue
  • Refresh-rate specification is misleading

Experts say that the LM6700 is a solid, though not class-leading, LED TV with lots of useful and well-executed features. Before taking the plunge, however, there are some caveats to consider. Two screen sizes are available: the 55-inch 55LM6700 (*Est. $1,500) and the 47-inch 47LM6700 (*Est. $980).


Things aren't quite picture-perfect, but many will really like what they see. Lots of reviewers have been disappointed by the black levels in LG's 2012 LED TVs, and that's in evidence here. While some reviewers say blacks are fine, most say that they are merely average -- and a step back from what even LG offered last year. Screen uniformity is another problem. As with all edge-lit LED designs, some edge and corner brightness can be seen, though some reviewers say that it isn't too bad -- indicating that the issue can vary greatly between individual sets. Colors, on the other hand, are first-rate, especially if you take the trouble to adjust them. This TV is advertised as having a 120 Hz refresh rate. It technically doesn't, and that's shown up in testing as poorer control over motion blurring than other 120 Hz sets. More on that right below as we discuss features.


The claim of a 120 Hz refresh rate is misleading. In the race to bigger and better specs, many makers -- including LG -- have taken to quoting a set's apparent refresh rate (in LG's case, that's called TruMotion), which is derived from the screen's actual refresh rate plus the scanning rate of its backlight. When a set's native refresh rate is 120 Hz, that really doesn't affect much in most viewers' eyes since the jump from 120 Hz to 240 Hz is rarely visible in most program material, experts say.

But things are dicier in the case of the LG LM6700, as it uses a standard 60 Hz refresh panel but is offered as a 120 Hz set based on its TruMotion technology. However, several reviewers note that despite the technology, motion blur is more pronounced than on other 120 Hz TVs, and more typical of 60 Hz sets.'s Gary Merson is perhaps the most vociferous about this marketing practice: "We find these claims incorrect and unsupportable," he says.

That aside, however, there's lots to like about the LM6700s feature lineup. Refresh rate aside, it's identical to what's found in the company's step-up LM7600 series, and not far removed from what's seen in the flagship LM9600. You get passive 3D that most say works very, very well -- and is preferred by many (though perhaps not videophiles) for its simple approach to casual 3D viewing. You also get six pairs of glasses in the box; extras are inexpensive (around $10 each).

The built-in Internet streaming works well, and access is aided by the standard Magic Motion remote that brings Wii-like control to the act of scrolling through TV menus. Not everyone is a fan of the remote, and it might take a little time to get the hang of it, but it's mostly considered a positive. In terms of content, sets from other makers offer more, but there's enough here to cover just about all the major content types and all of the top-tier content providers -- with a few notable omissions such as Amazon Instant and Pandora. The TV is DLNA-compliant for streaming your own movies, music and photos from a computer on the same network, and Wi-Fi is built in. There's also a web browser that works better than most found in other TVs (though that's setting a pretty low bar), and an app store that few find to be very worthwhile.


The LM6700 is one of the more striking TVs in its price range. When it comes to design, most have nothing but praise for the looks of the LG LM6700. It actually shares the same design as the step-up LM7600, including a barely-there bezel around three sides and very thin form factor that makes the TV as attractive off as it is on. The swiveling base is also more highly styled than the traditional pedestal. Connectivity is ample and includes four HDMI inputs.


For the extra scratch, a step up might be in order. We saw different opinions regarding the value of the LM6700. At current street prices, however, the price premium compared to the LM7600 is small enough that the step-up set is most likely a better buy.

Bottom line

The LM6700 is the exact same set as the step-up LM7600, except for the latter's enhanced refresh rate. Unless you are squeezed right against your budget, that makes the LM7600 almost a no-brainer for its better motion performance -- albeit in limited situations (like watching fast-moving sports). Otherwise, like the LM7600, the LM6700 enjoys solid though not spectacular picture quality and a well-executed set of features with a few unique twists -- such as the innovative though quirky motion controller.

Excellent Though based in Europe, includes coverage of U.S. models in reports that are technically competent, comprehensive and useful to both videophiles and more casual buyers. Black levels fall short of the best LED TVs, but picture quality is said to otherwise excel. Some criticism is leveled at the Smart TV platform, but the set's design is beautiful and the 3D performance is "hassle-free and pleasant." The set earns a Highly Recommended award.

Excellent The 55-inch LG 55LM6700 earns a relatively harsh assessment from CNET. David Katzmaier is disappointed in many factors of the set's picture quality, most notably black-level performance. Testing is comprehensive and hands-on.

3. Sound & Vision Magazine

Excellent This long and detailed report on the 55-inch LG 55LM6700 has something for everyone, from dyed-in-the-wool TV geeks to TV buyers wanting a relatively jargon-free assessment of a set's positives and negatives and whether or not it is worth considering. "On the whole, I like LG's 55LM7600 a lot," writes Geoffrey Morrison. However, he qualifies his assessment by saying that picture quality is only "decent," and adding that "I expected more for $2,100."

Excellent While finds the same issues with black levels as CNET, this thorough reviewer still finds enough positive about the 47-inch LG 47LM6700 to call it a "spectacular" TV. Those positives include great color, a strong Smart TV platform, the innovative Magic Motion remote and "the best 3D images on the market."

Excellent While videophiles won't find the details they seek here, does a good job of evaluating the 47-inch LG 47LM7600 for the rest of us. Discussion is briefer than that of most other expert reviewers, though greatly expanded from what was typically offered in years past. Regardless, you'll need to be a subscriber to read this article and to see how this LG set fared on its own and relative to its competition.

Excellent doesn't devote as much discussion to the LM6700 (in this case the 55-inch LM6700) as the sources above, but bases its take on hands-on testing. Will Greenwald is impressed enough to give the set a 4-star (Excellent) rating. Picture quality is called good despite blacks that don't quite measure up to other sets', including last year's LG models. The passive 3D and the set's motion-based controller, which are well liked elsewhere, come in for more criticism here.

Very Good Reviews here are competent and hands-on, but not quite as smoothly executed or detailed as those at sources we rate higher. An accompanying video review helps, but only a little. Positive, negative and neutral considerations are listed for the 55-inch LG 55LM7600. The set seems well liked, but the overall score posted with the review differs by nearly a half point from what's posted on the site's review comparison table, lending some confusion to matters.

Excellent Gary Merson conducts a fairly technical, hands-on review of the 55-inch LG 55LM6700. He finds lots to like about the set, including its relative value, but he takes LG to the woodshed when it comes to how it's chosen to market the TV as having an enhanced refresh rate (120 Hz). Merson is also one of the few reviewers to test the TV following a firmware update that added a dejudder processing (to smooth motion in film); most other reviews simply say that option is missing.

9. CNET (Australia)

Very Good The U.S. edition of CNET has yet to weigh in on sets in the LM7600 series, but the Australian version does offer its take on the 55-inch LG 55LM7600 and grants it an Editors' Choice award. The reviews here, however, while based on hands-on evaluations, are far less detailed than those on CNET's U.S. site.

Excellent includes the 55-inch LG 55LM6700 in its current batch of HDTV reviews. Testing is competent and hands-on, though not as detailed as that of some other reviewers. Discussion is balanced and greatly expanded from past years, though still briefer than that of many reviewers. Conclusions are only available to subscribers, however.

Very Good More than 150 owners have weighed in on the 55-inch and 47-inch versions of LG's LM7600 LCD TV (reviews for both screen sizes are grouped together). The overwhelming majority seems very happy, as evidenced by the 4.3-star overall rating. We did see a few negative comments regarding screen uniformity, however.

12. PC World

Very Good PC World reviews fewer TVs than some other experts, though its reports are testing based. The 55-inch LG 55LM6700 doesn't fare well here. Picture quality is a letdown and the motion control "can often be frustrating," says Lincoln Spector.

Good has far fewer reviews of the 55-in LG 55LM7600 than (just over 30), but an even higher level of satisfaction. All but two owners at the time of this update said that they would recommend the TV to a friend. User ratings of the 47-inch 47LM7600 are also available here, but it receives fewer reviews and a slightly lower (but still pretty good) rating.

Very Good This is another hands-on test of the 55-inch LG 55LM6700. It earns a high rating and an Editors' Choice award. Caleb Denison notes that screen uniformity is pretty good -- reflecting the fact that this performance factor can vary greatly from specific set to specific set. He also has fewer complaints about black levels than most. However, he finds some usability issues with the remote.
