Your shiny new Free energy Star-rated TV is lying to you. At least, that’s the gist of a new study on Goggle box energy usage by the National Resources Defense Quango (NRDC), which was released to the public Wednesday.
The study — which comprises a battery of tests the NRDC and its consultant bureau Ecos Enquiry conducted on a batch of 2015-2016 Samsung, LG, and Vizio televisions — claims that the exploitation of loopholes in the Department of Free energy’s (DOE) Energy Star rating system could exist costing viewers more than than $ane.2 billion in extra energy costs over the lifetime of their new Television set. What’southward more, the new study concludes that more than than 5 million metric tons of extra carbon emissions will be released into the atmosphere due to the new TVs’ unexpected ability requirements.
In that location are multiple means your new TV’s energy use can double, claims the NRDC, many of which can take effect without your knowledge. In other words, your “energy efficient” Television set may not be efficient at all, potentially affecting your budget and the environment alike. How is this possible?
Cheating the examination
Let’s begin with the DOE’s method of testing, which uses a 10-minute loop that the NRDC claims is far from reflective of the way consumers really sentinel Television set at abode.
“The ten-minute video loop used in the test method for measuring and reporting average Tv ability
contains a collection of unusually brusque scenes that is not representative of about existent-world content,” the report claims. That would appear to put the blame on the DOE. However, the report goes further, challenge that it’s possible sure TVs include software that detects when the TV is existence tested and games the system.
Information technology’s possible certain TVs include software that detects when the TV is beingness tested and games the organisation.
“We observed inexplicable dramatic and sustained drops in energy utilisation in TVs from certain manufacturers, beginning within the get-go minute of the video examination loop used in the DOE examination method for new TV models,” states the report.
To verify the anomaly, the agency created its own test loop designed to better reverberate real-globe viewing, with some very telling results. Power dropped by a whopping 58 percent on one of the LG TVs tested during the DOE’south 10-infinitesimal loop, yet it dropped by simply xiii pct with the NRDC’s “existent-world” testing loop. The test results were reportedly similar with Samsung TVs.
According to the report, that’s because the vast majority of Samsung and LG TVs utilize an energy saving feature called motion-detection dimming (MDD), which is designed to dim, or briefly turn off the Tv’s backlight organization when “rapid motility and frequent scene changes” occur. The tech is ostensibly designed to save energy during commercials and music videos, according to the NRDC, simply it besides works
well during the DOE free energy efficiency test.
“It is possible that some manufacturers have designed their TVs to detect the continuous occurrence of brusque scenes and frequent scene cuts and to ‘optimize’ their functioning to reduce ability when content with these characteristics is displayed,” the study claims. While not most as dramatic every bit the recent machine scandals by diesel makers similar Volkswagen (aka Dieselgate), it’s another reminder of the integral role regulatory oversight plays in consumer protection.
Modify the picture show, change the world
While Vizio TVs don’t employ the same motion-detection claimed to game efficiency testing standards, the report suggests there are other methods TVs use that make them much less efficient than their Energy Star stickers betoken. Vizio, Samsung, and LG TVs all employ software which disables “key energy-saving features,” on TVs substantially whenever yous modify your TV’s default picture way — in near whatever way. According to the study, changing the chief moving picture setting can “double” a TV’southward energy employ, often without your knowledge.
For instance, just switching to the Standard motion picture fashion on newer LG TVs (as opposed to the default Machine Power Saving feature) disables motility-detection dimming, likewise equally other energy saving features like automatic brightness control. Similar features are disengaged on Vizio and Samsung TVs, the latter of which tin undo energy-saving tech features by but changing the brightness or contrast settings by a single bespeak. The report claims that if just 1 third of users change their picture setting, the consequence could be billions of dollars in actress energy costs.

Of class, as reviewers, these features are frequently contrary to achieving the all-time performance from the TVs nosotros test. In fact, one of the first things nosotros do to optimize operation is turn off energy-saving tech. Yet, given that the features are essentially necessary for many new TVs to attain an Free energy Star rating, the NRDC wants manufacturers to be more than forthcoming.
“The manufacturers nosotros’ve spoken with have agreed, to varying degrees, to update the software on their new TVs and then the energy-saving features are more likely to remain enabled over the TV’due south lifetime,” the report states. “Thus far, LG has been the most responsive to our concerns,” the report adds.
HDR: High Drain Resolution?
Finally, the study reveals that the resolution of 4K Ultra High Definition TVs, likewise equally the new HDR (high dynamic range) format, are completely unaccounted for in the DOE’s standard exam, which taps out at Hard disk drive resolution.
It’s no surprise that the super-brilliant output required in key areas for HDR scenes bumps up the energy level, but the new examination is the first to employ HDR content equally part of the process. In fact, the report claims that viewing HDR content may increase a Tv’s energy employ by 30-50 pct.
“The manufacturers nosotros’ve spoken with have agreed, to varying degrees, to update the software on their new TVs”
Equally a specific case, the NRDC establish that a Samsung model 9000 TV with an almanac energy use rated at 142 kilowatt hours (kWh) of usage per year shot up to 329 kWh when free energy-saving features are disabled, while free energy usage jumped up to 389 kWh average per year when HDR content was introduced.
In addition, the report states that “Manufacturers have indicated the free energy-saving features on their televisions are automatically disabled whenever UHD + HDR content is played, and our testing confirms this.”
“This is quite significant,” the report continues, “every bit the power levels reported per the DOE examination method—based on default Goggle box settings and measured while playing HD content (the nearly common video format in 2016)—are half the values observed when playing UHD + HDR content, and in some cases even less.”
As you lot’d expect, the NRDC recommends a multi-point approach to fix the array of problems the report plant with current Energy Star standards. The organization wants TV makers to end deploying software that automatically disables energy-saving features without consumer noesis. In addition, the organization wants the DOE to design a new exam that accounts for real-earth watching and new TVs with UHD and HDR features.
Finally, the group wants manufacturers to piece of work on new technology that will make the new era of 4K UHD Boob tube more than efficient, including the use of quantum dots (a technology that Samsung has invested in heavily), as well as other efficiency technologies.
We reached out to each of the manufacturers for their side of the story when information technology comes to the NRDC’s findings.
For Samsung’south function, representatives had this to say:
Samsung firmly rejects the allegation that nosotros are misleading consumers. Our ENERGY STAR rating is based on the default setting of our TVs. The majority of users stay inside the default viewing settings through the lifetime of their television receiver. Furthermore, we strongly believe that consumers should always have the choice to customize the viewing experience on their Television.
LG’s response was similar, though more than detailed:
Simply put, LG disputes the findings in the report. LG has followed both the alphabetic character and spirit of the DOE exam procedure for TV energy testing, and we take great exception to the assertion that LG is “exploiting a loophole” in the government test procedure.
LG has had a mostly cordial and respectful relationship with the NRDC. We met with them and listened to their concerns. We raised our concerns about their methodology. We respectfully disagree with their conclusions, at least every bit far as LG is concerned.
For example, in that location is no consensus on how to define “normal viewing.” The NRDC’south “normal viewing” examination clip and LG’s “normal viewing” test clip show significantly different results. We wait forward to working with the DOE and stakeholders to develop a new examination clip going forward. For at present, the IEC test clip is the standard that the industry must follow according to applicable law.
Even before nosotros met with NRDC this summer, LG was working proactively with the EPA on related issues. The NRDC written report fails to point out how LG is addressing free energy saving features, both for current and future products.
LG is implementing software for consumer notifications on 2016 and ‘fifteen models that inform consumers that changing picture modes may impact energy consumption. It also allows consumers to turn on energy saving features in various movie modes.
LG’south 2017 Boob tube models also will include a number of enhancements to the automatic effulgence command (ABC) and motion eye care (MEC) features. Specifically, the ABC feature volition be implemented as the default in all picture modes (except HDR modes). What’s more, consumers will be able to activate MEC in all flick modes.
LG went on to say that information technology shares the goal of creating more than free energy-efficient TVs, and that the company is “confident” that its products are being tested with efficiency standards for “real earth use.”
We have withal to hear back from Vizio, just we volition update this study equally soon as we practice.
Regardless, information technology seems all of us need to look a lot closer at that Energy Star tag on appliances of all kinds. When electronics don’t perform as advertised, it’s not only affecting our wallets, it’s affecting the entire world around united states of america.
