Samsung Denies Cheating on TV Energy Efficiency Tests

An independent research group accused Samsung of gaming European TV energy efficiency tests.

First it was Volkswagen, and now Samsung is being accused of cheating tests, in this case for energy efficiency on their TV’s.  An EU-funded research group says Samsung is gaming European TV energy efficiency tests—a claim the manufacturer strongly denies.   ComplianTV told The Guardian that it recorded consistently higher energy consumption rates in real-world situations than in official test conditions.  Samsung TVs have a feature known as “motion lighting,” which reduces screen brightness when the picture on the screen is in motion. According to ComplianTV, the Samsung TVs reduced their brightness, and therefore power consumption, during international electrotechnical commission (IEC) testing, but not in real-world situations.   ComplianTV’s research has not yet been published, so all the details are not known. But The Guardian said the European Commission has fielded similar complaints about TV testing from other EU states. The Swedish Energy Agency, for example, said it has seen TVs that recognize the standard footage that it uses for its TV testing and adjust accordingly. “These displays immediately lower their energy use by adjusting the brightness of the display when the standard film is being run,” the agency said in a letter seen by The Guardian. It did not, however, specify which manufacturers made these TVs.  Still, the European Commission told The Guardian that it will investigate the allegations and tighten regulations in an effort to prevent the use of “defeat devices” in consumer products.   This is not the first time Samsung TVs have prompted controversy. In February, Samsung’s smart TV privacy policy warned users that spoken words containing personal or other sensitive information “will be among the data captured and transmitted to a third party.” The company later clarified the voice-recognition capabilities of its smart TVs and said its sets do not monitor living room conversations.
