El Reg reports

The NRDC [Natural Resources Defense Council] reckons TV makers are configuring sets to perform well on government tests, while in the living room they become energy hogs.

Its specific claims are:

  • The TVs perform well on the US Department of Energy-mandated energy use test--but that's based on a clip that doesn't match real-world video content. ([To El Reg,] that seems like a slip-up by the DoE);
  • TVs from Samsung, LG, and Vizio are designed to disable energy-saving features if the user changes their screen settings, but there's little or no warning about this. This, the NRDC says, can as much as double the power consumption; and
  • UHD TVs turn into energy hogs when they're playing high dynamic range (HDR) content, but HDR isn't included in the DoE's test (again, surely that means the DoE needs to update its tests?).

The NRDC says European testing seemed to match another observation it made: that during the DOE test loop, some TVs seemed to exhibit "inexplicable and sustained drops in energy use". It suggests that software is specifically detecting the test loop and adjusting the TV's performance to suit.

One assumes that "a clip" refers to the standard video loop used in the tests.

    What is with SOs? Mine is perfectly willing to throw money away on a Netflix subscription, and rent from RedBox and buy from Amazon. And she still whines that I won't also pay for cable TV for her. She thinks the police are going to drag me off to prison someday for piracy.

    Her concern for the environment is highly selective. She'll sit in her parked car for 15+ minutes at a time, running the engine so she can enjoy A/C, instead of getting indoors somewhere. Even when it's cooler, she still wants the A/C so her allergies aren't aggravated by all the pollen floating around the great outdoors. Her fuel economy numbers are of course horrible.

    > What is with SOs?

    Have you tried asking her, and then listening, rather than informing her that she's being dumb? Maybe, just maybe there is something you are missing.

    Nah. Women are stupid.
