8K TV ?? like the huge Sony ZG9? are on the brink of extinction due to their high power consumption
E.Energy saving is very popular. If you use particularly energy-efficient devices instead of electricity guzzlers, you reduce CO2 emissions and your electricity bill. Years ago, the European Union introduced the so-called Energy label introduced. This is emblazoned in the shops on washing machines, dishwashers and refrigerators as well as on lightbulbs and TV sets. A scale from A to G shows how economical the products are with electricity. And when more and more economical devices came onto the market over the years in certain product groups such as refrigerators, the EU added a plus sign to the classes: A +, A ++ and so on.

What’s new with energy labels?
The power consumption of televisions is highly dependent on the picture settings. In the settings recommended by COMPUTER BILD for correct film playback, consumption is often below the standard specifications.
New energy label: what does that mean for televisions?
According to the data sheet, a noticeably large number of these devices currently consume around 110 watts. For good reason: This means that they are just in efficiency class A. However, one or the other manufacturer regulates the brightness of their TV images down. Example: The LG OLED 55C9 consumes 111 watts according to the data sheet, but the economy mode with poor image quality is set in the factory. In cinema mode, the quality is much better, the picture is brighter, but the consumption is around 30 percent higher ?? that then corresponds to class B. Translated into the new energy label, the device would have efficiency class G in both cases. To achieve the next better class F, consumption would have to drop by around 30 percent to 79 watts ?? with the same image quality, the current situation is unrealistic. Inexpensive LCD TVs and monitors could just do that. The Samsung 55NU7179, for example, has a standard consumption of 111 watts. The underlying standard picture mode is comparatively bright, the better quality film mode gets by with a little less power ?? the upper limit for F could be kept with a slightly changed factory setting.
Early Full HD plasmas were not a food contender with 400 watts and a screen diagonal of a good 100 centimeters, the Panasonic TX-42PZ80E (in the picture) swallowed 400 watts.
What do the manufacturers say?
Inexpensive LCD televisions have a screen diagonal of around 1 meter and are far below 100 watts (in the picture a Samsung GU43TU8079 with 69 watts), even the popular 55-inch models only need a little more than 100 watts.
Is there a limit?
The comparison of the upper consumption limits for old and new energy classifications shows: From 2021, most televisions will have a red instead of a green consumption label? although they are not power guzzlers. From 2023, TVs in consumption class G will have to disappear from the market.
What does that mean for HDR & 8K?
The new energy label for televisions is similar to the previous one, but also states the HDR power consumption ?? and sets much stricter limit values.
