Buying a monitor: how to save electricity - and money


Monitors can be real power eaters. With an efficient device, you not only do good for the environment, but also relieve your wallet. […]

Have you ever thought about power consumption when buying a monitor? It’s worth it: a conventional computer screen consumes more power than a notebook when operating at around 40 watts. So if you sit at the screen a lot, your electricity bill is noticeably burdened. That’s why we’ll show you what to look for when buying a monitor.

That’s why monitors are power guzzlers

Basically, the larger a monitor is, the more power it consumes. Therefore, when choosing a monitor, consider how you want to use it. Especially those who work in the office or home office with several programs at the same time appreciate a size in which they can arrange several documents and programs side by side. In most cases, a screen diagonal of 24 inches is sufficient for this at most. But in any case, it is better to connect one larger monitor to the computer instead of two smaller ones.

A switched–on monitor usually has a constantly strong backlight – regardless of whether this is necessary at all with the current ambient light and the displayed content. A lot of energy fizzles out here without any visible benefit.

A screen also consumes constant energy when the computer is turned off and the screen goes into power saving mode. This is usually between 3 and 10 watts – even on weekends and during the holidays.

Clever functions for saving electricity

All this does not have to be. There are monitors that have a low consumption by design and always adapt their performance to the current conditions. This can be done in several ways:

  • Depending on the image content, the backlight can be adjusted so that up to 30 percent energy is saved without reducing the image quality.

  • The brightness of the screen is automatically adjusted to the ambient light, saving even 60 percent of energy.

An energy-efficient screen should also have a mechanical power switch, so that no more electricity is consumed when switching off.

Our tip: EIZO FlexScan EV2485 Swiss Edition

EIZO has done its job in this area, for example with the EIZO FlexScan EV2485 Swiss Edition. Not only the low power consumption of just 12 watts per hour on average is striking. If the monitor is not used, it can be completely disconnected from the power with the power switch.

The monitor also adapts the backlight to the displayed content: the EcoView optimizer displays media content optimally without users noticing that the backlight is reduced.

A sensor also measures the ambient light. With Auto EcoView, the brightness is automatically adjusted depending on the ambient light, so that viewers have an optimal picture in front of them at any time of the day.

With all these measures, you save a lot of electricity – and therefore money. And this without compromising on other functions: the devices are ergonomically designed, have docking functions, precise color control and are uncompromisingly multimedia-capable.

Sustainability as a core task

The extent to which EIZO is committed to the sustainability of its products is also demonstrated by the recently obtained certification according to the Swedish TCO standard of the ninth generation. The criteria have been tightened so much compared to the previous generation that EIZO is one of the first companies to meet the standard. These include the following innovations:

  • Use of safe flame retardants and plasticizers
  • Use of safe detergents
  • Disclosure of the environmental impact of the entire product cycle
  • Evaluation of the ease of repair
  • Management systems for work, health, safety, environment and ethics along the entire supply chain
  • Energy management system according to ISO 50001

In concrete terms, this means for the EIZO monitors that they are made of environmentally friendly materials of high quality. The service life is extended and the devices can be repaired if necessary. You can find more information here.

Sustainability pays off

Anyone who relies on a sustainable monitor from EIZO therefore benefits twice: thanks to a long service life, you save on the acquisition costs over the years and thanks to low energy consumption, the energy costs also drop noticeably.

Roland Kudelic, System Engineer and responsible for hardware and software procurement at the Basel-Stadt Compensation Fund, confirms that the purchase of energy-efficient monitors is also worthwhile for companies: “Compared to competing products, we also save a lot of electricity and thus energy with EIZO monitors. This also pays off on the cost side and we make an active contribution against climate change.»
