Optimising television settings could save as much as £100 a year for UK consumers, according to website HDTVTest.
According to the website, which specialises in reviewing HD televisions, TV manufacturers artificially boost the brightness and contrast of their TV’s to help them compete in brightly lit shops. But this level is unnecessarily high for the home environment, and compromises picture quality.
The experts said that an average family could save enough money for a half year’s satellite subscription by turning down the brightness and contrast on their TV, and as a nation the UK could be wasting billions of pounds in electricity by not turning the levels down.
As part of their testing process, the specialists at the website adjusted the settings on televisions through a procedure known as calibration to obtain the best picture quality possible. In the vast majority of cases they found that a television’s power consumption reduced significantly after calibration.
Vincent Teoh, editor of HDTVTest, said: “Calibrating your TV is similar to washing at 30o or only putting the right amount of water in the kettle – it’s more environmentally friendly and more cost effective. The benefit with calibrating a TV is that the picture quality is actually improved.
“When we calibrate a television we adjust the picture to be as close to real life as possible, in fact we achieve a quality akin to what directors and film producers see on their professional studio monitors.”
The website said there were some televisions on the market today that, if calibrated properly, could reduce its running costs by 40 per cent.
“Of course, the most important thing you can do to reduce the running cost of your TV is to turn it off at the mains rather than just leave it on standby.
“However, just like tuning a car engine can make it run better and more cost effectively, so can calibrating a TV,” Teoh said.
