A research study by THX claims that as well as improving your TV's picture quality, calibrating it properly could reduce energy consumption by as much as 50 per cent.

The THX study evaluated plasma and LCD HDTV performance, and found that a properly calibrated viewing mode consumed less energy than the TV manufacturer's Vivid and Dynamic modes.

An easy way to save
Savings for users ranged from 15 to 50 per cent, which could amount to £30 a year, depending on your electricity tariff. The annual consumption and cost calculations are based on an average four hours of use per day.

THX engineers evaluated more than 15 plasma and LCD models in the US. Plasma HDTVs manufactured before 2008 achieved the highest level of energy savings after professional calibration.

"Newer HDTV models are using less energy than ever as a result of advances in panel manufacturing," says John Dahl, director of education at THX. "But both newer and older plasma and LCD HDTVs can experience additional energy savings as a result of proper video calibration."
