As part of our article Eco TVs – how green is your TV?, where we looked at the ways the various plasma and LCD TV makers are approaching the challenges of bulding in power efficiency while at the same time keeping the stunning high definition images we’re expecting in our panels, we looked a 5 current models.
LG 42LH50YD LCD TV
The LG 42LH50YD LCD TV allows you to choose between five different energy saving modes, or you can leave it switched off. The picture quality was very good (once tweaked with the Dynamic Contrast setting).
Sony’s Bravia KDL-40WE5 LCD TV combines a number of power saving features with a whole bunch of high-end facilities. The TV offers full high definition resolution, has four HDMI digital inputs, and both HD digital and analog TV tuners.
All these TVs – including the LG, which is not specifically marketed as an eco TV – loped comfortably over the MEPs line, at least according to my meter.
I calculated 3.5 stars for the LG, which puts the Panasonic in last place when it comes to energy efficiency, and the sheer size of its screen ensures that it comes in last place for overall energy usage as well.
But were it not for the less than full-HD resolution, I’d forgive all that for the plasma picture.
At the other end of the scale, the clear winner on everything to do with money, and with power consumption, is the Toshiba. At just over 90 watts on my meter, it will only cost you about $50 a year to run, and, on top of that, is the cheapest to buy.
