Chart key
Model: The HDTV model name and manufacturer. Default sort is by technology type, with newest reviews listed higher on the chart.
HDTV type: Flat-panel LCD, plasma, or rear-projection (RPTV). CRT models were excluded from this comparison because we no longer test them.
Screen size: In inches diagonal. All TVs on this list are wide-screen models with a 16:9 aspect ratio.
Default setting (watts): Measured using the default settings when the TV's picture is on. Prior to the Energy Star 3.0 update in November 2008, the default settings were a sort of "torch mode," with high light output and correspondingly high power consumption. But since the update many new models have dimmer pictures and less power use in the default mode. See The Basics of TV power for more.
Default setting (watts per square inch): The "Default setting (watts)" result divided by the screen size of the TV in square inches.
Default setting (cost per year): Using the default picture setting on a TV, this is the amount of money the TV would cost to operate 365 days, assuming it's turned on for 5.2 hours a day and off for 18.8 hours. We currently use the average price of energy in the U.S. during 2008, which is a little more than 11.35 cents per kilowatt hour, according to the Energy Information Administration (the most recent full-year figure; the linked chart at eia.doe.gov actually indicates 11.36 cents). All of the TVs on this list, whether reviewed in 2008 or 2009, use these figures in calculating this amount. However, the true cost of operating a TV can vary widely depending on local electricity costs and hours used per day.
Calibrated setting (watts): Measured using the calibrated picture setting when the TV's picture is on. CNET calibrates all HDTVs it reviews, which includes adjusting luminance (light output) to a certain level. Since power use varies with luminance, this wattage number provides a better, direct comparison than default setting, where luminance is not equalized.
Calibrated setting (watts per square inch): The "Calibrated setting (watts)" result is divided by the screen size of the TV in square inches.
Calibrated setting (cost per year): Using the same figures as for "Default setting (cost per year)," this is the amount the TV costs to operate per year in the calibrated picture mode.
Notes: This chart contains 92 TVs tested by CNET for power consumption between January 3, 2008, and November 9, 2009. For additional details on our testing methodology, read our How we test TV power consumption Web page. More data, including consumption in power saver modes and "Good, Fair, and Poor" ratings is available in the Juice box at the bottom of every CNET HDTV review published since June 22, 2007.
