The Eco TV earns its name by not sucking up juice when juice isn't needed, thanks to an onboard light sensor that monitors ambient lighting and adjusts the LCD's backlight accordingly: The darker the room, the less power the backlight draws. The 42-in. screen, which handles full HD (1080p) and cleverly hides its speakers in the back, is constructed from lead-free, flame-retardant components. Its packaging and manuals are all made of recycled materials. There has never been a more eco-friendly way to watch Dancing With the Stars.
