I had this in my TV 10 years ago.

It had a sensor and it adjusted the brightness according to lighting. Eco is IN again.

putting a product out there that actually works first. I've had 2 LG 50" plasma TVs become "unrepairable" in the last 2 years, the second within 6 months of coming out of the box.

Thankfully my new replacement didn't have to be a LG so I've got a nice shiny Samsung lCD instead....and you know what - it works!

So the TV in a dark room uses 69.5 percent less than standard models with the brightness cranked to 100%. 

How much would it save if the "Standard Model" is adjusted correctly for the same light level? 

I just love the "independent tests" where they pay for the answer they want to see.
