Interesting idea, wrong assumptions Rated 1 out of 5 stars
Black screens can only reduce energy usage on CRT monitors (I've seen numbers of 5-20%), but crucially NOT on TFT monitors. In fact, they may actually INCREASE energy usage on TFTs. Given that most monitors out there are TFTs, this addon seems to defeat its own mission.This review is for a previous version of the add-on (1.3).
