LCD-TFT and old CRT monitors

LCD monitors aren't like CRT ones. The first type of monitor consumes only 20-30 W, and lesser if it is a LCD-LED one. CRT monitors consume 80-100 W. It is clear that the black background in CRT monitors is a good idea to consume less energy. But in the second one it is in vain, because LCD technology doesn't give us the opportunity to consume lesser with black backgrounds. You can get more information at LaRepaweb.
