I don't know about that, the hot cathode fluorescent tube driver board from an old 486 laptop I dismantled had a nice variable brightness PWM inverter in it.Nigel Goodwin said:an LCD takes full power all the time

Clearly the best thing as far as the environment is concerned is to only replace your CRT monitor with a new TFT monitor when it wares out or gets broken.
Nigel Goodwin said:The power consumption of an LCD and CRT are pretty much the same, bearing in mind that an LCD takes full power all the time, and a CRT depends on beam current (brightness). The 1/10th power consumption is a complete work of fiction - it's nothing like that, and may even actually be higher!.
