In the post-CRT computer monitor era, I'd argue that any screensaver is a total waste of energy and reduces the lifespan of the monitor. If it's not in use because the machine has sat idle for some time, I think you should just switch it off and forget about having a screensaver entirely. The sooner you turn off the back-light when the monitor is not being used, the better. LCD pixels kept in the same state on an LCD don't wear out and LCDs don't suffer screen-burn like CRTs used to, so the screen-saver is totally unnecessary for this. Also, when a blank-screen screensaver is activated, the back-light remains active unnecessarily using up some of its finite lifetime. Apart from for some marketing purpose if your monitor is facing your potential customers, can anyone give me a good reason for the continued existence of screen-savers since the screen-burn problem of CRTs is a thing of the past?
