There’s a myth that screen savers save energy – an obvious result of people attempting to understand what screen savers actually “save.” However, screen savers do not save energy – they use more energy to keep the display on and play the animation on the screen. Image Credit: Johannes Freund on Flickr Screen Savers vs. The fact that our monitors stay on and play animations when we’re away from them doesn’t really make sense anymore – it’s just something that many people have continued using out of habit. While many computers are still set to use an animated screensaver after the computer has been idle for a period of time, this isn’t really necessary. An LCD monitor will never burn in in the same way as a CRT monitor. LCD monitors work differently than CRTs – there are no phosphors to burn in. Modern computer monitors (and even televisions) aren’t CRTs – they’re LCDs. Screen savers display an animation that consistently changes, largely eliminating the problem of screen burn-in by ensuring that a single image isn’t on-screen all the time. Screen savers solved this problem by automatically activating when the computer wasn’t in-use.
