So why do we use screensavers? They were originally created to protect computer monitors from phosphor burn-in. In earlier CRT monitors, images that were displayed for long periods of times would become burnt into the glass surface and would leave a ghosting effect on the screen. Lucky today, modern monitors don't suffer from this same problem; however, we continue to use screensavers for a few simple reasons:
Entertainment - Screensavers are fun. With such a giant selection of free screensavers, it's still fun to have them.
General Look - People don't want a boring screen, they want something that stands out and a screensaver can do that for you.
Security - You can set your computer to lock requiring a password to get back in if your screensaver has turned on.
If that isn't enough of a reason for you try our screensavers, the last reason is that they are free! There isn't much that you can get for free today; however, you'll get thousands of free screensavers still today from ScreenSaverCastle.com
