Are Screensavers Still Relevant? When to Use Them (And When Not To)
Remember the old days when you spent hours hunting for the coolest screensavers? You probably haven't done that for some time, and you aren't really missing out on anything if you haven't.
In fact, in the world of modern screens, screensavers are wholly unnecessary. Screensavers once served an important purpose, but they're now obsolete. Feel free to never use a screensaver ever again—but that being said, there are a few reasons why you might want to.
The original purpose of a screensaver was simple: to save your screen.
But this was back when computer monitors primarily consisted of cathode ray tubes (CRT). CRT monitors create images by emitting red, green, and blue lights at various intensities to display different colors.
When a CRT monitor shows the same image for too long, however, the color permanently settles on the screen, causing what is known as screen burn-in or image burn.
So, for example, a static element on the screen—like the Windows taskbar or the Mac Menu bar—would, over time, get burned into the screen. Even when you switched the screen off, you could see an outline of the taskbar's ghost.
When Screensavers No Longer Matter
While the logic of screensavers is solid, it's only relevant today if you still use CRT monitors or plasma screens. LCD and LED monitors don't have image burn problems as they do, and since laptops and monitors are now primarily LCD or LED, the purpose of the screensaver is moot.
But if like seeing moving pictures when not using your computer, by all means, use one, just a matter of choice really!
