PEOPLE are freaking out over the real reason screensavers exist and it has sent the internet into meltdown.
It turns out they have a far more serious screen-saving role than computer users previously thought.
Screensavers have covered idle computer screens for decades and the most well-known have become etched in the minds of millions.
The famed DVD logo that bounces across the screen and gets closer to hitting the corner each time was so mesmerising that people would often sit and stare at it.
It was even turned into a much-used meme.
And yet, the true reason they exist is no laughing matter.

The original function of a screensaver was to protect a monitor from damage that could occur when a single picture was left on for an extended time.
It keeps moving so that it doesn't stay too long and scar the screen with a visual pattern due to "phosphor exhaustion".
Over time, this can lead to discolouration or blemishes on the screen.

Meanwhile, the long-running claim that screensavers make devices slower has been debunked by tech whizzes.
According to the experts behind Lenovo, the reality is actually the opposite.
"If your computer is running slowly then having an active screen saver could help improve performance by reducing power usage for certain parts such as video cards or CPUs.
"This means they don't have to work as hard trying to keep everything running at full speed when nothing needs doing.
"Ultimately, they don't directly increase speeds, but they certainly won't slow them down either so it's worth looking into setting one up if yours hasn't already got one installed."

This means the data being shared can't be intercepted by a third party, the Mail reported.
