Do you remember screen savers? Chances are, you haven’t used one since the early 2000s. However, they still exist on your computer if you dig into the settings.
Apple has introduced new screensavers in recent updates, featuring stunning 4K videos of cityscapes and nature. On the other hand, Microsoft hasn’t focused much on new screensavers, with the ones in Windows 11 dating back to Windows Vista from 2007. Despite the changes over the years, screensavers remain a feature in major operating systems like Linux distributions.
It’s interesting to note that screensavers, a feature that hasn’t been widely used for decades, are still present on our computers. Unlike floppy drives or PS/2 ports, screensavers have endured. So, why do screensavers still exist, and what was their original purpose?
Screensavers used to solve a specific problem
Screen savers were developed due to the now-obsolete cathode ray tube (CRT) displays. In the 1990s, CRT monitors required extra space behind the screen because of their technology, which could cause “burn-in” if a static image was displayed for too long.
CRT displays suffered from permanent burn-in issues, where pixels could get stuck if the same image was displayed for an extended period. This led to the development of screensavers, which prevented burn-in by displaying dynamic content when the computer was idle.
Screensavers like 3D pipes, toasters, and abstract patterns were designed to constantly change the display, ensuring no part of the screen remained static for too long.
These days they’re mostly just for fun
Modern LCD monitors don’t face the same burn-in issues as CRT displays. Additionally, computers can now put the display to sleep after a period of inactivity, conserving energy. Despite these advancements, screensavers are still included in operating systems like Microsoft and Apple’s for entertainment purposes.
While screensavers may not serve their original function, they offer a fun way to personalize your computer. From nature footage to interactive designs, screensavers can still bring joy to users. Some screensavers even have practical uses, such as displaying a clock or contributing to scientific research through projects like Folding at Home.
Even though screensavers may not be as essential as they once were, they continue to be a nostalgic and enjoyable feature on our computers.
