Screensavers: To Use or Not to Use? Exploring the Reasons

During computer inactivity, screensavers, software that blanks or displays moving graphics, safeguard your screen from damage or prying eyes. They were originally designed to avoid burn-in on older computer displays, hence the name “screen saver.” Modern displays lack burn-in issues. Yet, screensavers persist for aesthetics and concealing sensitive data left on screens.

Why screensavers were invented

Burn-in was an issue with older Cathode-Ray Tube (CRT) monitors. Any image that was shown on the screen for an extended period of time was “burnt into” the screen. You would still see a ghost image even if you totally switched off the monitor.

With static pictures, like interface components, this is especially problematic. For instance, the Windows taskbar may etch into the screen because it is usually static at the bottom of the screen. An old television with a news channel and a ticker at the bottom may have the ticker permanently burned into the screen. A burn-in may develop on an ATM that mostly shows a single image.

In essence, the phosphors inside the CRT that generate light have been unevenly worn down, making certain portions of the screen darker. Screen savers fixed this issue by turning on automatically while the machine was idle. By preventing a single picture from being displayed continuously on the screen, screensavers significantly reduce the risk of screen burn-in.

Are screensavers harmful to LCD screens?

The output of your LCD screen can change over time if you use a screen saver. Most LCD panels lose brightness over time, even with typical use, and leaving the display on with a screen saver only hastens this process. A vital part of an LCD monitor’s construction is typically the fluorescent backlight. If a display becomes too weak, it is usually best to replace it entirely. To be clear, if you frequently leave your LCD monitor on at night, you might need to buy a new one sooner. As a result, it is advised to use screensavers primarily for entertainment. With our current technology, the use of screensavers does not save anything. It is more effective to have an LCD display preset to shut down by itself after an extended period of inactivity.

What impact do screen savers have on system power saving?

Screen savers do not conserve energy, they require more energy to keep the display on and play the animation on the screen. A graphics-intensive 3D screen saver that leverages your graphics hardware to produce intricate 3D scenery would take even more energy, putting your computer into game mode and burning electricity when you’re not even at your computer.

Modern computers have power-saving features. Instead of configuring your computer to display a screen saver while you’re not using it, you may set the computer to automatically turn off its display when it’s not being utilized. This will reduce the use of electricity as well as laptop battery life. 

To change when your computer automatically turns off its display, follow these steps:

  • Press the Windows key to open the Start menu, type “Edit Power Plan“, and press Enter.

Anyone who uses an LCD monitor may increase their return on investment by having it powered off when not in use. Therefore, it is best to avoid using screensavers if you have an LCD monitor. Although they were first used for both fun and functional reasons, they should only be used for amusement now.


The option to utilize screensavers is yours, but you should be aware that doing so waste electricity. Alternatively, you may make a concession and briefly utilize a screen saver before shutting off your display. For instance, you could program a screen saver to start after five minutes and have the display turn off on its own after ten minutes.
