Many computer users have probably seen and even use a screen saver for their computer devices. This might come in an image, a text, a slideshow of chosen images, an animation or even a blank screen. For many, screen savers are just there to entertain whenever your computer had been idle for a certain amount of time. Many fail to recognize the other benefits of using a screen saver for their computer devices aside from entertainment purposes.


Did you know that screen savers were initially made in order to prevent computer monitors from experiencing phosphor burn-in? This is because computer monitors a few decades ago were made of cathode-ray tubes. But this kind of screens was prone to phosphor burn-in. This effect happens when the exposed areas of phosphor coating the inside of the screen changed permanently and a darkened shadow will materialize on these exposed areas because the same image had been displayed for a long period of time. In order to prevent this from happening, computer experts had developed screen savers that can change the image showing on the computer based on the preference of the user every now and then.

But now, technological advancements had paved the way for different methods that will make computer monitors not rely heavily on cathode ray tubes. In effect, screen savers have lost its main goal of preventing phosphor burn-in. But this does not mean that screen savers are useless today. In reality, screen savers have still different uses.


Advantages of using a Screen Saver

It cannot be denied that screen savers are mainly used for entertainment purposes. After all, they are fun to look at and some are even made in order to make a person relax and calm. There is no doubt that screen savers, especially those animated ones, are amusing to watch.


Another benefit of using a screen saver is that it can be used as a form of advertisement for businesses. Some companies use their logo as a computer’s screen saver in order to promote their business as well as their products. It is their way of informing people of the products and services that they offer and this method is actually effective.


Not many people know that screen savers can also be used in order to protect your computer and all of the files stored in it when you have to leave it for some time.  Some screen savers offer a password protection feature that is beneficial for those who have sensitive information in their computer devices.

Thus, no one can access your computer unless they have your password.
