How to set a screen saver on the computer?

Setting up a computer screen saver: Take the MAC system as an example. First, open the system preferences. Right-click the desktop and screen saver. Just choose your favorite screensaver.

The screen saver is a special program designed to protect the monitor. At that time, the original intention of the design was to prevent the computer from displaying the same picture for a long time because of unmanned operation, which led to the aging of the display and shortened its life.

In addition, although the screensaver is not specially designed for power saving, the screensaver program under Windows is generally dark, which greatly reduces the screen brightness and has a certain power saving effect. There are two kinds of monitors -CRT monitor and LCD monitor, and screen saver has different effects on them.
