I have read an article before that when the ordinary CRT monitors leave temporarily, it is best to enable screen saver, which is good for display. But recently I heard that this method is not applicable to LCD. Is that reasonable?

This is because when CRT monitors are used, they shine through the electrons bombarded with phosphors. If the phosphors are in a high working state for a long time, they will naturally affect their service life. Therefore, it is better to use screen saver from this perspective.

But the principle of liquid crystal display has changed. It mainly relies on backlight to irradiate liquid crystal molecules. The life of the screen depends on the backlight, rather than the liquid crystal molecules. Therefore, it can enter the control panel, open the "power option", and set the "shutdown monitor" to "10 minutes later" to play a protective role.
