Should I use a screen saver under Windows 11, 10, ... etc.?
One often asks oneself whether a screen saver is good under Windows 11, 10, ... etc., but also under MAC-OS and Linux!
In the past, the screen saver had the purpose of protecting the CRT monitors from being burned in and from the resulting damage. The burn-in of pixels was prevented on the old screen. Today it is very different, tube monitors are no longer used. And the LED, LCD, TFT, IPS, etc. monitors cannot burn in ( only pixel errors occur ), regardless of the operating system or living room TV.
Screen savers are mainly used to personalize computers or to protect them with passwords after a certain period of idle time.
2.) Do screensavers save energy?
Screensavers do not save energy. In fact, many of today's sophisticated screen savers use more power than your computer would normally use. Even if a display goes blank (black), many screen savers continue to run and consume energy. Some screen savers will even prevent your PC from going to sleep, which is not a good thing.
3.) Increase energy efficiency on the computer!
To make your computer more energy efficient and have less impact on the environment, consider using display blanking instead of a screen saver. If you need the security that a password will be required to access your computer after the display disappears, configure your PC to use the blank screen saver and select the check box to display the login screen when you continue. The blank screen saver uses no more power than an empty computer and allows your PC to go into hibernation when the hibernation timeout is reached.
