What is a Screensaver?
First of all, a screensaver is a software program to prevent “Phosphor Burning” on a CRT and plasma computer monitors by blanking the screen or filling it with moving images or patterns when the computer was not in use.
Good screensaver programs should have the following features:
-
A dark background or scene: This is to save power consumed by the display.
Moving objects or scene: This is to avoid pixel burn-in. Fixed objects must be dark.
Slow motion: The scene must be appeasing.
Silent running: If you add sounds, use low-level ones and/or music.
Sensitive: It must stop on any user action (mouse move, clicking, keyboard typing,…).
Modern CRTs are much less susceptible to burn-in than older models due to improvements in phosphor coatings, and because modern computer images are generally lower contrast than the stark green- or white-on-black text and graphics of earlier machines. LCD computer monitors, including the display panels used in laptop computers, are not susceptible to burn-in because the image is not directly produced by phosphors (although they can suffer from a less extreme and usually non-permanent form of image persistence).
They can be usually set up to launch automatically, waiting a specified amount of time after the last action made by a user. Then the screensaver switches the image to black, or produces some animation effects, slideshows, music,…
How to install/ uninstall screensavers?
Most downloadable screensavers are delivered as a .exe file, only click on the file and it automatically installed on your PC, for uninstall, look an uninstall or remove option in the program or by clicking the start menu, then all programs (or program files).
