If you find a picture on the Internet and want to use it as a wallpaper background, here s how to install it. Right click the image and the selections set as Wallpaper, or Save Picture as are available. I prefer to save the picture and then access the desktop properties, as explained above, to later try it. Scanned pictures can be used in the same way that Internet images are stored and used. The image on a monitor has the potential to burn itself into the inside surface if kept there for a long period of time.
Electrons exciting the phosphor on the inside of the display glass create the monitor image.
With this persistence being lower, the chance of the phosphor actually being burned is much less also. Screensavers today are more of a personal choice of what you want to see when you are not using the PC, but still want to keep the monitor turned on. They are used more for cosmetic, than for protection against burning the screen. There are many Freeware and Shareware screensavers available nowadays. SCR is a screensaver type file.
