Setting Up a Screen Saver

If you walk away from your computer and leave the monitor on, the same image might be on your screen for hours at a time. Years ago, this would tend to "burn in" the image permanently on the screen. To prevent such screen damage, developers created screen savers, which are programs that kick in when the display hasn't changed in a while. A good screen saver contains some kind of moving image, so no section of the screen is consistently bright or dark.

Monitor technology eventually improved to the point that burn-in is not a serious concern. In addition, many monitors now have an energy-saving feature that allows a monitor to turn off automatically if its display hasn't changed for some period of time.

But even though screen savers are no longer needed for their original purpose, many people continue to use them because they are pleasant to look at. They also discourage random passers-by from reading the document you're working on when you step out for coffee. If your computer is set up with user accounts, the screen saver can require you to log back in when you return, so others can't use your computer (without your password). Screen savers like Mystify Your Mind or Curves and Colors make attractive geometric patterns that can be soothing to watch; others like 3D Maze create a more active mood.

In offices with multiple networked computers, the screen saver can display the computer's name, suitably colorized and animated. You can also download screen savers from the Internet, enabling you to display the latest Harry Potter images when you're not working. Or you can use the My Pictures Slideshow screen saver to cycle through pictures of your grandchildren or your vacation in Bali.

Selecting a Screen Saver

To select and activate a screen saver, follow these steps:

  1. Open the Display Properties dialog box by right-clicking any empty spot on the desktop and selecting Properties from the shortcut menu.
  2. Click the Screen Saver tab of the Display Properties dialog box, shown in Figure 11-5.

tip Windows comes with a choice of several screen savers, but that's just the beginning. Additional screen savers are available over the Internet, and most of them are free. You can begin your search at C|NET's Web site at http://www.download.com, which lists screen savers in the "utilities" department. You can also try looking on the Web site of your favorite book, TV show, or movie to see whether there is a promotional screen saver.

Configuring Your Screen Saver

While you have the Screen Saver tab selected, you can make a number of choices about how your screen saver functions:
