theme is a background, plus colors, screensavers, icons, fonts, set of sounds and mouse pointers. Changing the theme allows you to personalize the appearance of your desktop. The desktop’s appearance is governed by a Control Panel called Display that contains the Display Properties Window. (Sounds and Mouse Pointers are contained in separate Control Panels.)

To open the Display Properties window:

      The sample window will allow you to preview the theme you have just selected.

4.   Click OK

      The monitor graphic displayed in the Desktop window will allow you to preview   the theme you have just selected.

Note: You can select your own graphic to be the desktop background by choosing the browse button. Browse to picture you have stored on your computer.

·         A shortcut for making any picture your desktop background is to right-click on the picture file, and then select Set as Desktop Background.

      The monitor graphic displayed in the Desktop window will allow you to preview   the screen saver you have just selected.

Note: To change the way a screen saver runs, click Settings. Each screen saver has its own relevant settings.

Note: As you make selections, they will be displayed in the graphic located at the top of the appearance screen.

A screen’s resolution is measured in pixels, with a pixel representing a single dot. Switching to a higher resolution allows you to see more items on the screen at one time, but it makes it item appear smaller. When there are more pixels on the screen, the refresh rate (number of times the display is updated) is slower, and flickering may be more noticeable.

To change the screen resolution:

1.      Open the Display Properties window by right-clicking on an empty space on          the desktop and clicking on properties.

2.      Click the Settings Tab.

3.      Drag the slider to select the resolution you want to use.

4.      Click OK.

Color Quality enables you to change the number of potential colors displayed on your monitor and available to applications. The more colors, the crisper and truer the images, especially with photographs and movies.

To change the color setting:

2.      Click the Settings Tab.

3.      Click the dropdown arrow under Color Quality to display the available choices. Click the color setting you want to use.

4.      Click OK.

Note: Changes you make to the color settings will affect all the users set up on your computer.

Note: If you have games or other programs that need to display 256 colors, you can select it temporarily. Right-click the program’s icon on the desktop, or on the Start menu, then click Properties – Compatibility tab. Select the Run in 256 colors check box. Whenever you close the program, your screen reverts to its original color quality.
