Screen resolution and color depth are (Kids web site) the only
Screen resolution and color depth are the only settings in this chapter thatapply to alluser accounts. That s because those options affect the videohardware directly, and hardware is oblivious to user accounts. All usershave access to exactly the same hardware and hardware settings. Using the bit number as an exponent of 2 tells you the number of different colorsthe screen can display. For example, 32 bits of color (232) gives you 4,294,967,296different colors, ideal for viewing photographs and video. A lower resolutionsuch as 224(16,777,216 colors) 216(65,536 colors) can make photos look blotchy. Saving Display Properties SettingsIf you make any changes to the settings in any of Display Properties tabs, remem- ber that you can save those settings under any name of your choosing. Just clickthe Appearance tab in Display Properties; then click the Save As button. You canaccept the default file name, My Favorite Theme, or enter a new name. Onceyou ve saved a theme, its name will be visible in the Theme drop-down list on theThemes tab, so you can easily apply the entire theme just by selecting its name. When you ve finished changing settings, click the OK button in the DisplayProperties dialog box. All your settings will be applied, and the dialog box willclose. If you want to make further changes, just reopen the Display Propertiesdialog box again by right-clicking the desktop and choosing Properties or byopening the Display icon in Control Panel. Is My Screen All Whacky? The first time you switch from one screen resolution to another, the image onyour monitor might be off center, as in the example at left below. Or the imagemight be too tall, too wide, too short, or too narrow, like in the center example. To fix that, you need to adjust the Width, Height, Horizontal Center, and VerticalCenter adjustments on your monitor. You can t adjust the previously mentioned monitor settings using either mouseor keyboard. You must use the controls that are right on the monitor itself or onyour notebook computer. The only place to get information on using those con- trols is in the manual that same with your monitor or computer. Once you findthe right controls, you should have no problem sizing the desktop so that it fills the screen as in the example above on the right.
