Changing Screen Resolution on Windows Vista

Screen resolution is a setting to determine how much information can be displayed on the computer screen. It is measured horizontally and vertically using pixel unit. At low resolution like 640 x 480, fewer items fit on the screen, but they are larger and easier to see. On the other hand, at high resolution like 1600 x 1200, more items fit on the screen and they appear sharper but smaller.

1. Right-click on empty area on desktop background, then click Personalize.

2. On Personalization window, click Display Settings text.
