Adjusting the Resolution of Your Display The display resolution defines the clarity of images on your display. As you increase the resolution, items appear smaller on the screen. As you decrease resolution, text and images appear larger. Before you change any of the display settings, make a note of the current settings so you can change back to them if needed. NOTE: Use only the Dell recommended video drivers, which are designed to offer the best performance with your Dell-installed operating system. FOR MORE INFORMATION: To learn more about display resolution, see "Adjusting Display Settings With the Vendor Video Card Control Panel" on page 246. Also, see Windows Help and Support: click Start or → Help and Support. 48 Monitors and Displays
