The brightness on your Dell laptop or desktop monitor can negatively affect your viewing experience when the screen is too dim. Dell laptops include automatic battery-conservation settings that dim the screen when the laptop runs on battery power alone. Using a keyboard shortcut will override the automatic settings and can be done any time. The Dell desktop LCD monitor provides function keys on the front panel for brightness and contrast adjustment. Use these keys to adjust the monitor to your specific viewing needs.
