If your Dell laptop screen appears too bright or dark, you should adjust the contrast. The contrast can be altered to best suit your needs. Dell laptops are simple to adjust the contrast. Unlike desktop monitors, laptop monitors don't have buttons or menus on the screen itself. However, buttons are available on the keyboard itself that allow you to change display settings. You can change many display settings through the display properties menu; however, contrast must be changed from the keyboard.
Start your Dell laptop. You must have the screen on in order to adjust the contrast. If you are using an external keyboard, you may need to disconnect it if the function keys are not available.
