If You Have Display Problems
If the computer is receiving power, but nothing appears on your display (such as light, text, or graphics) or the display image does not appear as you would expect, try the
following measures to resolve the problem:
NOTE: When you run the computer on battery power, set the computer's brightness control to the lowest setting that affords comfortable viewing. You
can conserve up to 5 percent of battery power by using the minimum brightness setting.
NOTE: The video drivers that Dell installed for you are designed to offer the best performance on the computer. Dell recommends that you use only
these drivers with your Dell-installed operating system.
NOTE: If you are using an external monitor, see the documentation that came with the monitor to determine the correct refresh rate.
NOTE: You may need to adjust the vertical and horizontal size and position controls on your external multifrequency monitor to properly display
extended-video modes.
