program, and the necessary video drivers must be installed.
Before you change any of the default display settings, make a note of the default settings for future
reference.
NOTE:
Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-
installed operating system.
If you choose a resolution or color palette that is higher than the display supports, the settings adjust
automatically to the closest supported values.
