You can manually select a preset mode or you can select Auto Mode that applies a

Brightness and Contrast can also be directly adjusted from the Basic tab.
NOTE: When multiple Dell monitors are connected, select “Enable
display matrix control” to apply brightness, contrast and color presets
controls to all monitors.
