computer or docking device. If your computer is connected to an external monitor and you try to change the brightness level, the Brightness Meter may
appear, but the brightness level on the external device does not change.
You can press the following keys to adjust display brightness:
Press <Fn> and the up-arrow key to increase brightness on the integrated display only (not on an external monitor).

Press <Fn> and the down-arrow key to decrease brightness on the integrated display only (not on an external monitor).

Switching the Video Image
When you start the computer with an external device (such as an external monitor or projector) attached and turned on, the image may appear on either the
computer display or the external device.
Press <Fn><F8> to switch the video image between the display only, the external device only, or the display and the external device simultaneously.
Setting Display Resolution and Refresh Rate
To display a program at a specific resolution, both the graphics card and the display must support the 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.
1. Click the Start button and click Control Panel.
2. Under Pick a category, click Appearance and Themes.
3. Under Pick a task..., click the area you want to change, or under or pick a Control Panel icon, click Display.

5. Try different settings for Color quality and Screen resolution.
NOTE:
As the resolution increases, icons and text appear smaller on the screen.
If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the entire screen cannot be
displayed at one time. For example, the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the rest of the screen,
use the touch pad or track stick to pan up, down, left, and right.
