Using the Display

Adjusting Brightness

When a Dell™ computer is running on battery power, you can conserve power by setting the display brightness to the lowest comfortable level.

• 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).

NOTE:

Brightness key combinations only affect the display on your portable computer, not monitors or projectors that you attach to your portable 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.

Switching the Video Image From Your Computer

Display To a Projector

When you start the computer with an external device attached (such as an external monitor or projector) 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

NOTE:

If you change the display resolution from the current settings, the image may appear blurry or text may be hard to read if you change the resolution to one not supported by your computer and display. Before you change any of the display settings, make a note of the current settings so you can change back to the previous settings if needed.

Using the Display

You can enhance the legibility of text and change the appearance of images on the screen by adjusting display resolution. As you increase resolution, items appear smaller on the screen. In contrast, lower resolution causes text and images to appear larger and can benefit people with vision impairments.

To display a program at a specific resolution, both the video card and the display must support the program, and the necessary video drivers must be installed.

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.

To set the display resolution and refresh rate for your display:

1 Click Start → Control Panel.

2 Under Appearance and Personalization, click Adjust screen resolution.

3 In the Display Settings window, under Resolution, move the slide bar to the left or right to decrease/increase the screen resolution.

NOTE:

For additional instructions, click How do I get the best display?
