42 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, perform the steps in the following section

that corresponds to the operating system your computer is using.

If the video resolution setting is higher than that supported by the display, the computer enters pan

mode. In pan mode, the entire video image cannot be displayed at one time, and the taskbar that usually

appears at the bottom of the desktop may no longer be visible. To view the parts of the video image that

are not visible, you can use the touch pad or track stick to "pan" (or move) the image up, down, left, and

right.

NOTICE: You can damage an external monitor by using an unsupported refresh rate. Before adjusting the refresh

rate on an external monitor, see the user’s guide for the monitor.
