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.

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.
