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.
