Expanded Video Mode
When working in MS-DOS® text mode, you can select the font used to display text. Press
<Fn><F7> to toggle between regular video mode (serif font) and expanded video mode (a serif
font with extra leading). In expanded video mode, items in resolutions other than 800 x 600
expand to fill the screen, which is useful if you are working in 800 x 600 resolution on a
12.1-inch super video graphics array (SVGA) display.
NOTE: You may have difficulty using the display fonts feature with MS-DOS programs
that use downloaded fonts. For optimum video performance in these cases, do not use
expanded video mode.
Video Drivers and Video Resolution
The Dell-installed video drivers work with the operating system to let you customize the video
resolution, number of screen colors, and refresh rate of your display.
NOTE: The Dell-installed video drivers are designed to offer the best performance on
your computer. Dell recommends that you use only these drivers with your
factory-installed operating system.
