Expanded Video Mode

When working in MS-DOSĀ® 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.
