Text Modes | Graphics Modes

The built-in VGA subsystem can display both text modes and graphics modes. Text modes use only text characters, although many of the characters are suitable for creating simple line drawings. Graphics modes are used for complex drawings and graphical user interfaces, but these modes also allow text characters to be created in a variety of shapes and sizes.

Extended-video modes provide resolutions beyond those contained in the original VGA standard. Some application programs require video drivers to take advantage of the extended-video text and/or graphics modes. Load each driver before using it for its corresponding application program. The application program may also need to be configured to use the new driver. Consult the application program's documentation to find out how to configure the program and where to place the driver on the hard-disk drive.

NOTE: If a VGA expansion card is installed in the computer, reset the jumper labeled "EVGA" to disable the built-in VGA subsystem.

For multifrequency monitors running the Monitor Select utility (monitor.exe), the flicker that occurs when an application program uses high-resolution video modes can also be significantly reduced.
