To use graphic display drivers in 800 x 600 or 1024 x 768 resolutions, you must have a multifrequency monitor capable of displaying these resolutions. Standard VGA monitors cannot display them.
You can use the VGA utilities (also provided on the Utility diskettes) to take advantage of other special features of your VGA adapter. Even if you do not use any device drivers, you may want to install some of the VGA utilities. For complete instructions on installing and using the VGA device drivers and utilities, see the VGA Utilities Guide.
