Setting the Video Display Type
The Video option lets you define the type of adapter you are
using for your primary display. If you connected your monitor
to the computer’s built-in VGA port, select EGA/VGA. If you
installed an optional video card, follow the guidelines in the
table below to select the correct adapter type.
