This section deals with the hardware expansion capability of the video controller
chip in DOS applications.
Note
It is
not
necessary to read this section if you are a Windows® or OS/2 user and
do not plan to run DOS applications.
Unlike a CRT monitor, a flat panel display has a fixed horizontal and vertical
resolution. There are many DOS video modes whose resolution is less than that of
a flat panel display. In order to more efficiently make use of the flat panel
display’s active area, it is necessary to employ an expansion technique, which
stretches the lower resolution information to fill the higher resolution of the
display.
For example, DOS defaults to VGA video mode 3+. This is an 80 column, 25-row
text only screen whose effective resolution is 640 dots x 400 scan lines. Because
of this, the 800 x 600 display of the system will be partially filled by the 640 x 400
resolution of this particular mode. The expansion function uses lower resolutions
that will better utilize the display by stretching the information in an attempt to fill
the display.
Operating systems such as Microsoft Windows®
98 and Windows® NT use
display drivers to handle the different flat panel displays. Here, expansion is not
necessary since there is a specific driver for each resolution display.
Expansion does not add any resolution to the existing information; it simply
stretches the information to better fit the display. Text and graphic screens can
look somewhat grainy from the process of expansion.
