Video Expansion

This section deals with the hardware expansion capability of the video controller
chip in DOS applications.
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. To more efficiently make use of the flat panel display's active
area, it is necessary to employ an expansion technique that 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. Therefore,
the 800 x 600 system display will be only 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. In those cases, expansion
is not necessary since there is a specific driver for each resolution display.
