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 and have not modified the de-
fault expansion mode in the BIOS setup,
Unlike a CRT, 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
3-18
