Display Controller and Modes

Display controller

The display controller interprets software commands into hardware
commands that turn particular parts on the screen on or off.
Because of the LCD's increased resolution, lines may appear broken in
DOS mode.
The display controller also controls the video mode, which uses industry
standard rules to govern the screen resolution and the maximum number of
colors that can be displayed on screen.
Software written for a given video mode will run on any computer that
supports the mode.

Video modes

Video mode settings are configured via the Display Properties dialog. To
open the Display Properties dialog, click on the Start button, select Control
Panel, and from the Control Panel click on Appearance and Themes and
then click on Display. When the Display Properties dialog appears, click on
the Settings tab.
