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.
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 mode
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, and when the Display Properties
dialog appears, click on the Settings tab.
Because of the LCD’s increased resolution, lines may appear broken in
DOS mode.
