Appendix E

Display Controller and Modes

Display controller

The display controller interprets software commands into hardware
commands that turn particular pels on or off.

The controller is an advanced Video Graphics Array (VGA) that provides
Super VGA (SVGA) and Extended Graphics Array (XGA) support for the
internal LCD and external monitors.

Because of the LCD’s increased resolution, lines may appear broken in
DOS mode.

A high-resolution external monitor connected to the computer can display up
to 1280 horizontal and 1024 vertical pixels at up to 256 colours or 1024
horizontal and 768 vertical pixels at up to 16M colours.

The display controller also controls the video mode, which uses industry
standard rules to govern the screen resolution and the maximum number
of colours that can be displayed on screen.

Software written for a given video mode will run on any computer that
supports the mode.

The computer’s display controller supports all VGA and SVGA modes, the
most widely used industry standards.
