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.

Two models are available:

❑13.3" XGA, 1024 horizontal x 768 vertical pixels

❑14.1" XGA, 1024 horizontal x 768 vertical pixels

A high-resolution external monitor connected to the computer can display up to 1600 horizontal and 1200 vertical pixels at up to 64k colors or 1024 horizontal and 768 vertical pixels at up to 16M colors.

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.

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