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.
A high-resolution external monitor connected to the computer can display up to
2048 horizontal and 1536 vertical pixels at up to 16M colors.
The display controller also controls the video mode, which uses industry stan-
dard 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 SVGA and XGA modes, the most
widely used industry standards.
