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), Extended Graphics Array (XGA), Super Extended Graphics Array
(SXGA), Super Extended Graphics Array Plus (SXGA+) and Ultra Extended
Graphics Array (UXGA) support for the internal LCD and external monitors.
Four models are available:
◆ 14.1" XGA, 1024 horizontal x 768 vertical pixels
◆ 15.0" XGA, 1024 horizontal x 768 vertical pixels
◆ 15.0" SXGA+, 1400 horizontal x 1050 vertical pixels
◆ 15.0" UXGA, 1600 horizontal x 1200 vertical pixels
A high-resolution external monitor connected to the computer can display up to
2048 horizontal and 1536 vertical pixels at up to 64k colors or 1920 horizontal and
1440 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.
