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
Extended Graphics Array (XGA) and Super Extended Graphics Array Plus
(SXGA+) support for the internal LCD and external monitors.
Four models are available:
■ 15.0" XGA, 1024 horizontal × 768 vertical pixels
■ 15.0" SXGA+, 1400 horizontal × 1050 vertical pixels
A high-resolution external monitor connected to the computer can display
up to 1600 horizontal and 1200 vertical pixels at 16 M 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.
