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 Ultra Extended Graphics Array (UXGA) support for the
internal LCD and external monitors. The 15.0" TFT LCD panel displays up to 1024
horizontal and 768 vertical pixels or 1600 horizontal and 1200 vertical pixels.
A high-resolution external monitor connected to the computer can display up to
2048 horizontal and 1536 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.
