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. The 15.0" TFT LCD panel displays up to
1024 horizontal and 768 vertical pixels and 1400 horizontal and 1050 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.
