Display controller
The display controller interprets software commands into hardware
commands that turn particular picture elements (pels) on or off.
The controller is an advanced Video Graphics Array (VGA) that provides
Extended Graphics Array (XGA) support for the internal LCD and external
monitors.
The following is available:
■ 15.0", 1024 horizontal × 768 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 modes, the most widely
used industry standards.
Some models in this series are equipped with a Mobile Intel
®
945GM
Express Chipset, and some models are equipped with an ATI Radeon
®
Xpress 200M Chipset.
The video modes that are supported by each chipset are shown in the
