Display Controller and Modes
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) support for the internal LCD and external
monitors.
The 15.0" TFT LCD panel displays up to 1024 horizontal and 768 vertical
pixels.
A highresolution external monitor connected to the computer can display
up to 2048 horizontal and 1536 vertical pixels at 16M colours
The display controller also controls the video mode, which uses industry
standard rules to govern the screen resolution and the maximum number
of colours 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.
Video modes
The computer supports video modes defined in the tables below. If your
application offers a selection of mode numbers that do not match the
numbers on the table, select a mode based on mode type, resolution,
character matrix, number of colours and refresh rates. Also, if your
software supports both graphics and text modes, the screen display may
appear to operate faster using a text mode.
