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 Super VGA (SVGA) and Extended Graphics Array (XGA) support for the internal LCD and external monitors. The displays up to 1400 × 1050 (SXGA+). The controller also supports simultaneous display on the internal LCD and on an external monitor.
A highresolution external monitor connected to the computer can display up to 1600 horizontal and 1536 vertical pixels and up to 64K 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 table 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, consider the following points:
■If your software supports both graphics and text modes, the screen display may appear to operate faster using a text mode.
■The LCD’s highest graphics resolution is 1400 horizontal × 1050 vertical lines.
