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.
A high-resolution external monitor connected to the computer can display

up to 2048 horizontal and 1536 vertical pixels at up to 16M 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 SVGA and XGA 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, resolution, number of colors

and refresh rates.
