Display Controller and Modes

Display controller

The display controller interprets software commands into hardware

commands that turn particular parts of the screen on or off.
The display controller supports VGA, SVGA and XGA modes on the

internal LCD display panel.
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.

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 colors 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.
