Display Controller and Modes
Display controller
The display controller interprets software commands into hardware
commands that turn particular parts on the screen on or off.
As indicated below, there are two types of video modes.
■ Intel
®
945GM model supports up to 2048 horizontal × 1536 vertical
pixels.
■ Intel
®
940GML model supports up to 1920 horizontal × 1440 vertical
pixels.
Refer to the table on the next page which describes in detail supported
video modes.
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.
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.
Because of the LCD’s increased resolution, lines may appear broken in
DOS mode.
