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 LCD Internal Panels. Various
video modes can be displayed on each LCD Internal panel. Refer to the
table on the next page which describes in detail supported video modes.
■
17" WXGA+, 1440 horizontal × 900 vertical pixels
■
17" WUXGA, 1920 horizontal × 1200 vertical pixels
Because of the LCD's increased resolution, lines may appear broken in
DOS mode.
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.
