Display controller
The display controller interprets software commands into hardware com-
mands that turn particular pixels 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 1600 horizontal and 1200 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 sup-
ports the mode.
The computer's display controller supports all SVGA and XGA modes, the
most widely used industry standards.
Some of display modes might not be supported depending on the external
monitor which you use.
If you are running some application (for example a 3D application or video
playback and so on), you may notice some disturbance, flickering or frame
dropping on your screen. If that occurs,adjust the resolution of display,
lowering it until the screen is displayed properly.
