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 colours 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.
■ Some of display modes might not be supported depending on the
external monitor which you use.
■ If you are running some applications (for example a 3D application or
video playback and so on), you may see 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. You could
also disable Windows Aero™ to help correct this situation.
