Display Controller and Modes

Display controller

The display controller interprets software commands into hardware commands that turn particular picture elements (pels) on or off.

The controller is an advanced Video Graphics Array (VGA) that provides Graphics Array (XGA) support for the internal LCD and external monitors.

The following is available:

■13.3", 1280 horizontal × 800 vertical pixels

A high-resolution external monitor connected to the computer can display up to 2048 horizontal and 1536 vertical pixels at 16 million colors. (Depends on the model you purchased.)

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 modes, the most widely used industry standards.

This series are equipped with Mobile Intel® 965 Express display adaptors.

The video modes supported by the display chipset are shown in following tables.

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.

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.
