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.

The display controller supports VGA, SVGA and XGA modes on the internal LCD display panel.

Two models are available:15.0" XGA, 1024 horizontal × 768 vertical pixels15.0" SXGA+, 1400 horizontal × 1050 vertical pixelsBecause 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 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 supports the mode.

The computer’s display controller supports all XGA and SXGA modes, the most widely used industry standards.

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.
