TECRA M2 Appendix C Display Controller and Modes 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), Super Extended Graphics Array (SXGA), Super Extended Graphics Array plus (SXGA+), support for the internal LCD and external monitors. Two models are available: ■ 14.1" XGA, 1024 horizontal × 768 vertical pixels ■ 14.1" SXGA+, 1400 horizontal × 1050 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 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 VGA and SVGA 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. User's Manual C-1
