Satellite U200/PORTÉGÉ M500 Appendix B 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. As indicated below, there are two types of video modes. ■ Intel® 945GM model supports up to 2048 horizontal × 1536 vertical pixels. ■ Intel® 940GML model supports up to 1920 horizontal × 1440 vertical pixels. Refer to the table on the next page which describes in detail supported video modes. Because of the LCD's increased resolution, lines may appear broken in DOS mode. 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. 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 B-1
