Video Modes
This appendix lists the video modes supported by the display adapter, and identifies the characteristics of each mode.
The tables have these columns:
Mode is the mode number in hexadecimal; it is generally used by programmers to specify video modes in programs.
Type identifies the display adapter that first supported the mode, and specifies whether the mode is text or graphics.
Resolution is the measure of the screen's dimensions in terms of horizontal and vertical pixels (in graphics modes), or rows and columns of characters (in text modes).
Grid is the default number of pels per character.
LCD Colors is the maximum number of simultaneous colors, or shades of gray, that the mode can display on the built-in screen.
CRT Colors is the maximum number of simultaneous colors, or shades of gray, that the mode can display on an external monitor.
Scan Freq hor/vert is the horizontal and vertical scanning frequency in Hertz. This is for external monitors only.
This table lists the video modes for the Tecra 780CDM/DVD computer:
