Texas Instruments TravelMate 2000 - Manual (Page 70)

Setting Up the LCD
Text Mode
In text mode, text is displayed on a 25-line screen in either 40 or 80 columns in CGA, EGA and VGA modes.
Graphics Mode
The TravelMate 2000 LCD screen can display high-quality graphic images. The VGA mode gives the best
results, since it has the highest screen resolution. If your application does not support VGA, then EGA is an
alternate high-resolution display mode. CGA is available for applications that do not support the higher
resolution modes.
LCD Modes
The TravelMate 2000 has two LCD modes-standard and expanded-which are selected by accessing the Set
Up screen, as described earlier in this chapter. In standard mode, the display area for CGA, MDA and EGA
does not fill the LCD screen, so there are borders at the top and bottom of the screen. In expanded mode, the
displays are expanded vertically-by duplicating a line every few lines-to use as much of the 640 by 480
screen as possible.
Setting the Display Mode
The MS-DOS MODE command allows you to specify the text display mode on the TravelMate 2000 LCD or
on an external monitor. For the LCD type the command:
MODE 40 - for 40 chars/line or
MODE 80 - for 80 chars/line.
Refer to the MODE command in your MS-DOS manual for a detailed description.
Note: The 40-column text display is not supported in the MDA and HGC modes.
