Using the Display
Using a DOS Application with Your Computer
When you use a DOS application that supports only VGA mode
(640-by-480 resolution) with your computer, the screen image might
look slightly distorted or might appear smaller than the display size,
as shown in the following table. This is to maintain compatibility with
DOS applications.
PS2 command for screen expansion:
Page 277.
The screen expansion function in the ThinkPad Features program
lets you set the screen image to the same size as the actual screen
size, but it may look slightly distorted, except when display mode is
set to “CRT only”.
Note:
When display mode is set to
640-by-480 resolution and 65 536
colors, screen expansion is not
available.
Warning:
* When you select Both, do not
attach an external display that
supports only VGA mode
(640-by-480 resolution).
Otherwise, the external display
screen will be scrambled and the
output will not be displayed, or the
screen might be damaged.
If screen expansion is set to off, the screen image appears as
follows:
