The DOS Screen Image on the LCD
If you use a DOS application that supports only VGA mode
(640x480 resolution) with your computer, the screen image might
appear smaller than the display size, as shown:
640 x 480
This is to maintain compatibility with DOS applications. To
expand the screen image to the same size as the actual screen,
you can use the

function. You can expand the
screen image by clicking on the LCD button ( ) in the
ThinkPad Configuration program or by entering the PS2 HVEXP ON
command. However, the image might look slightly distorted.
