The DOS full-screen looks
smaller.
If you use a DOS application that supports only 640×480 resolution (VGA
mode), the screen image may look slightly distorted or may appear
smaller than the display size. This is to maintain compatibility with other
DOS applications. To expand the screen image to the same size as the
actual screen, start the ThinkPad Configuration Program (refer to the
online user's guide) and click LCD; then select the Screen expansion
function. (The image may still look slightly distorted.)
Note: If your computer has screen expansion function, you can use the
Fn+F8 keys to expand the screen image.
