640 x 480
If you use a DOS application that supports only 640 x 480 resolution (VGA
mode), the screen image might look slightly distorted or might 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 and click on LCD (
); then
select the Screen expansion function. (The image might still look slightly
distorted.)
Note: You can use the Fn + F8 keys to do the same thing if your computer
has screen expansion function.
