Points to Consider When Using the DOS Screen on the LCD
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.
This is to maintain compatibility with DOS applications.

When installing an operating system,
you must install the display driver
before you can use an external
monitor.

an attached monitor:
