The MSKB doesn't have much on "Full Screen DOS"...
Cannot Switch Away from Full-Screen MS-DOS-Based Program
ALT+ENTER Does Not Always Switch MS-DOS Prompt from Full Screen to a Window
It could be a Video Adapter driver problem...

Maybe un/re-install your monitor & Video Adapter...
For the Monitor...
(1) Boot to Safe Mode
(Hold F5 as you boot or CTRL for the Startup Menu)
(2) "START, Settings, Control Panel, System, Device Manager tab"
(3) Open the Monitors branch, & Remove all entries.
Perhaps, FIRST, even in Normal Mode, note what is installed
similar to below for the Adapter. That is...
(a) D-Clk the monitor there for Properties, Driver tab.
(b) Click the Update Driver button, then "Next".
(c) Bolt "Display a list...", & click "Next".
(d) Bolt "Show all hardware".
Examine the two panes to see what is currently installed.
That is likely what you wish to end up with, after step (4).
(4) Boot to Normal Mode.
Hopefully, it will be rediscovered & installed. Then, if still
necessary, here is the rigmarole of the Display Adapter...
The first thing to do is to remove the video adapter you have
installed. Right-click on the desktop; choose "Properties" from the
drop-down menu; select "Settings;" click on the "Advanced" button; and
click on "Adapter". An adapter is a program that tells Windows how to
deal with a specific video card. Make note of the adapter that is
currently installed. Then, change the adapter to "Standard Display
Adapter (VGA)" and restart the system.
[That is: Click "Change, Next, bolt 'Display a List...', Next, bolt
'Show all hardware', scroll left pane to top, select '(Standard display
types)', select 'Standard Display Adapter (VGA)' in right pane, click
This will remove the current adapter and replace it with a generic VGA
adapter that works with all video cards. You will not like VGA because
it supports only 16 colors, but the purpose of installing it is to get
rid of whatever was there before.
Next, return to the adapter screen and install an adapter that matches
your video card. This may or may not be the adapter that you are
using now. Examine the materials you received with your computer to
see if they include a CD-ROM or floppy disk that contains the correct
video adapter. Or go to the Gateway website and see if they have an
adapter for you to download. Or check the website of the company that
made your video card.

Thanks or Good Luck,
There may be humor in this post, and,
Naturally, you will not sue,
