Netbooks screen aspect-ratio: suspect problem?

I'm trying to run a DOSbased app. which normally makes its own 'GUI';
on a Win7 based HP-Mini netbook. I start it from a *.bat.

And it shows error:
"C:\Windows\system32\cmd.exe
This system does not support full screen mode".

AFAICS it can only be set to 2 'resolutions' : 800 * 600
and some higher numbers.

I don't want to waste effort debugging it, if the problem
is the non-standard aspect-ratio [height to width ratio]
which this netbook has -- like many netbooks have.

What does "full screen mode" mean?

== TIA

This is DOS (cmd.exe) in regular windowed mode.

This is DOS (cmd.exe) in full screen mode. This takes up the entire screen.

The cmd.exe may be limited to 4:3 aspect ratios. That is about
all I can think of. The netbook screen should support things
like the basic VESA modes, which would help this situation.

If I use the moninfo program...

with my current monitor, under the real time entry it lists...

720 x 400p at 70Hz - IBM VGA

640 x 480p at 60Hz - IBM VGA
640 x 480p at 67Hz - Apple Mac II
640 x 480p at 72Hz - VESA
640 x 480p at 75Hz - VESA

800 x 600p at 56Hz - VESA
800 x 600p at 60Hz - VESA
800 x 600p at 72Hz - VESA
800 x 600p at 75Hz - VESA

832 x 624p at 75Hz - Apple Mac II

1024 x 768p at 60Hz - VESA
1024 x 768p at 70Hz - VESA
1024 x 768p at 75Hz - VESA

1280 x 1024p at 75Hz - VESA
1152 x 870p at 75Hz - Apple Mac II
1152 x 864p at 75Hz - VESA STD
1280 x 1024p at 60Hz - VESA STD

and if you use that program while in Windows, you may get
some idea what your computer supports in terms of resolution
settings.

When I run DOS in full screen mode, my desktop icons don't get messed
up, which suggests the resolution didn't change, and yet it would be
unlike a DOS display system to be flexible. The appearance of the
characters on the screen, looks like I might be running 1024x768 but
I can't be sure of that. I tried to find a command line resolution
check, but didn't succeed in locating one.
