Dos 6.20 display issue

[Lucian Dragos]

Sorry but since there is no Dos forum I am posting this here..

I have a Compaq DESKPRO 2000 that's used for old games running MS-DOS 6.20/ Win 3.11 and a LCD screen with native 1024x768*60hz res. But I am having issues with the display. Dos seems to default to a odd 720x400*70Hz res but the display has some blurring and distortions at that which is annoying working in dos or editing text based files. But anything that runs in a normal 4:3 @60hz mode (I.E. 640x480,800x600 etc) such as most games or windows 3.11 displays fine..
I'm trying to remember if there was a command or program that forced Dos into a 4:3 mode since there is no display drivers to set..

you could do as they do here:

And use ansi.sys to force the text resolution

Edit: you would most likely want it to be 40x148 characters or 80x148 so.. values 1 or 3.
(as mentioned, ESC is to be replaced with altgr 27 character which current fonts don't quite handle)
If my google-fu works it should be something like this:

device=ansi.sys ESC[=1H

Edit2:This seemed too complicated and seemingly you should be able to do similar with prompt command. (&E is same as ESC in above) (actually, following link says that 18h is better sounding alternative)
prompt &E[=18h&p&g

That and better listing of possible options are here: http://www.robvanderwoude.com/ansi.php
