garbled text in dos graphics screen!

Hello,

I'm really hoping this is an old problem that I just haven't been able to
find an answer to. I am using a simulations package that runs in a DOS
screen (full-screen mode) and ultimately plots results in a graphics screen
that (I assume?) is in vga mode. The problem is that the text on these
screens (for menu options, axis labels, etc.) is completely garbled and
"smeared" so that it is unreadable.

It may be related that during setup of NT, the text on my screen is nearly
unreadable, and completely so after moving my mouse over the text. A strange
"smearing" takes place in a region around the mouse. Has anyone else seen
this? What is the cause of this strange problem?

Hardware details:
PPro200 on Natoma board
Number Nine 771 or Matrox Millenium II video card (both give same result)
Nokia Multigraph 447X monitor

Running: NT4 WS + SP3

Hi ehymel,

I am afraid that your graphics-cards are not fully compatible
to the vga-mode your programm uses. The smearing of the mouse
suggest that, though this could also be a mouse-driver problem
(most likely a problem with the graphics-card though).

Have you tried to run the program in dos-window-mode (not full
screen). Does this smearing appear there too?

If not, then your card is not 100% vga compatible (if that is the
mode your program uses), which is odd, put in times where you
have your drivers to take care of how to access your graphics
card, not impossible.

Greetings,

Thanks for the information, os. I have tried running in a window, but the result is a locked program. The conclusion must be that whatever video mode this program is using will not work on my workstation. Too bad...
