I am running MS Windows 3.1 in 1024x768 w/ 256 colors mode.  However, my 
screen has an annoying flicker that I can't seem to get rid of.  I have
a Diamond SpeedSTAR SuperVGA graphics card w/ 1 meg ram  and am using an 
Optiquest 1000 monitor.  According to the docs the monitor can support 
any vertical frequency from 47-90 Hz (either interlaced or non-int.) and
the card can support both 60 & 70 Hz in non-interlaced 1024x768 Mode.
But, when I try these settings on the card, the monitor becomes fuzzy and
blurry.  In order to use 1024x768 mode, I am running at 44 Hz (interlaced).

Does anyone use Win 3.1 with a similar setup ?  Can you e-mail me how you 
have your sys configured.

Does anyone know the sync polarities for the Optiquest 1000 or what monitors
it emulates ?

E-mail me if you have any suggestions or questions.   THANKS !!!
