"No Video Modes Available" Error

Hello,
 
I installed and setup AdvancedMame for DOS.  I ran the "Advcfg" utility to
setup the monitor configuration.  When I try and run a game I get the
following error:
 
"No Video Modes Available"
"Unable to start video Emulation"
 
Does this mean that I cannot play this particular game under AdvandedMame?
If so, is it because my Monitor is the limiting factor, or my Video card?
The video card that I am using is supported under the DOS AdvancedMame
release (ie: it's on the list).
 
Thanks,
 
Hugh
