any way to make VGA monitor's high-freq whine go away?

[metaHipster]

I've got my first vertical cabinet, Metacab Jr. up & running but notice that in some games e.g. Ms. PacMan, etc I hear a very piercing high-frequency whine.  What little I know of monitors tells me there's some refresh rates piped by mame32 in those games which is making the monitor cry. 

Since the whine doesn't occur in mamewah/windows (at 1024x768, 75hz), is there any way to hack the mame32.ini to keep those refresh settings?  it's not all games so maybe the 31000 doesn't have issues vs 15000 that does?

dunno but am willing to give things a shot if anyone has suggestions.  I really don't want to have to go *gasp* buy a part (e.g. LCD Monitor) for the cab, so am hoping there's a software fix.

Thanks!

In standard mame there is a "-noswitchres" option. Should be a checkbox somewhere in the mame32 settings.
