Thanks, Tom!  I will try these tomorrow.  They do look eerily similar to 
what I have already tried myself, but I'll let you know.

One frustration I have discovered is that changes made in a Windows 
session (not Chimera session) do not seem to retain their effects.   I 
was successful over the weekend trying to get Chimera to see the card, 
but the stereo frame rate was screwed up--I'd guess going at 15 instead 
of 60 Hz despite it recognizing the 120 Hz monitor. The image wobbled 
back and forth.

As I continued to play with settings, it lost it, so I reset everything 
and went straight to what worked.  This failed.  So something in the 
sequence I went through initially did something to the card which was 
not reproduced later.

All experimenting was tested by restarting Chimera.

Will keep in touch as I drop back down the rabbit hole...
