The workaround has held up for 5 days.  I use xscreensaver options "Only One 
Screen Saver", "SlideScreen", Blank after 10 minutes, No lock screen, No Display 
Power Management.  This keeps the monitors busy.

I tried turning on Display Power Management and ended up with frozen 
monitors.

It looks as if the nvidia driver 460.91 (and other versions) breaks when 
attempting to save energy with iiyama 2783QSU monitors.
