I generally agree.
However the tests performed eliminated UPS associated problems 
which could have been:
   1. defective UPS
   2. marginally overloaded UPS (I may be decades out of practice 
but ... ;]

Swapping physical location of monitors is a reasonable next step. 
I *doubt* that is problem. CAVEAT GOTCHA - there must be a test 
to distinguish between monitor locations and interface card or 
computer issues.

I confess.
I'm explicitly using this as a platform to promote good 
troubleshooting techniques ;/
