Have you tried a drive cycle to reset monitors? I don't like removing voltage or grounds trying to get a system to rerest? Sometimes it works and sometimes it causes problems. good luck. You can put your mouse arrow on text and click to enlarge. what monitors didn't run? Maybe there is an individual drive cycle for that monitor?
