This machine has two video cards, the first supports two monitors, the second card has one monitor.
Ran Xorg -configure which generated xorg.conf.new & a log file Xorg.0.log.1
This process discovered both cards but only two of the three monitors.
Ran X -config /root/xorg.conf.new which generated Xorg.0.log.2 where all three monitors can be seen.
