Ok, so 3 work, but 4 do not. Thats becasue the ati radeon pci i have doesnt support dual monitors. The 7000 being delivered this week does though. I will post back with my answer.
By the way, as you know I have a broken ankle still, I just crawled down a flight of stairs with an old Apple monitor in lap to test this out. Now thas a mad modder!
