So i think i am a gluton for pain and went back in to see what i could learn. I managed to get the hub working with a single monitor. My old syncmaster 226cw. But only part way. The system (both windows display settings ans catalyst cc) says the resolution is 1680×1050 but there is a black bar on the right side of the display of unused pixels and when i use the menu on the actual monitor it says the resolution it is receiving from the computer is 1809×1053 60hz. So the black bar is the extra 130ish pixels width the monitor is being told by something to display, but the windows/ccc are only using the now squished 1680. The native resolution is 1680×1050.
I have tried changing resolutions. These will change without removing the black bar (and the output from the computer detected by the monitor firmware still says 1809×1053. I have tried reinstalling drivers, power cycling, detecting monitors, hitting the scan button on the hub.
When i plug the monitor directly into the computer dp using the mini dp to dp adapter from the hub and the same dp to dvi adapter i was using to the monitor, it is recognized fine with the correct resolutions and refresh in both windows and the monitor firmware menu.
I think this may be why the acer monitors are saying no signal. If they are being sent an incompatible resolution they may not be taking the signal at all.
