Q: 2009 Mac Pro w/HD 5770 to Dell U2414H Monitor via Mini Display Port not working

2009 Mac Pro w/HD 5770 to Dell U2414H Monitor not working with mini Display Port cable to Display Port cable.

 

I'm using Mini Display Port to Display Port and its not working.  I want to Daisy Chain two monitors and use the second Display Port outlet from the HD 5770 to connect a third monitor via HDMI.

 

DVI to HDMI works fine

MDP adapter to HDMI works fine

Using a MacBook to connect with a Mini Display Port to Display Port works fine

Mac Pro, OS X Yosemite (10.10.5)
