Q: MacPro black screen on startup

I Have a 2009 MacPro tower. Worked fine two weeks ago when I shut it down, now when I turn it on all I get is a black screen.

 

I hear the boot up chime, I can tell by listening to the HD that OS X loads and gets to the login prompt.  I've reset pram, held down shift on boot up, reseated the video card. The monitor acts like it's not getting a signal. Tried hooking it up to a tv, same result.

 

Any ideas?

Mac Pro, OS X El Capitan (10.11.6)
