Three Monitors DVI DVI Displayport-DVI Adapter

I have a Sapphire Dual-X R9 270X display adapter and Windows 10. I have two Dell U2412M monitors connected to the two DVI connectors on the display adapter as an extended display.

 

I want to connect a third DVI monitor so as to have three extended displays.

 

When I connect the third monitor using a passive display port to DVI adapter cable the monitor is detected by Windows but does not display.

 

But, I can get any two of the three monitors to work correctly using combinations of DVI and displayport (DVI DVI, DVI displayport), but never all three connected at once (only the monitors on the two DVI ports display when all three are connected, not the monitor on the displayport to DVI adapter cable).

 

What do I need to get the third monitor to work?
