2015 MacBook Pro 13", U3415W, U2715H, Mirror not extended?

Hi,

I got the 2015 MacBook Pro 13" with Intel Iris Graphics 6100 GPU

It is connected via DP to a U3415W which is connected to U2715H via DP

I turned DP 1.2 on on the 34" and made sure it's off on the 27"

Both the displays work but the picture on the 27" is a mirror of the 34" and under arrangement in mac os menu I can only see the 34" screen.

1. Is this setup supported for multi monitors?

2. What should I do to make it work?

MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.6)

I'm not entirely sure what Apple claims but according to Intel the 6100 is not listed as a GPU that can display on three monitors simultaneously, nor is OS X set up for this feature on models that will support it.
