OK. So today I received a "new" Kaby Lake i3-7100T test item, a HP Prodesk 400 G3 TFF (Tiny Form Factor). This product only has a DP1.2(++) as a graphical output, so a converter is needed to connect this to a HDMI port. I have 2 different versions of such a converter, one version = 100% an active one, the other one is doubtful if active, but some buyers say that they get 2160p@60Hz. I used the doubtful one for this.

So my test system beholds a 1080p passive 3D monitor with HDMI 1.4 ports, this one I always use for setting up and testing a system. When I want to use a system myself I move the item to my 4k 3D TV and completing the job there.

I installed Kodi MVC, the latest build, and set things up (connected to my 1080p 3D monitor). I took some 3D test files (from my NAS) and fired Kodi up.
I can select Hardware Based 3D within the settings, set this up as default, and when selecting my test-media, my monitor switches to 3D and a nice MVC 3D picture is putout on the screen.

In this setup it doesn't matter if the adapter = active or not, the output is max HDMI 1.4. 

Hah. Earlier today i ordered THIS PS176 chip based adapter (same chip as your first adapter) and THIS PS171 chip based adapter (same adapter as your second one). Should arrive saturday. Let's see.

According to THIS parade page, both PS176 and PS171 are active DP/HDMI converter, the PS171 maxes out at DP1.2/HDMI 1.4, the PS176 at DP1.4/HDMI 2.0. 

To be on the safe side, i also ordered THIS PS8121E chip adapter, which seems to be completely passive, but would require the DP1.2 port to actually be ++DP1.2, aka: able to output actual HDMI data stream, just at DP electrical level. 

Lets see if i will be as lucky as you are. Seemingly both PS171 and PS176 work for you.

Maybe try to get a PS178 based adapter then - that should also do HDR, althought it might require DP1.4a port.
