>Check the specs on your HDMI converter and make sure it supports that version of DP++ and see what kind of quirks it could have with plugging it straight to HDMI
I checked all that.
The adapter work fine since it's a passive adapter.
If the source supports dual-mode DisplayPort (also known as DP++ which is what I have), then all you need is a passive adapter because the source can perform the conversion from DP to HDMI.
Which is what I see on both devices, the TV see HDMI being bulged in, and the mini PC see HDMI sink.
