 Hi, the reason I am doing this as you know is there is a bug with RX cards where the wrong colour gamut is output when using 23p for SDR materiel. I cant use source resolution as this effects all resolutions so it would end up turning it off for 4k HDR stuff as well as SDR 4k stuff. I cant understand why it works fine with MPC-HC but not with KODI DS, its setup correctly obviously as it wouldn't work in MPC-HC.

It must be an issue with KODI DS, are we saying that KODI DS cant use MADVR profiles?, I dont think that can be the case, it could be however that it cant use profiles when there is already a separate switch for DIRECT3D11 built into KODI DS which there is, i've tried turning this on, off etc, no joy.

A few of us have expressed a preference to have all separate MADVR settings completely removed from DS for future releases and just have DS deal with the LIVE MADVR database, I think that would solve this but there are no future releases on the horizon so i'm having manually switch this on when I want to play HDR stuff or play that outside of KODI DS.   

 You have discovered the problem. It is the D3D11 switch in DSPlayer. madVR profiles work fine, otherwise.

I don't know what to recommend? You could set up an external player like MPC-HC for your SDR 4K files. It depends on how many of them there are and whether they are named appropriately.

I too would like to see madVR controls removed from DSPlayer, but this was aracnoz's design decision and he can't be reached. So... 

 i guess we just have to happy with what we have, I dont play HDR that often compared to other stuff so I might be be able to live with it playing externally. We'll just have to hope this gets fixed at some point but i'm not holding my breath. Its a real shame this player doesnt have a full time Dev anymore when its clearly the best one out there by a mile.
