Is anyone experiencing that the nvidia drivers are being forced to update to 388.13. I had version 385.41 installed and experienced it automatically being updated without the software informing me three times tonight. each time it happened I was in the middle of a movie. I know 385.41 is the best driver to use for enabling and disabling HDR content and I want to stay on it. can anyone tell me what I need to do to prevent the drivers from updating besides disabling the auto download feature in Geforce Experience?

Thank you.
Back on 385.69 and switching from HDR to SDR and vice versa works perfectly.
 

Well, I had to manually install madvr in order to successfully play 4K HDR files with Kodi DSPlayer.
Only problem is that Windows doesn't turn HDR off when done with the HDR file. So I have to do it myself.
Win 10 (Fall update) with GTX 1080 GPU (latest drivers).

 i am trying to do this as well. but i can not for the life of me figure it out.. devices LG Oled 'B7, ONkyo 676, pc windows 10 with Radeon rx 550... 
i install kodi DSplayer 17.5 32bit. manually  install MadVR.. now this is where im lost. i dont know how to configure madvr or DSplayer to play my 4k remux with HDR..     

I didn't configure anything apart from enabling hardware decoding ("hardware decoder to use": DXVA2 copy-back, "device to use": automatic/GTX 1080) and choosing the correct "audio renderer" (Denon 4300) in the Kodi/Player/DSPlayer settings.
It was only the newer Nvida drivers messing it up by handing the HDR controls to Windows. Can't believe that MS still hasn't figured it out.
