I will check which hardware decoding I'm using. Which one is recommended?

Can anyone tell me what's going here? This happens when I try to play 4K mkv via Mpc-HC or Kodi. As soon as playback stops, everything is back to normal. 1080p files play without any issue.

I'm using Nvidia 1050 card with latest drivers. Output is going to JVC projector. Projector automatically goes to HDR mode so I'm guessing it has to something MadVr settings?

 You didn't know that all HDR video looks like that?

If you are using D3D11 Native hardware decoding, try DXVA2 (copy-back) instead. I can't remember if this fixed it, but I have seen the pink wave before. It looks like bad video decoding, to me.

 Any update on the pink screen? No need to give up if the first attempt didn't fix it.
