*nix noob here. I moved a Plex server from Windows and everything is working flawlessly except HDR. The client side should be good (NVIDIA Shield and LG OLED TV that both rendered HDR fine under Windows) and I know my server hardware (10th gen i7 NUC) is capable so I’m assuming I’m just missing some packages and/or config. This is a fully-updated EndeavourOS installation but I think I remember having the same issue under raw Arch.
I don’t, that was a mistake. Just HDR to HDR.
I’m still confused. All the HDR processing should be done on the client side if it is an HDR capable display playing a compatible format. The Shield can play most formats so that shouldn’t be the issue. How do you know HDR isn’t displaying properly?
