3 days agobest way to play back HDR movies, especially Dolby vision, is to dual boot LibreElec, specifically THIS build that is getting DV+FEL to work on intel, amd and nvidia graphics.
within a standard Linux operating system these days you can get easily basic HDR working in MPV or kodi etc, but more advanced formats are poorly supported. that said, a decent modern TV can usually run jellyfin, plex, emby, kodi etc. and play the files directly off your computer via SMB/NFS or a usb disk with reasonable format support. getting full lossless atmos audio and the best HDR support requires specific dedicated players, or the libreelec option above if you are OK dual booting.
there are easy gui based boot usb creators for linux if you arent comfortable with dd for some reason.
