Jellyfin 4K Videos Look Dull, Faded, or Desaturated? Heres Why
#!/The problem
> The colors appear dull because the video is in HDR10 format with a wide color gamut (bt2020) and brightness range, which requires HDR-capable hardware and software to display correctly. Without proper HDR support, the colors and brightness are misinterpreted, leading to desaturation. Enabling tone mapping fixes this by converting the HDR signal to fit your displays SDR capabilities, restoring vibrant and accurate colors.
#!/The solution
> You need to enable tone mapping. To do this (as of Jellyfin web client version 10.10.3), login to jellyfin web app as an admin, open the hamburger menu on the top-left side, click Dashboard, then expand Playback and select Transcoding. Scroll down to the section Enable Tone Mapping, check the box, and save your settings. Now start a new playback, and you will see proper colors.
