How to enhance HDR content on an SDR display ?

  • Hi,

    I have an SDR only display. A lot of my files are HDR files. Even if they play correctly, the colors are really washed out, which is to be expected. But I'm looking if there is a way to make them a bit better looking. I know Rpi4 doesn't support hardware tonemapping, like Hable tonemapping on PC. But maybe there is simpler way ? I think that it should be possible to get a better looking image just by tweaking normal image setting in Kodi like color and contrasts. But I would like those settings to apply only for HDR movies. I know a solution would be to get only SDR files, but that's not an option for me. Most of the time I don't have a choice between HDR or SDR.

    I have multiple questions :

    - Is there still no way to have full tonemapping (HDR2SDR) on an Rpi4 ?

    - Is there a way to achieve better looking HDR with normal settings ? Is there a way to get a profile that is applied only for HDR files ?

    - Is there other ways that could exist to get better HDR visuals on SDR displays ?

    Thanks in advance for any answer,

    Have a great day.
