Kodi's settings "Adjust refresh rate" is setup with "On Start and Stop".
The video is still green.

Post the media info of the video file please.

Any ideas what the issue could be?
Thank you!

Can you post output of modetest when video is playing.

Browbeat · 2022-09-23, 00:01

Could you please let me know what modetest output is and how to get it as you expect?
Thank you!

You ssh in and run modetest.

Code:
modetest | pastebinit

will upload to a pastebin type site and report a short url you can post here.

Modetest ouput looks fine. HDR is enabled:

Code:
38 max bpc:

  flags: range values: 8 12

  value: 12

7 HDR_OUTPUT_METADATA:

  flags: blob

  blobs: value: 000000000200488a08393421aa9b9619 fc08133d4240e8033200e0031a010000

I note you are in 4096x2160@30 which seems surprising. Are you sure you have:
"Adjust refresh rate" is setup with "On Start and Stop".

Can you enable "hdmi_enable_4kp60=1" in config.txt (not essential for this file which is 23.976fps), but may be useful for other files.
Set up using recommended settings here.

It was initially like that but left to off after few tests.
I turned it back to start and stop. Didn't change anything.

I did it following this guide: https://wiki.libreelec.tv/configuration/config_txt
After a reboot, the HDR file plays correctly but:
- If I go back in the menu while playing it, the other movies pictures colors are not correct
- If I play a non HDR file, I totally lose picture on the TV

I have reverted it for now...
