Resolved

I tried out the nightly (20260209-1a819bf) and it appears the issue is resolved. HDR is detected correctly. Logs below. Thanks for your help!

chewitt  popcornmix Thanks, I had a followup post, post#5 that you probably did not see yet that was still disabled (I guess because this is a new forum account) - It is above your comment. In that post I show logs of the RPI400 that does work. It shows the output of edid-decode as well on the 12.0.2 RPI400 that appears to work. Sorry my replies are slow, forum wants me to wait 2,400 seconds (40 min!) between replies.

This is the output of cat /sys/class/drm/card0-HDMI-A-1/edid | hexdump -v -e '/1 "%02x"' on the 12.0.2 PI (that works) [your command did not work]

This is the full log of the nonworking 12.2.1 pi with only one HDMI connected

This is the output of edid decode on nonworking 12.2.1

This is the output of the hexdump on nonworking 12.2.1

Ok so in an effort to be more helpful, here are the log files for the the RPI400 that is working

Looking at this in the area chewitt mentioned I see EDID information. This information is NOT for the TV it is connected to. I forgot that I did "hardcode" the EDIDs for where the PI normally is used and totally forgot when i moved it for troubleshooting purposes.

Ok so i am going to comment out that portion of cmdline.txt and try again.

it works still! here are the logs:

And i verified it was using the actual edid of the display. using:

edid-decode /sys/class/drm/card0-HDMI-A-1/edid

Output from above command:

So i think that would confirm its an issue with the newer version of LibreElec? Happy to give more info/data as needed.

Thanks so much for all the work you all have put into this. It really is great!

Thanks for your help. No I only have one display but two hdmi outputs. One is a Denon reciever (NO HDR), and one is a TCL TV with HDR. I use one output for sound and the other for video. I did try to just get HDR working by unplugging the AVR, with no change.

Good Morning,

I have been trying to get HDR to work with my RPI400 on the latest build (12.2.1) with no success. I have another RPI400 with an older build (12.0.2) and if i place it on this TV with these cables HDR works. However, this PI with the latest 12.2.1 LIBREELEC does not detect my display as HDR. Logs are uploaded at:

The RPI400 that does detect the display at HDR is running 12.0.2.

Thanks for any help or insight.
