Raspberry Pi 5: HDR not working

    popcornmix Is there anything I can help to get further into this issue or should I just live with that? I mean I can definitely live with it now that I know how to workaround it but I am willing to help and dive deeper into it if you want me to.

    It may help if you concisely explain what the current issue is (this thread has got quite long).

    My understanding is that on Pi5 in some circumstances when playing a HDR video, the display shows no signal.

    On a Pi4 with the same display and video, it plays correctly (with working hdr).

    Assuming that is the case, could you report the output of:

    kmsprint

    kmsprint -p

    for both the pi4 and pi5 when playing the video.
