It is actually a USB 3.0 port, so the power is higher. And I do see the thunderbolt icon at the power up, but it does not seem to be present after that.
Anyhow, since the problem with HDR is now solved (and was not definitely related to the supply) I think we can close the discussion.
Thanks again to everybody for the support!
Hi Hias,
Yes, I am actually powering it from the USB of my TV, and I have configured it in such a way that when it detects the HDMI off signal from the TV it shuts down (I've verified that the power stays on for enough time after the TV shuts down so that Libreelec can shutdown cleanly).
Will try going the downclock route and see if it is enough, otherwise I will use an external supply.
BTW, Yesterday I've tried the procedure you've suggested for creating the custom EDID using AW EDID Editor, and it works flawlessly! Now I have HDR10 working again through my old (but not osolete 
) AVR (at least up to 23.976 framerate)!
Thanks Hias for your incredible patience and support!

Hi Hias,
Thanks for your reply. I am 99% sure that the AVR is the culprit here.
Do you think it would be possible to force a custom EDID to try to force HDR?
Thanks.
Here you go:
Libreelec 11.0.6 (HDR working):
https://paste.libreelec.tv/included-quagga.log
Libreelec 11.95.2 (HDR not working):

The second one was generated straight after updating and playing the same exact files.
Let me know if further details are needed. Thanks!
Hi all,
I am currently using Libreelec 11.0.6 on a Raspberry Pi 4 with a Yamaha RX-V477 receiver and a LG G3 55 TV.
This receiver came originally with HDMI 1.4 support but was later updated to 2.0 (I assume HDMI 2.0 draft).
Libreelec 11.0.6. is showing HDR support, and playing some files with HDR10 content and 23.976 framerate works (LG TV correctly detects HDR content and I can see that it is working).
However, LibreELEC 12 Beta2 does not show any HDR support.
Any ideas/suggestions?
