This time HDR started up, for a moment, after a few seconds the monitor showed no signal.

The cable is original, purchased from an official dealer.

Nightly build : kernel panic on first boot. When I find the time I will try other versions later.

LibreElec in the PC version plays 4K movies with HDR on this monitor without any problem. Unfortunately only from a flash drive, because bad shim signature after installation, and I don't want to disable secure boot. And Linux doesn't support HDR yet, supposedly next month.

The Raspberry Pi 4 plays videos in 4K but without HDR.

On the default settings, the monitor indicates "no signal" in 4K resolution, only using dtoverlay=vc4-kms-v3d,cma-512 works.

I bought this Raspberry Pi in January 2020 and so far it doesn't work what was in the specification. Is there any chance it will ever work?
