Motherboard Asrock J4205-ITX ---- Denon AVR X6200W ---- Sony KD-65XF9005 HDR work fine.
Alright, thanks! Both boards have an HDMI 2.0 port, so that shouldn't be the issue. The 4205 has more USB ports and a Pentium J4205, but actually has an HD505, whereas mine has a 600, so actually a newer generation etc, so this shouldnt be the issue.
Theelichtje I don't know if this is applicable to your Onkyo model... hdmi_4k_onk.pdf
Thanks for this! Although it's already set to enhanced unfortunately.
I'll connect the PC directly to the TV tomorrow, and see if the TV picks the HDR signal up then.
