I can't seem to get an HDR signal through my Onkyo TX rz3100 from my Sky Q box. Everything is fine if I connect it straight to the tv ( LG65E9 ) but no HDR if I run through the receiver. Ive set the Onkyo to deep colour on and the LG is set to hdmi ultra HD deep colour on. I have the Dolby Atmos set up so would rather run through the Onkyo if its possible. Anybody had this issue and resolved it?
