Hello
I recently upgraded my home theater setup and ran into an issue with my AV receiver not passing through 4K HDR properly. My TV supports 4K HDR, my streaming device and gaming console are HDR-capable & the receiver is supposed to handle it—but for some reason, I either get no signal or it defaults to 1080p. Has anyone else faced this issue?
I’ve already tried swapping out HDMI cables with high-speed certified ones, ensuring HDMI-CEC is off, and checking the settings on both my receiver and TV. I also updated the firmware on all devices, but the problem persists .

I’m wondering if there’s a hidden setting I’m missing / if my AV receiver just isn’t handling HDR as advertised. Checked

Has anyone successfully resolved this type of issue? I’d appreciate any troubleshooting tips or workarounds.
Thank you !!
